Parsing xml with php and xpath
- by Hyung Suh
Hey guys,
I'm trying to parse an xml file to return a item with a specific id only, but having trouble
making it work.
here's what I have in php
$xml_str = file_get_contents("test.xml");
$xml = simplexml_load_string($xml_str);
$albid = $_GET['id'];
$nodes = $xml->xpath('//library/book[@id=1]');
foreach($nodes as $node) {
echo $node['title'].'<br/>';
}
First, the php is not returning anything from the xml file.
What would I need to fix to return the data?
Also, how would I enter $albid into the xpath so that the id will be retrieved from the link?
Any pointers in the right direction would be appreciated.
Thanks!
--and here's the sample xml file--
<library>
<book id="1">
<title>PHP and MySQL</title>
<author fname="miguel" lname="alvarez">Miguel Alvarez</author>
</book>
<book id="2">
<title>JAVA 123</title>
<author fname="william" lname="vega">WIlliam Vega</author>
</book>
