I am trying to display the data of a xml parsed page which i get from a external source. which i got passing through some parameters like this:-
http://www.somewebsite.com/phpfile.php?vendor_key=xxx&checkin=2012-11-02&checkout=2012-11-05&city_id=5&guests=3
when i pass this parameters i got an xml result. now i want to display that xml data in a designer way on my webpage. so how can i do so. i am new to xml so dont know what this technology called if any body can tell me what this called so that can also help me.
Take a look at simplexml_load_string.
You can use curl or file_get_contents function to make HTTP request. Then after you can use DOM or SimpleXML to parse the response (XML) of requested URL.
If u have already XMl then try
echo $xml->asXML();
A full example
<?php
$curl = curl_init();
curl_setopt ($curl, CURLOPT_URL, 'http://rss.news.yahoo.com/rss/topstories');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec ($curl);
if ($result === false) {
die('Error fetching data: ' . curl_error($curl));
}
curl_close ($curl);
//we can at this point echo the XML if you want
//echo $result;
//parse xml string into SimpleXML objects
$xml = simplexml_load_string($result);
if ($xml === false) {
die('Error parsing XML');
}
//now we can loop through the xml structure
foreach ($xml->channel->item as $item) {
print $item->title;
}

[![enter image description here][1]][1]I am trying to get the some tag value but it's showing some error.
Below is the code, please suggest some solution.
This is the method i used for httpGet request.
function httpGet($result15)
{
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$result15);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
$output=curl_exec($ch);
curl_close($ch);
return $output;
}
$result15= httpGet("https://www.googleapis.com/customsearch/v1?key=API_KEY&cx=003255er&q=cancer&num=1&alt=atom");//new cse
echo $result15;
$xml = new DOMDocument();
$xml->loadXML($result15);
foreach( $xml->entry as $entry )
{
echo "URL=".(string)$entry->id.PHP_EOL;
echo "Summary=".(string)$entry->summary.PHP_EOL;
}
You might find the curl request is failing. You need to do a couple of things...
function httpGet($result15)
{
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,$result15);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // Add this
$output=curl_exec($ch);
// If this fails, output error.
if ($output === FALSE) {
echo curl_error($ch);
// Not sure what you want to do, but 'exit' will work for now
exit();
}
curl_close($ch);
return $output;
}
This will display an error if the curl request fails. You will need to decide how your going to cope with this. You could return false, and then in your code further down, check this before trying to load it as XML. The code above just stops on errors.
Your next piece of code seems to mix SimpleXML and DOMDocument, you can use SimpleXML if the document structure is fairly straight forward...
$xml = simplexml_load_string($result15);
foreach( $xml->entry as $entry )
{
I want to get the whole element <article> which represents 1 listing but it doesn't work. Can someone help me please?
containing the image + title + it's link + description
<?php
$url = 'http://www.polkmugshot.com/';
$content = file_get_contents($url);
$first_step = explode( '<article>' , $content );
$second_step = explode("</article>" , $first_step[3] );
echo $second_step[0];
?>
You should definitely be using curl for this type of requests.
function curl_download($url){
// is cURL installed?
if (!function_exists('curl_init')){
die('cURL is not installed!');
}
$ch = curl_init();
// URL to download
curl_setopt($ch, CURLOPT_URL, $url);
// User agent
curl_setopt($ch, CURLOPT_USERAGENT, "Set your user agent here...");
// Include header in result? (0 = yes, 1 = no)
curl_setopt($ch, CURLOPT_HEADER, 0);
// Should cURL return or print out the data? (true = retu rn, false = print)
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Timeout in seconds
curl_setopt($ch, CURLOPT_TIMEOUT, 10);
// Download the given URL, and return output
$output = curl_exec($ch);
// Close the cURL resource, and free system resources
curl_close($ch);
return $output;
}
for best results for your question. Combine it with HTML Dom Parser
use it like:
// Find all images
foreach($output->find('img') as $element)
echo $element->src . '<br>';
// Find all links
foreach($output->find('a') as $element)
echo $element->href . '<br>';
Good Luck!
I'm not sure I get you right, But I guess you need a PHP DOM Parser. I suggest this one (This is a great PHP library to parser HTML codes)
Also you can get whole HTML code like this:
$url = 'http://www.polkmugshot.com/';
$html = file_get_html($url);
echo $html;
Probably a better way would be to parse the document and run some xpath queries over it afterwards, like so:
$url = 'http://www.polkmugshot.com/';
$xml = simplexml_load_file($url);
$articles = $xml->xpath("//articles");
foreach ($articles as $article) {
// do sth. useful here
}
Read about SimpleXML here.
extract the articles with DOMDocument. working example:
<?php
$url = 'http://www.polkmugshot.com/';
$content = file_get_contents($url);
$domd=#DOMDocument::loadHTML($content);
foreach($domd->getElementsByTagName("article") as $article){
var_dump($domd->saveHTML($article));
}
and as pointed out by #Guns , you'd better use curl, for several reasons:
1: file_get_contents will fail if allow_url_fopen is not set to true in php.ini
2: until php 5.5.0 (somewhere around there), file_get_contents kept reading from the connection until the connection was actually closed, which for many servers can be many seconds after all content is sent, while curl will only read until it reaches content-length HTTP header, which makes for much faster transfers (luckily this was fixed)
3: curl supports gzip and deflate compressed transfers, which again, makes for much faster transfer (when content is compressible, such as html), while file_get_contents will always transfer plain
i got a url like this one http://somedomain.com/frieventexport.php and the content of this url is a plain XML structure if I check out the source-code of the site:
How can I parse this URL and use it in PHP?
This script gives me an error… "Error loading XML".
<?php
$xml_url = "http://somedomain.com/frieventexport.php";
if (($response_xml_data = file_get_contents($xml_url))===false){
echo "Error fetching XML\n";
} else {
libxml_use_internal_errors(true);
$data = simplexml_load_string($response_xml_data);
if (!$data) {
echo "Error loading XML\n";
foreach(libxml_get_errors() as $error) {
echo "\t", $error->message;
}
} else {
print_r($data);
}
}
?>
One of the best options in my opinion is to use CURL to get the raw XML data from the url:
$curl = curl_init();
curl_setopt( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt( $curl, CURLOPT_URL, "http://somedomain.com/frieventexport.php" );
$xml = curl_exec( $curl );
curl_close( $curl );
You can then use DOMDocument to parse the xml:
$document = new DOMDocument;
$document->loadXML( $xml );
I would also recommend using <![CDATA[]> tags in your XML. Please read the following:
What does <![CDATA[]]> in XML mean?
CDATA Sections in XML
More information about DOMDocument and usage
PHP.net DOMDocument documentation
W3Schools DOMDocument example
file_get_contents() is usually disabled if this is shared hosting, if not you can set allow_url_fopen in php.ini (however beware of the security risks). You can check the setting of this using php_info() or var_dump(ini_get('allow_url_fopen')) to show if it's allowed or not.
If you cannot do the above, you can use CURL to fetch external content
Try the following:
$url = 'xml-file.xml';
$xml = simplexml_load_file($url);
print_r($xml);
Try this :
$livescore_data = new SimpleXMLElement($file);
i just want to get the name of 'channel' tag i.e. CHANNEL...the script works fine when i use it to parse the rss from Google..............but when i use it for some other provider it gives an output '#text' instead of giving 'channel' which is the intended output.......the following is my script plz help me out.
$url = 'http://ibnlive.in.com/ibnrss/rss/sports/cricket.xml';
$get = perform_curl($url);
$xml = new DOMDocument();
$xml -> loadXML($get['remote_content']);
$fetch = $xml -> documentElement;
$gettitle = $fetch -> firstChild -> nodeName;
echo $gettitle;
function perform_curl($rss_feed_provider_url){
$url = $rss_feed_provider_url;
$curl_handle = curl_init();
// Do we have a cURL session?
if ($curl_handle) {
// Set the required CURL options that we need.
// Set the URL option.
curl_setopt($curl_handle, CURLOPT_URL, $url);
// Set the HEADER option. We don't want the HTTP headers in the output.
curl_setopt($curl_handle, CURLOPT_HEADER, false);
// Set the FOLLOWLOCATION option. We will follow if location header is present.
curl_setopt($curl_handle, CURLOPT_FOLLOWLOCATION, true);
// Instead of using WRITEFUNCTION callbacks, we are going to receive the remote contents as a return value for the curl_exec function.
curl_setopt($curl_handle, CURLOPT_RETURNTRANSFER, true);
// Try to fetch the remote URL contents.
// This function will block until the contents are received.
$remote_contents = curl_exec($curl_handle);
// Do the cleanup of CURL.
curl_close($curl_handle);
$remote_contents = utf8_encode($remote_contents);
$handle = #simplexml_load_string($remote_contents);
$return_result = array();
if(is_object($handle)){
$return_result['handle'] = true;
$return_result['remote_content'] = $remote_contents;
return $return_result;
}
else{
$return_result['handle'] = false;
$return_result['content_error'] = 'INVALID RSS SOURCE, PLEASE CHECK IF THE SOURCE IS A VALID XML DOCUMENT.';
return $return_result;
}
} // End of if ($curl_handle)
else{
$return_result['curl_error'] = 'CURL INITIALIZATION FAILED.';
return false;
}
}
php
it gives an output '#text' instead of giving 'channel' which is the intended output it happens because the $fetch -> firstChild -> nodeType is 3, which is a TEXT_NODE or just some text. You could select channel by
echo $fetch->getElementsByTagName('channel')->item(0)->nodeName;
and
$gettitle = $fetch -> firstChild -> nodeValue;
var_dump($gettitle);
gives you
string(5) "
"
or spaces and a new line symbol which happens to appear between the xml tags due to formatting.
ps: and RSS feed by your link fails validation at http://validator.w3.org/feed/
Take a look at the XML - it's been pretty printed with whitespace so it is being parsed correctly. The first child of the root node is a text node. I'd suggest using SimpleXML if you want an easier time of it, or use XPath queries on your DomDocument to obtain the tags of interest.
Here's how you'd use SimpleXML
$xml = new SimpleXMLElement($get['remote_content']);
print $xml->channel[0]->title;
A remote site is supplying a data structure in a js file.
I can include this file in my page to access the data and display it in my page.
<head>
<script type="text/javascript" src="http://www.example.co.uk/includes/js/data.js"></script>
</head>
Does anyone know how I use PHP to take this data and store in it a database?
You should GET that file directly, via, for example, CURL. Then parse it, if it comes in JSON, you can use json-decode.
Simple example (slightly modified version of code found here):
<?php
$url = "http://www.example.co.uk/includes/js/data.js";
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
...
$output = curl_exec($ch);
$info = curl_getinfo($ch);
if ($output === false || $info['http_code'] != 200) {
$error = "No cURL data returned for $url [". $info['http_code']. "]";
if (curl_error($ch))
$error .= "\n". curl_error($ch);
}
else {
$js_data = json_decode($output);
// 'OK' status; save $class members in the database, or the $output directly,
// depending on what you want to actually do.
...
}
//Display $error or do something about it
?>
You can grab the file via CURL or some other HTTP downloading library/function. Then, parse the data. If you're lucky, the data is in a JSON format and you can use a PHP function to convert it into a PHP array. Then, iterate through the items in the array, inserting each into your database.
