Hi Folks,

I will take the following as an axiom:

Programs written to process XML should be implemented in XSLT.

An XSLT processor is a program that processes XML.

Therefore an XSLT processor should be implemented in XSLT. (As an analogy, many C compilers are implemented in C.)

However, there are no XSLT processors implemented in XSLT.

Instead, XSLT processors are implemented in languages such as Java.

The implication of this state of affairs is this: "For real, manly XML processing don't use XSLT; instead, use Java."

The entire argument appears spurious, so it seems fruitless to try to argue specific points.

Why would anyone even try to do this, even if it were possible, it would be vast amounts of work and would just produce an xslt engine that is slower than the one you started with.

Why are there no XSLT processors implemented in XSLT?

Because it is not a good language for writing a compiler or parser. It is a good language for processing XML.
