XML node extraction Problems

When the existing PHP code outputs an XML node, it can only output the content of the first node with the same name & quot; 100 & quot;. How can I output the content of all nodes? For the existing code, see: & amp; lt ;? Php * $ xmlstring original content: ** & amp; lt ;? XML version & quot; 1.0 & quot ;? & Amp; gt; & amp; lt ;! DOCTYPEGetUserInfo & amp; gt;-& amp ;... when the existing PHP code outputs an XML node, only the content of the first node with the same name "100" can be output ". how can I output the content of all nodes?

For the existing code, see:
/* $ Xmlstring original content:
**

-
Id * cn
100
101
102
103
105
**
*/

$ Xmldoc = new DOMDocument ();
$ Xmldoc-> loadXML ($ xmlstring );
$ Users = $ xmldoc-> getElementsByTagName ('getuserinfo ');
Foreach ($ users as $ user ){
$ Html. = 'outputcustomer: '. get_txt ($ user, 'customer ').'
';
$ Html. = 'outputgeo: '. get_txt ($ user, 'geocallcli ').'
';
}
Echo $ html;

Function get_txt ($ parent, $ name ){
$ Nodes = $ parent-> getElementsByTagName ($ name );
Return $ nodes-> item (0)-> nodeValue;
}
?>

Last line of code

return $nodes->item(0)->nodeValue;

Because only item (0) is returned)
So only one 100
You only need to check the length of $ nodes and output it cyclically.
Code

  
  
   
    id*cn
   
   
    100
   
   
    101
   
   
    102
   
   
    103
   
   
    105

Code example. Thank you!
