Modifying Input from another XSL before calling

imshriram · April 30th, 2011, 04:26 AM

Hi, Is it possible for me to modify the input file to a XSL?

To be elaborate, I have written XSLs file to convert a XML file to another. Now, the source doc has been changed cos of which I need to rewrite all my XSL. Instead, is it possible me to call another XSL, which modifies the input and carry on with the usual processing? All this can be done in one processor call?

Saxon has http://www.saxonica.com/documentatio...t-in-chain.xml to chain transformations. So that might meet your requirement of "be done in one processor call".
Alternatives are to add code to your existing stylesheet but to use a mode for the new templates, then first apply them to store the result in a variable, then to apply the original templates to the contents of the variable. With XSLT 1.0 however that needs the use of an extension function like exsl:node-set($variable).

Writing a pipeline of transformations is a good design approach, but in general my advice would be to chain together multiple simple transformations rather than trying to do everything in one call. There are many ways you can run a sequence of transformations written as separate stylesheets, the best way depends on the environment you are in.

Is there any option to do this with Saxon - HE?
