| > XPath/XSLT 2+ also have only a single implementation As far as XPath goes, that's wrong: 1. Saxon (the one you talk about) 2. BaseX (an XQuery 3.1 processor) 3. Xidel (implements many XQuery 3.1 features) 4. eXistdb 5. fonto-xpath (NodeJS) 6. frameless.io (JS, also XSL) And these are the ones, which face the public internet. I think, Microsoft has an 2.x implementation, I am pretty sure, IBM and Oracle do so, as well. Now, as for XSL-T, you are right: the easily available implementations are Saxon, but, as it seems, also frameless.io (which I just found out about a few minutes ago, so I may be wrong). But again, I guess, that big enterprise has their own solutions bundled. |
