Hi,
How do xsl processors handle xsl:import with regard to (don't really know how to say this) storing xsl:templates in a javax.xml.transform.Templates object?
For sake of example, say I want to xsl:import files that contain 100 xsl:templates. The *importing* file overrides all 100 xsl:templates with new ones. [I want to cache the javax.xml.transform.Templates object in memory for a webapp]. Will the Templates object contain 200 xsl:templates or does it discard the overriden ones?
Take a look at the setURIResolver[1] method on the TransformerFactory class.
These method is called by the XSLT processor when an xsl:import
function in your XSLT is found.
Then, If you write your own URIResolver [2], you can load your xsl file in cache and give it to the XSLT Processor...
TransformerFactory factory = TransformerFactory.newInstance(); factory.setURIResolver(new MyResolver(...));
class MyResolver implements URIResolver { public Source resolve(String href,String base) { // manage your cache and return a Source to the Processor } }
Yes, this is what I currently do, however I use xsl:include for everything thinking (perhaps incorrectly) that I would have a smaller footprint. I mainly want to know if their are some optimizations when using xsl:import that would give me something similar to what I am doing with the resolver/xsl:include strategy.
