[SOLVED] Parsing Assistance Needed With XML Files

[mykel241]

Hello,

 

I need to find all occurances of <root contentId=" in this xml file and then be able to access the value of the content id via an array as needed.

 

Here is sample XML:

 

<webservices ver="1.0">

  <status code="1"/>

  <channel>

    <name>somename</name>

    <shortName>some shortname</shortName>

    <authors>

      <author id="17">Some author</author>

      </authors>

  </channel>

  <messageFlow>

        <title>Some Title</title>

    <link>http://www.somelink.com</link>

    <deliveryDate>2007-07-03 00:00:00.0</deliveryDate>

    <root contentId="291655">

      <numComments>0</numComments>

      <text>Some text</text>

      <tags/>

    </root>

  </messageFlow>

  <messageFlow>

    <title>Some Title</title>

    <link>http://www.somelink.com</link>

    <deliveryDate>2007-07-03 00:00:00.0</deliveryDate>

    <root contentId="291656">

      <numComments>0</numComments>

      <text>Some text</text>

      <tags/>

    </root>

  </messageFlow>

 

If anyone can help I would appreciate it. I would prefer to use regular expressions instead on a xml parser.

<?php
$xml_file = file_get_contents('xmlfile.xml');

$root_split = split("</root>", $xml_file);

foreach ($root_split as $root) {
      if (eregi("\">", $root)) {
           list($ids[]) = split("\">", $root);
      }
}

print_r($ids);

?>

 

 

Also here is my shot at a regex version

 

<?php
$xml_file = file_get_contents('xmlfile.xml');

ereg('<root contentId=\"([0-9]*)\">', $xml_file, $matches);
print_r($matches);
?>

 

I am not very good with Regex, but hopefully the above is correct and works.

Thank you,

 

The Reg Exp version works but only finds the first occurance. I am hoping to find all and then place them into an array so I can access them as needed. Any help is appreciated.

Also if anyone has a better but simple solution I would be willing to see it. I appreciate all your help.

<?php
$xml_file = file_get_contents('xmlfile.xml');

while (true) {
    if (ereg("<root contentId=\"([0-9]*)\">", $xml_file, $matches)) {
         $ids[] = $matches[1]; // I think thats right
         $xml_file = str_replace("<root contentId=\"" . $matches[1] . "\">", "", $xml_file);
    }else {
       break;
   }
}    

print_r($ids);
?>

 

Unsure if that will work, but yea. I thought there was a way that it would return all the results. But hopefully the above works and runs somewhat fast.
