Hi,

I have a HTML search form sitting on a PHP page. I want to search a large xml document for values entered into the HTML form fields. I had planned to pass the form values to an XSL as parameters via PHP and then use XPATH within the XSL to search for node values within the XML document which match the form field values.

However, I can't get it to work with multi valued parameters. e.g. a multiple select box.

Is it possible to pass a multi valued parameter to XSL and if so how do you access the individual parameter values?

Is XSL a good approach to searching big XML documents?

Any help much appreciated,
Thanks

In XSLT 2.0 you could pass the parameters as a sequence of strings. That data type isn't available in 1.0, so you have a choice:

(a) create a little XML document in which the parameter strings are represented as elements, and pass this document as a parameter

(b) concatenate the parameter strings using a separator such as TAB, and then tokenize it within the stylesheet.

Probably (a) is easier and (b) is faster.
