Question

here is the page i want to parse
(the api link i gave is just a dev test so its ok to be public)
http://api.scribd.com/api?method=docs.getList&api_key=2apz5npsqin3cjlbj0s6m

the output im looking for is something like this (for now)

 Doc_id: 29638658
 access_key: key-11fg37gwmer54ssq56l3
 secret_password: 1trinfqri6cnv3gf6rnl
 title: Sample
 description: k
 thumbnail_url: http://i6.scribdassets.com/public/images/uploaded/152418747/xTkjCwQaGf_thumbnail.jpeg
 page_count: 100

ive tried everything i can find on the internet but nothing works good. i have this one script

<?php
$xmlDoc = new DOMDocument();
$xmlDoc->load("http://api.scribd.com/api?method=docs.getList&api_key=2apz5npsqin3cjlbj0s6m");

$x = $xmlDoc->documentElement;
foreach ($x->childNodes AS $item) {
  print $item->nodeName . " = " . $item->nodeValue;
 }



 ?>

its output comes out like this:

#text = 
  resultset = 

      29638658
      key-11fg37gwmer54ssq56l3

Answer 1

I recommend you load the XML data into a new SimpleXmlElement object as this will allow you to run xpath queries against the document.

You will need to do a little research on how it works, but here’s a few pointers…

Execute the xpath like so:

// $xml is a SimpleXMLElement object
$xml = simplexml_load_file('/path/to/file');
$nodes = $xml->xpath('/xpathquery');

A single / represents the root node (in your case rsp). A double slash represents any matching node. For example //title would return all titles. Each result of an xpath query is an array of SimpleXMLElements. You can get data from it like so:

# Untested        
$xml = simplexml_load_file('/path/to/file');
$nodes = $xml->xpath('//result');

foreach ($result as $node) {
    // Print out the value in title
    echo $node->title;
}

// Print out the amount of results
echo $xml->rsp->attributes()->totalResultsAvailable;

The final example with the results numbers may not work, but it is along those lines.
