hi all, the following code works perfect (the xml is loacted at the
bottom of this post):

$doc = new DOMDocument;

// We don't want to bother with white spaces
$doc->preserveWhiteSpace = false;

$doc->Load('/book.xml');

$xpath = new DOMXPath($doc);

$query1 = '//book/title';

$entry1 = $xpath->query($query1);

foreach ($entry1 as $entry) {
echo "Found {$entry->nodeValue}," .
" by {$entry->nodeValue}<br />";
}

however, i don't know how to get a single value.

echo "Found {$entry1->nodeValue};

echo "Found {$entry1[0]->nodeValue};

don't work

i'm trying to use XPath and XML to nail down the value in the
book/title path ("My lists")

what am i doing worng?

tia...

xml:

<?xml version="1.0" encoding="iso-8859-1"?>
<!DOCTYPE book PUBLIC "-//OASIS//DTD DocBook XML V4.1.2//EN"
"http://www.oasis-open.org/docbook/xml/4.1.2/docbookx.dtd" [
