DOMDocument::loadXML() error

@kattenOct 30.2007

The error

[code] Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]: Opening and ending tag mismatch: p line 1 and div in Entity, line: 8 in /var/www/gkt/includes/class_xmltoolbox.php on line 44

Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]: Opening and ending tag mismatch: root line 1 and p in Entity, line: 10 in /var/www/gkt/includes/class_xmltoolbox.php on line 44

Warning: DOMDocument::loadXML() [function.DOMDocument-loadXML]: Extra content at the end of the document in Entity, line: 10 in /var/www/gkt/includes/class_xmltoolbox.php on line 44

Fatal error: Call to a member function item() on a non-object in /var/www/gkt/includes/class_xmltoolbox.php on line 48 [/code]

The function

[code=php] public function inparse($text) {

// document for parsing text tree $xml = DOMDocument::loadXML(‘<?xml version=”1.0″ encoding=”utf-8″?><root><p>’ . $text . ‘</p></root>’);

// container for loaded tree $tree = $this->createDocumentFragment(); foreach( $xml->childNodes->item(0)->childNodes as $child) { $tree->appendChild( self::importNode($child) ); } // returns parsed tree return $tree; } [/code]

The string passed to the function

[code=html] Personen: ******* har ansökt om att registera sig på gkt.<br /> Användarnamn: Anto<br /> Email konto: *******@hotmail.com<br /> Telephone: *******<br /> Född:20-09-1991<br /> <br /> Activerings link: <br /> Av activerings link: <a href=”http://www.katten.se”>link</a></div><br />

<br /> Vänliga hälsningar bearhardcreations. [/code]

If i remove the link in the string sent to the function it works but i need it to work even if there is html in the string.

@Stephen_PhilbinOct 31.2007 — #I'm pretty sure I've encountered this problem before. The annoying thing is that I can't remember exactly what caused it. All I can offer you is the code I use to do the same job. I'm not sure if my problem was more namespace-related or not, but here's my code anyway.

There's two functions I use; one function is for handling strings as input and the other is for handling files as input. The class they belong to is intended to be instantiated into an object, but you should be able to tweak them so that you can call them statically (at least that's how it looks like you're using the code you've posted so far).

I'm sorry to be so hopeless and vague, but I hope the code will help give you some ideas.

The string handling function is

[code=php]//Take a string and parse it into a document element.
 public function parse_string_into_element( DOMElement $element , $string , $namespace = NULL)
 {
 $fragment_document = new domDocument();
 
  if(is_string($namespace) === TRUE)
  {
   $fragment_document->loadXML('<root xmlns="' . $namespace . '">' . $string . '</root>');
 
  } else {
 
   $fragment_document->loadXML('<root>' . $string . '</root>');
  }
 
  foreach($fragment_document->documentElement->childNodes as $child_node)
  {
   $child_node = $this->importNode($child_node , TRUE);
   $element->appendChild($child_node);
  }
 
  return $document_fragment;
 }[/code]

and the file handling function is

[code=php]//Take a file and return it as a document fragment.
 public function file_to_frag($file)
 {
 $fragment_document = new domDocument();
 $fragment_document->load($_SERVER['DOCUMENT_ROOT'].$file);
 
  $document_fragment = $this->createDocumentFragment();
  $document_fragment->appendChild($this->importNode($fragment_document->documentElement , TRUE));
 
  return $document_fragment;
 }[/code]

@kattenauthorOct 31.2007 — #I get almost the same error with your parse_string_into_element function

@Stephen_PhilbinOct 31.2007 — #Oh I've just noticed that last error you get. the one about the "class_xmltoolbox.php" file.

Is it ok for you to post that file so I can have a look at it please? I have a feeling it may be interfering with the DOMDocument class.

Thanks.
