Is there any way to have one XSLT 1.0 stylesheet handle situations where the XML input has different namespace declarations?

I set this up for my customer using entities. They have to deal with a changing namespace URI string for each version of a largely-unchanged vocabulary that is given to them by an outside committee.


Every stylesheet fragment pulls in a common set of general entity string declarations with which namespaces are declared. The parameter entity with these general entity declarations is in an ancestral directory of the stylesheet library.

By installing the read-only stylesheet library in two different locations of the file system, and changing the parameter entity file at each location that is "above" the read-only bits, then all of the stylesheets support the new namespace.

By introducing new general entities for legacy constructs as namespaces evolve, each installation of the read-only stylesheet library will support any given version of the namespace.

In this way my customer has a single maintenance effort and a single library checked into the source code control system ... just multiple deployments, one for each version of the namespace the stylesheets need to support.

Is there a simple solution?

This was easily understood my by customer, effectively deployed and has worked well. These are stylesheet libraries with dozens of stylesheet fragments in the import tree, all with zero maintenance for the change of a namespace URI string. It has been very effective.


I hope this helps.
