php5: question about xpath

[Börni]

Hi,

I couldnt find an answer to my question in the php manual, so i try it
here.
Basically i just want to know if the following is possible.
Suppose you have this xml file:

<root>
<news id="1">
<title>Test</title>
<message>Just a test</message>
</news>
<news id="2">
<title>Test 2</title>
<message>yet another test</message>
</news>
</root>

And then you do the following xpath query:

$nodes = $xpath->query("./news/*", $dom->documentElemen t);

Now, how can i tell how many childs news has? Because $nodes has 4
elements, so one news element could have 4 childs or there are 2 news
elements with 2 childs...
Is there a solution?

<?php

// Get the context nodes
$nodes = $xsl->query("//root/news");
$pos = 0;

while (++$pos < ($nodes->length + 1)) {
$children = $xsl->query(
"descendant::*" ,
$nodes->item($pos - 1)
);
print "//news[$pos] has ";
print $children->length;
print " child elements<br />";
}

?>

Have a look at the count function for xpath.
