[development] trouble destructing xml

[Victor Kane]

For this (and that!) xpath is your friend.

See this example at http://php.net/manual/en/simplexmlelement.xpath.php

$string = <<<XML
<a>
 <b>
  <c>text</c>
  <c>stuff</c>
 </b>
 <d>
  <c>code</c>
 </d>
</a>
XML;

$xml = new SimpleXMLElement($string);

/* Search for <a><b><c> */
$result = $xml->xpath('/a/b/c');

while(list( , $node) = each($result)) {
    echo '/a/b/c: ',$node,"\n";
}

/* Relative paths also work... */
$result = $xml->xpath('b/c');

while(list( , $node) = each($result)) {
    echo 'b/c: ',$node,"\n";
}

I have an xml structure that has

<this>
<that parm1="a" parm2="b" parm3="c">red</that>
<that parm1="e" parm2="f" parm3="d">blue</that>
</this>

I've tried simplexml and a few third-party scripts, one that loads the xml
into an associative array rather than an object, and nothing lets me get at
'red' or 'blue'.  When I use dsm() on the results, for example, in the case
of the object with simplexml I get only one 'that' and do not get its
contents. When I use the script that creates the array, I get both that's,
and all their parms as elements, but not the colors.

I'm curious what else people are using.
