Querying XML data across multiple files
I have XML data in multiple files. I would like to query that data across the documents. Is there any elegant way of doing so?
It depends on what you need to query for. The most widespead XML technology
with query capabilities is XPath. It can be used standalone and also as
part of other XML technologies, most notably XSLT.
The easiest approach would be to use an XPath tool that supports wildcard
specification of filenames. Failing that, a simple batch file or Python
script to iterate through the XML files, invoking an XPath/XSLT processor
would do the trick.
