Question

can i use xpath to set element properties ?

/html/body/form[@id='search']/select[@name='category' and @value='apple' and @type='select-one']

Answer 1

XPath, the XML Path Language, is a query language for selecting nodes from an XML document.

To set the value you can use something like a DOM parser and setAttribute('value', 'foo');

It might help if you actually told us if that returned anything or not. You can use count() to see if it returns anything, if not noticeable.
