im trying to create a xml file using php.everytime i run the code the page displayes the code from a certain point as text on the screen.the code i hav is as follows:
<?php
if(!$dbconnet = mysql_connect('I took out the details')){
echo "connection failed to the host.";
exit;
}
if (!mysql_select_db('siamsati_db')){
echo "Cannot connect to the database.";
exit;
}
$table_id = 'events';
$query = "SELECT * FROM $table_id";
$dbresult = mysql_query($query, $dbconnect);
$doc = new DomDocument('1.0');
$root = $doc->createElement('root');
$root = $doc->appendChild($root);
while($row = mysql_fetch_assoc($dbresult)){
$ooc = $doc->createElement($table_id);
$occ = $root->appendChild($occ);
foreach ( $row as $fieldname => $fieldvalue){
$child = $doc->createElement($fieldname);
$child = $occ->appendchild($child);
$value = $doc->createTextNode($fieldvalue);
$value = $child->appendChild($value);
}
}
$xml_string = $doc->saveXML();
echo $xml_string;
?>
and the page when displayed shows:
createElement('root'); $root =
$doc->appendChild($root); while($row =
mysql_fetch_assoc($dbresult)){ $ooc =
$doc->createElement($table_id); $occ =
$root->appendChild($occ); foreach (
$row as $fieldname => $fieldvalue){
$child =
$doc->createElement($fieldname);
$child = $occ->appendchild($child);
$value =
$doc->createTextNode($fieldvalue);
$value = $child->appendChild($value);
} } $xml_string = $doc->saveXML();
echo $xml_string; ?>
is there something ive missed.ive checked all the quotes thinking it was that at first but they all seem to be right.any suggestions on what im doing wrong are much appreciated?
Set the content type to be XML, so that the browser will recognise it as XML.
header( "content-type: application/xml; charset=ISO-8859-15" );
In your code Change it to:
// Set the content type to be XML, so that the browser will recognise it as XML.
header( "content-type: application/xml; charset=ISO-8859-15" );
// "Create" the document.
$doc = new DOMDocument( "1.0", "ISO-8859-15" );
+++I think you can do something like this
<root>
<?
foreach ( $row as $fieldname => $fieldvalue){
?>
<events>
<fieldname><?=fieldname; ?></fieldname>
<fieldvalue><?=$fieldvalue; ?></fieldvalue>
</events>
}
?>
</root>
In the code you've posted here the initial <?php tag is missing...

Below code is for export data from mysql table as xml file. I have tried several code but not getting the result. Please check and help me.
Currently getting result is

When we are dealing with XML and HTML, the best way to act is ever through a parser.
In this particular situation, operating with a parser guarantees a valid XML and a clean, short code.
After defining mySQL query, we init a new DOMDocument with version and encoding, then we set his ->formatOutput to True to print out XML in indented format:
$query = "SELECT AB.id, AB.name, AB.firstname, AB.street, AB.zipcode, AB.city_id, CI.city FROM address_book AS AB INNER JOIN city AS CI ON AB.city_id = CI.id";
$dom = new DOMDocument( '1.0', 'utf-8' );
$dom ->formatOutput = True;
Then, we create the root node and we append it to DOMDocument:
$root = $dom->createElement( 'addressbook' );
$dom ->appendChild( $root );
At this point, after executing mySQL query, we perform a while loop through each resulting row; for each row, we create an empty node <address>, then we perform a foreach loop through each row's field. For each field, we create an empty childnode with tag as field key, then we append to childnode the field value as CDATA and the same childnode to <address> node; at the end of each while loop, each <address> node is appended to root node:
$result = $mysqli->query( $query );
while( $row = $result->fetch_assoc() )
{
$node = $dom->createElement( 'address' );
foreach( $row as $key => $val )
{
$child = $dom->createElement( $key );
$child ->appendChild( $dom->createCDATASection( $val) );
$node ->appendChild( $child );
}
$root->appendChild( $node );
}
Now, your XML is ready.
If you want save it to a file, you can do it by:
$dom->save( '/Your/File/Path.xml' );
Otherwise, if you prefer send it as XML you have to use this code:
header( 'Content-type: text/xml' );
echo $dom->saveXML();
exit;
If you want instead output it in HTML page, you can write this code:
echo '<pre>';
echo htmlentities( $dom->saveXML() );
echo '</pre>';
See more about DOMDocument
Go to your phpmyadmin database export and select xml in file format.
Replace
$xml .= "<![CDATA[$value]]>";
with
$xml .= $value;
IF you want to have it format it "nicely" in the browser add an:
echo "<pre>";
before the:
echo $xml;
Please note this WILL BREAK the XML file, but it will look good in the browser.... if that is what you are after...
I would suggest to use libraries like SimpleXMLElement etc. to create XML documents.
$xml = new SimpleXMLElement("<?xml version=\"1.0\" encoding=\"UTF-8\" ?><{$root_element}></{$root_element}>");
while($result_array = $result->fetch_assoc()){
foreach($result_array as $key => $value)
{
$address = $xml->addChild("address");
//embed the SQL data in a CDATA element to avoid XML entity issues
$addressFields = $address->addChild('"' . $key . '"', "<![CDATA[$value]]>");
//No need to close the element
}
}
Header('Content-type: text/xml');
print($xml->asXML());
I'm trying to pull all the data from my users table and display it in XML format. The connection works fine and everything as I have a login and registration set up fine, but I can't seem to get this to display anything other than a white screen.
I've found lots of different tutorials on how to do it with mysql but not mysqli. what am i missing?
generatexml.php
<?php
include 'connection.php';
$xml = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
$root_element = $config['users'];
$xml .= "<$root_element>";
if ($result = $mysqli->query("SELECT * FROM users", MYSQLI_USE_RESULT)) {
while($row = $result->fetch_assoc())
{
$xml .= "<".$config['users'].">";
//loop through each key,value pair in row
foreach($result_array as $key => $value)
{
//$key holds the table column name
$xml .= "<$key>";
//embed the SQL data in a CDATA element to avoid XML entity issues
$xml .= "<![CDATA[$value]]>";
//and close the element
$xml .= "</$key>";
}
$xml.="</".$config['users'].">";
echo $xml;
}
}
?>
I struggle a lot to find out this solution in mysqli format but nowhere i found the solution. Below is the solution i figured. Run this demo and map it your requirement, surely it will help.
<?php
//Create file name to save
$filename = "export_xml_".date("Y-m-d_H-i",time()).".xml";
$mysql = new Mysqli('server', 'user', 'pass', 'database');
if ($mysql->connect_errno) {
throw new Exception(sprintf("Mysqli: (%d): %s", $mysql->connect_errno, $mysql->connect_error));
}
//Extract data to export to XML
$sqlQuery = 'SELECT * FROM t1';
if (!$result = $mysql->query($sqlQuery)) {
throw new Exception(sprintf('Mysqli: (%d): %s', $mysql->errno, $mysql->error));
}
//Create new document
$dom = new DOMDocument;
$dom->preserveWhiteSpace = FALSE;
//add table in document
$table = $dom->appendChild($dom->createElement('table'));
//add row in document
foreach($result as $row) {
$data = $dom->createElement('row');
$table->appendChild($data);
//add column in document
foreach($row as $name => $value) {
$col = $dom->createElement('column', $value);
$data->appendChild($col);
$colattribute = $dom->createAttribute('name');
// Value for the created attribute
$colattribute->value = $name;
$col->appendChild($colattribute);
}
}
/*
** insert more nodes
*/
$dom->formatOutput = true; // set the formatOutput attribute of domDocument to true
// save XML as string or file
$test1 = $dom->saveXML(); // put string in test1
$dom->save($filename); // save as file
$dom->save('xml/'.$filename);
?>
If you have access to the mysql CLI, here's my quick hack for achieving this:
$sql = "SELECT * FROM dockcomm WHERE listname = 'roortoor'
and status IN ('P','E') and comm_type IN ('W','O')
and comm_period NOT IN ('1','2','3','4') order by comment_num";
$cmd = "/usr/bin/mysql -u<person> -h<host> -p<password> <database> --xml -e \"$sql\";";
$res = system($cmd ,$resval);
echo $res;
Here is a solution using php only. You where close to getting it right. This was the key part of the code that I changed "$row as $key => $data" used $row instead of $result_array, ie. iterate through row not the result_array (this contains the entire dataset). Hope this helps someone.
if ($result->num_rows > 0) {
// output data of each row
while($row = $result->fetch_assoc()) {
$value .="<record>\r\n";
//loop through each key,value pair in row
foreach($row as $key => $data)
{
//$key holds the table column name
$vals = "\t" . "<". $key . ">" . "<![CDATA[" . $data . "]]>" . "</" . $key . ">" . "\r\n";
$value = $value . $vals;
//echo $value;
}
$value .="</record>\r\n";
$count++;
}
} else {
// echo "0 results";
}
$conn->close();
One possible issue could be this line:
if ($result = $mysqli->query("SELECT * FROM users", MYSQLI_USE_RESULT)) {
Try the procedural approach instead of the object oriented approach. I do not know if $mysqli is defined in connection.php, but it is possible that you mixed it up.
if ($result = mysqli_query('SELECT * FROM users', MYSQLI_USE_RESULT)) {
This could resolve the white screen error.
I noticed two other things:
(1) One tiny effectiveness issue:
$xml = '<?xml version="1.0" encoding="UTF-8"?>';
So you do not need to escape every single quotation mark.
(2) One serious XML issue: The root element needs to be closed before you echo your $xml.
$xml .= "</$root_element>";
echo $xml;
Generally, for your purpose, it would be safer to use PHP's XMLWriter extension, as already proposed.
This is my code which I expected to generate normal RSS. However, after each <item> there's a </channel></rss><?xml version="1.0"?><rss version="2.0">. What do I need to change so that this is only declared at the end of the script as it should be?
Do let me know if I've missed out any important information.
function jobscrape($title, $link, $root, $description, $job_location) {
header("Content-Type: application/rss+xml; charset=UTF-8");
$xml = new SimpleXMLElement('<rss/>');
$xml->addAttribute("version", "2.0");
$channel = $xml->addChild("channel");
$channel->addChild("title", $title);
$channel->addChild("link", $link);
$channel->addChild("description", "This is a description");
$channel->addChild("language", "en-us");
$html = file_get_contents($link);
$doc = new DOMDocument();
libxml_use_internal_errors(TRUE);
if(!empty($html)) {
$doc->loadHTML($html);
libxml_clear_errors(); // remove errors for yucky html
$xpath = new DOMXPath($doc);
$row = $xpath->query($job_location);
if ($row->length > 0) {
foreach ($row as $job) {
$jobs = array();
$entries = array();
$jobs['title'] = $job->nodeValue;
$jobs['description'] = "This is a description";
$jobs['link'] = $job->getAttribute('href');
array_push($entries,$jobs);
foreach ($entries as $entry) {
$item = $channel->addChild("item");
$item->addChild("title", $entry['title']);
$item->addChild("link", $entry['link']);
$item->addChild("description", $entry['description']);
}
echo $xml->asXML();
}
}
else { echo "row is less than 0";}
}
else {
echo "this is empty";
}
}
Create one XML document, add all your items to that document, and call ->asXML(); on the complete document at the end (instead of on each fragment every time you go around the loop).
Looked at a few other SO posts on this but no joy.
I've got this code:
$url = "http://itunes.apple.com/us/rss/toppaidapplications/limit=10/genre=6014/xml";
$string = file_get_contents($url);
$string = preg_replace("/(<\/?)(\w+):([^>]*>)/", "$1$2$3", $string);
$xml = simplexml_load_string($string);
foreach ($xml->entry as $val) {
echo "RESULTS: " . $val->attributes() . "\n";
but I can't get any results.
I'm specifically interested in getting the ID value which would be 549592189 in this fragment:
<id im:id="549592189" im:bundleId="com.activision.wipeout">http://itunes.apple.com/us/app/wipeout/id549592189?mt=8&uo=2</id>
Any suggestions?
SimpleXML gives you can easy way to drill down in the XML structure and get the element(s) you want. No need for the regex, whatever it does.
<?php
// Load XML
$url = "http://itunes.apple.com/us/rss/toppaidapplications/limit=10/genre=6014/xml";
$string = file_get_contents($url);
$xml = new SimpleXMLElement($string);
// Get the entries
$entries = $xml->entry;
foreach($entries as $e){
// Get each entriy's id
$id = $e->id;
// Get the attributes
// ID is in the "im" namespace
$attr = $id->attributes('im', TRUE);
// echo id
echo $attr['id'].'<br/>';
}
DEMO: http://codepad.viper-7.com/qNo7gs
Try with xpath:
$doc = new DOMDocument;
#$doc->loadHTML($string);
$xpath = new DOMXpath($doc);
$r = $xpath->query("//id/#im:id");
$id = $r->item(0)->value;
Try:
$sxml = new SimpleXMLElement($url);
for($i = 0;$i <=10;$i++){
$appid= $sxml->entry[$i]->id->attributes("im",TRUE);
echo $appid;
}
I have a question.
I have the xml
http://maps.googleapis.com/maps/api/geocode/xml?address=new+york&sensor=true
I want to read from example
GeocodeResponse/result/geometry/location/lat
and
GeocodeResponse/result/geometry/location/lng
maybe using XPATH and this is what i have so far ...
<?php
$Address = "new+york";
$Query = "http://maps.googleapis.com/maps/api/geocode/xml?address=".$Address."&sensor=true";
$XmlResponse = file_get_contents($Query);
$doc = new DOMDocument();
$doc->loadXML($XmlResponse);
$root = $doc->getElementsByTagName( "GeocodeResponse" );
foreach( $root as $val )
{
$hrefs = $val->getElementsByTagName( "status" );
$status = $hrefs->item(0)->nodeValue;
foreach( $hrefs as $val2 )
{
$hrefs2 = $val2->getElementsByTagName( "type" );
$type = $hrefs2->item(0)->nodeValue;
echo "Type is: $type <br>";
}
echo "Status is: $status <br>";
}
?>
Can i have some advices?
maybe i can use
$xpath = new DOMXPath($xml);
$hrefs = $xpath->evaluate("/page");
UPDATE!!
I have managed to get the result by this ...
$xpath = new DOMXPath($doc);
$res = $xpath->evaluate('//GeocodeResponse/result/geometry');
$root = $doc->getElementsByTagName( "location" );
foreach( $root as $val )
{
$hrefs = $val->getElementsByTagName( "lat" );
$status = $hrefs->item(0)->nodeValue;
echo "Status is: $status <br>";
}
but i want something without foreach like
$xpath = new DOMXPath($doc);
$res = $xpath->evaluate('//GeocodeResponse/result/geometry');
$hrefs = $val->getElementsByTagName( "lat" );
$status = $hrefs->item(0)->nodeValue;
echo "Status is: $status <br>";
Is this possible?
You may want to switch to JSON that is much easier to parse:
http://maps.googleapis.com/maps/api/geocode/json?address=new+york&sensor=true
$json = file_get_contents('http://maps.googleapis.com/maps/api/geocode/json?address=new+york&sensor=true');
$geocodeResponse = json_decode($json, true);
foreach($geocodeResponse['results'] as $result){
echo $result['geometry']['location']['lat'].', '.$result['geometry']['location']['lng'] .'<br>';
}
