Implementing condition in XPath [duplicate]

Question

I have a XML file

<?xml version="1.0" encoding="UTF-8"?> <xml> <events date="12/12/2010"> <event> <title>JqueryEvent</title> <description> easily </description> </event> </events> <events date="14/12/2011"> <event> <title>automatically onBlur</title> <description> when a date is selected. For an inline calendar, simply attach the datepicker to a div or span. </description> </event> </events> </xml>

And I am using this Xpath to select the nodes

$xml = simplexml_load_file($file); $nodes = $xml->xpath('//xml/events');

It will select all the nodes.I want to select the nodes based on the date.

Specify the date in the xpath expression,

i.e.

$nodes = $xml->xpath('//xml/events[@date="14/12/2011"]');

would select only the last events-node in the example

Use

$xml = simplexml_load_string($xml); $nodes = $xml->xpath('//events[@date="14/12/2011"]'); print_r( $nodes );

to get the event node below the xml node with the specified date and

$xml = simplexml_load_string($xml); $nodes = $xml->xpath('//xml/events[@date]'); print_r( $nodes );

to get all event below the xml node nodes having a date attribute. Likewise, use

$xml = simplexml_load_string($xml); $nodes = $xml->xpath('//events[contains(@date, "2011")]'); print_r( $nodes );

to find all event nodes anywhere in the document with a date attribute containing the string "2011".

On a sidenote, you can use simplexml_load_file to load an XML file directly.
