如何在PHP中从XML（快速信息文档）中获取所有子标签

Question

I have problem in code when i parse the XML to Array.it returns some tags and not the complete tags.I want to get all tags inside in soap response.I have xml file.and upload this file.

Here is data.txt file below:

<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="<a rel="nofollow" class="external free" href="http://schemas.xmlsoap.org/soap/envelope/">http://schemas.xmlsoap.org/soap/envelope/</a>"
  xmlns="urn:enterprise.soap.sforce.com">
  <soapenv:Body>
     <retrieveResponse>
        <result xsi:type="sf:sObject">
           <id>123</id>
           <description>description</description>
           <name>testing</imran>
           <cnic>23198398213</cnic>
        </result>
     </retrieveResponse>
  </soapenv:Body>
</soapenv:Envelope>

My PHP code:

<?php
    ini_set("memory_limit", "44879M");
    include("dom.php");
    $xml = str_get_html( file_get_contents("data.txt") );
    $final = array();
    $result = $xml->find("result");
    foreach($result as $r){

        $tag = $r->children();
        $one = array();
        foreach($tag as $child){
            $tag = $child->tag;
            echo "<pre>";
            print_r($tag); echo "<br>";

            if( stristr($tag, ":") ){
                list($com, $tag) = explode(":", $tag);

            }
            $one[$tag]  =  trim(strip_tags($child->innertext));
        }
        $final[] = $one;
        //print_r($final); exit;
    }
    print_r($final);
?>

My output:

id
description
name
Array
(
    [0] => Array
        (
            [id] => 123
            [description] => description
            [name] => testing             23198398213
        )
)

My expected output should:

id
description
name
cnic
Array
(
    [0] => Array
        (
            [id] => 123
            [description] => description
            [name] => testing   
            [cnic] =>   23198398213       
        )
)

Please help

Thanks in Advance.

The problem is caused by simple_html_dom trying to correct your XML. There are a few issues with it and if they were resolved, you could load it much more efficiently with either DOMDocument or SimpleXML.

If you corrected the element

<name>testing</imran>

as the html parser is trying to correct the structure, it's taking this and the <cnic> element as one piece of data. Change this to

<name>testing</name>

and your output changes to...

<pre>id<br><pre>description<br><pre>name<br><pre>cnic<br>Array
(
    [0] => Array
        (
            [id] => 123
            [description] => description
            [name] => testing
            [cnic] => 23198398213
        )

)

If you corrected your XML, then you could do the following (XML included)...

$data = <<< XML
<?xml version="1.0" encoding="utf-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"
    xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
    xmlns="urn:enterprise.soap.sforce.com">
  <soapenv:Body>
     <retrieveResponse>
        <result xsi:type="sf:sObject">
           <id>123</id>
           <description>description</description>
           <name>testing</name>
           <cnic>23198398213</cnic>
        </result>
     </retrieveResponse>
  </soapenv:Body>
</soapenv:Envelope>
XML;

$xml = new SimpleXMLElement($data);
$xml->registerXPathNamespace("def", "urn:enterprise.soap.sforce.com");
$result = $xml->xpath("//def:result");
$final = array();
foreach ( $result[0]->children() as $element ) {
    $final [ $element->getName() ] = (string)$element;
}
print_r($final);
