I am creating an address book xml feed from a MySQL database, everything is working fine, but I have a section tag which gets the first letter of the surname and pops it in that tag. I only want this to display if it has changed, but for some reason my brain isn't working this morning!
Current code:
<?php
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
echo "<data>";
do {
$char = $row_fetch["surname_add"];
$section = $char[0];
//if(changed???){
echo "<section><character>".$section."</character>";
//}
echo "<person>";
echo "<name>".$row_fetch["firstname_add"]." ".$row_fetch["surname_add"]."</name>";
echo "<title>".$row_fetch["title_add"]."</title>";
echo "</person>";
//if(){
echo "</section>";
//}
} while ($row_fetch = mysql_fetch_assoc($fetch));
echo "</data>";
?>
Any help on this welcome, don't know why I can't think of it!
And if you still want to generate XML manually, I suppose, something like this will work:
$section = "NoSectionStartedYet";
while ($row_fetch = mysql_fetch_assoc($fetch)) {
$char = $row_fetch["surname_add"];
if ($char[0] != $section)
{
if ($section != "NoSectionStartedYet")
{
echo "</section>";
}
$section = $char[0];
echo "<section><character>".$section."</character>";
}
echo "<person>";
echo "<name>".$row_fetch["firstname_add"]." ".$row_fetch["surname_add"]."</name>";
echo "<title>".$row_fetch["title_add"]."</title>";
echo "</person>";
}
echo "</section>";
To be sure that your XML is valid it is better to build a DOM tree, here is an example from the PHP manual:
<?php
$doc = new DOMDocument;
$node = $doc->createElement("para");
$newnode = $doc->appendChild($node);
echo $doc->saveXML();
?>

The following is my code:
<?php
include('simple_html_dom.php');
$rowdate;
$html = new simple_html_dom();
$html->load_file('http://www.forexfactory.com/calendar.php');
foreach($html->find('.calendar_row') as $e)
{
$date=$e->find('span.date');
if ($date[0] != "")
{
$rowdate=$date[0];
}
$time=$e->find('.time');
$currency=$e->find('.currency');
$impact=$e->find('.impact');
$event=$e->find('.event');
echo $rowdate;echo ",";
echo $time[0];echo ",";
echo $currency[0];echo ",";
echo $impact[0];echo ",";
echo $event[0];
echo "<br>";
}
The above code works fine however $impact is not displayed at all while if you open the url in your browser directly and see the source code , we can see that the impact class is present within each calendar_row
Can anyone please guide me as to what I am doing wrong ?
Instead of:
$impact = $e->find('.impact');
echo $impact[0];
You want:
$impact = $e->find('.impact', 0);
echo $impact;
And you probably really want:
$impact = $e->find('.impact span', 0)->class;
Read the simple html dom documentation if you don't understand why.
I want to get the child element with specific class form html I have manage to find the element using tag name but can't figureout how can I get the child emlement with specific class?
Here is my CODE:
<?php
$html = file_get_contents('myfileurl'); //get the html returned from the following url
$pokemon_doc = new DOMDocument();
libxml_use_internal_errors(TRUE); //disable libxml errors
if (!empty($html)) { //if any html is actually returned
$pokemon_doc->loadHTML($html);
libxml_clear_errors(); //remove errors for yucky html
$pokemon_xpath = new DOMXPath($pokemon_doc);
//get all the h2's with an id
$pokemon_row = $pokemon_xpath->query("//li[#class='content']");
if ($pokemon_row->length > 0) {
foreach ($pokemon_row as $row) {
$title = $row->getElementsByTagName('h3');
foreach ($title as $a) {
echo "Title: ";
echo strip_tags($a->nodeValue). '<br>';
}
$links = $row->getElementsByTagName('a');
foreach ($links as $l) {
echo "Link: ";
echo strip_tags($l->nodeValue). '<br>';
}
$desc = $row->getElementsByTagName('span');
//I tried that but didnt work..... iwant to get the span with class desc
//$desc = $row->query("//span[#class='desc']");
foreach ($desc as $d) {
echo "DESC: ";
echo strip_tags($d->nodeValue) . '<br><br>';
}
// echo $row->nodeValue . "<br/>";
}
}
}
?>
Please let me know if this is a duplicate but I cant find out or you think question is not good or not explaining well please let me know in comments.

I have one php file in which i am displaying data of xml file by this code
<?php
$xml = simplexml_load_file("note.xml") or die("Error: Cannot create object");
foreach($xml->xpath('//agent') as $item) {
$row = simplexml_load_string($item->asXML());
$v = $row->xpath('//id[. ="1"]');
if($v[0]){
print $item->id;
print $item->image;
print $item->name;
print $item->company;
print $item->street;
print $item->city;
print $item->phone;
}
else{
echo 'No records';
}
?>
Now i want to store this displayed data into other pages of my site and i am begginer of php so not expert in session.
and i want to store this detail in session for displaying this data into other pages of my site. for storing this data into session i have tried this code on same page
<?php
session_start();
$name = $_session_['$item->name'];
?>
But thats not help, So please guys can you suggest me where i am wrong.
any suggestion should be appreciable.
Start ur session in first doc.
<?php
session_start();
$xml = simplexml_load_file("note.xml") or die("Error: Cannot create object");
foreach($xml->xpath('//agent') as $item) {
$row = simplexml_load_string($item->asXML());
$v = $row->xpath('//id[. ="1"]');
if($v[0]){
print $item->id;
print $item->image;
print $item->name;
print $item->company;
print $item->street;
print $item->city;
print $item->phone;
}
else{
echo 'No records';
}
$name = $_session['name'][$item->name]; // dont quote ''
?>
http://www.w3schools.com/php/php_sessions.asp
your session code is not valid, you may try this one ;
$name = $_session['name'][$item->name];
What is the right syntax to use xpath to get the contents of all divs with a certain class? i seem to be getting the divs but i don't know how to get their innerHTML.
$url = "http://www.vanityfair.com/politics/2012/10/michael-lewis-profile-barack-obama";
$ctx = stream_context_create(array('http'=> array('timeout' => 10)));
libxml_use_internal_errors(TRUE);
$num = 0;
if($html = #file_get_contents($url,false,$ctx)){
$doc = DOMDocument::loadHTML($html);
$xpath = new DOMXPath($doc);
foreach($xpath->query('//div[#class="page-display"]') as $div){
$num++;
echo "$num. ";
//????
echo "<br/>";
}
echo "<br/>FINISHED";
}else{
echo "FAIL";
}
There is no HTML in the class="page-display" divs - so you're not going to get anything at all.
Do you mean the get class="parbase cn_text"?
foreach($xpath->query('//div[#class="parbase cn_text"]') as $div){
$num++;
echo "$num. ";
//????
echo $div->textContent;
echo "<br/>";
}
Thanks for taking the time to read my post... I'm trying to extract some information from my website using Simple HTML Dom...
I have it reading from the HTML source ok, now I'm just trying to extract the information that I need. I have a feeling I'm going about this in the wrong way... Here's my script...
<?php
include_once('simple_html_dom.php');
// create doctype
$dom = new DOMDocument("1.0");
// display document in browser as plain text
// for readability purposes
//header("Content-Type: text/plain");
// create root element
$xmlProducts = $dom->createElement("products");
$dom->appendChild($xmlProducts);
$html = file_get_html('http://myshop.com/small_houses.html');
$html .= file_get_html('http://myshop.com/medium_houses.html');
$html .= file_get_html('http://myshop.com/large_houses.html');
//Define my variable for later
$product['image'] = '';
$product['title'] = '';
$product['description'] = '';
foreach($html->find('img') as $src){
if (strpos($src->src,"http://myshop.com") === false) {
$src->src = "http://myshop.com/$src->src";
}
$product['image'] = $src->src;
}
foreach($html->find('p[class*=imAlign_left]') as $description){
$product['description'] = $description->innertext;
}
foreach($html->find('span[class*=fc3]') as $title){
$product['title'] = $title->innertext;
}
echo $product['img'];
echo $product['description'];
echo $product['title'];
?>
I put echo's on the end for sake of testing...but I'm not getting anything... Any pointers would be a great HELP!
Thanks

file_get_html() returns a HTMLDom Object, and you cannot concatenate Objects, although HTMLDom have __toString methods when there concatenated there more then lilly corrupt in some way, try the following:
<?php
include_once('simple_html_dom.php');
// create doctype
$dom = new DOMDocument("1.0");
// display document in browser as plain text
// for readability purposes
//header("Content-Type: text/plain");
// create root element
$xmlProducts = $dom->createElement("products");
$dom->appendChild($xmlProducts);
$pages = array(
'http://myshop.com/small_houses.html',
'http://myshop.com/medium_houses.html',
'http://myshop.com/large_houses.html'
)
foreach($pages as $page)
{
$product = array();
$source = file_get_html($page);
foreach($source->find('img') as $src)
{
if (strpos($src->src,"http://myshop.com") === false)
{
$product['image'] = "http://myshop.com/$src->src";
}
}
foreach($source->find('p[class*=imAlign_left]') as $description)
{
$product['description'] = $description->innertext;
}
foreach($source->find('span[class*=fc3]') as $title)
{
$product['title'] = $title->innertext;
}
//debug perposes!
echo "Current Page: " . $page . "\n";
print_r($product);
echo "\n\n\n"; //Clear seperator
}
?>
