XML parsing class, possible scope problem?

[delirium]

I'm working on a class to parse XML and am having a frustrating time figuring out why the value of one of my class variables is disappearing.  Here is a class I made to test the problem:

 

class Parser {
var $insideq;
var $tag="";
var $qtext="";
var $num=0;


function startElement($parser,$tagname,$attr) {
$this->tag=$tagname;
echo $tagname . "<br>";
echo $this->qtext;
}


function characterData($parser, $data) {
if ($this->tag=="TEXT") {
$this->qtext=$data;
$this->num=1;
} 
echo $this->qtext;
echo $this->num;

}

function endElement($parser,$tagname) {
if ($tagname=="SELECTONE") {
echo $this->qtext;

}
echo "\\" . $tagname . "<br>";

}

}

 

Here is the XML that is being used to test:

<SELECTONE>
<TEXT>Testing text</TEXT>
<punch></punch>
<PUNCH></PUNCH>
<PUNCH></PUNCH>
</SELECTONE>

 

And the output is as follows:

 

SELECTONE

0TEXT

Testing text1Testing text\TEXT

1PUNCH

\PUNCH

1PUNCH

\PUNCH

1PUNCH

\PUNCH

1 \SELECTONE

 

 

The program should be printing the value of $qtext ("Testing text") at the closing of each tag.  Instead, it only seems to be storing the string for the duration of the Text tag and then prints blank for the rest of the tags.  It has no problem remembering the value of $num, which leads me to believe there's something quirky about the $data variable in the characterData function (which is a character data handler function used like this - xml_set_character_data_handler($xml_parser, "characterData");

 

I'm clearly screwing something up, but I'm completely baffled as to what it is.

bump.  anyone have an idea of what could be happening here?

One last bump before I give up.  Am I doing anything fundamentally wrong here?
