Re:  __LINE__ equivalent in XSTL
As Ken said the XSLT processor can have line number information.

An XPath expression for a given stylesheet's nodes can be considered
as an equivalent of "line number".

Please see Oliver Becker's solution on getting trace output for XSLT:

Saxon extension "saxon:path" might be useful.

Or, if you do not use saxon, this posting of Dimitre on Dave's XSL FAQ:

No ... how were you planning to exploit this information in your
transformation?  Perhaps there is something else to help you.

Remember that the input lines of all documents fed into the XSLT
processor are not accessible to an XSLT transformation because the
transformation works on XPath node trees interpreted from those sources.

The XSLT processor, itself, may keep track of input source lines, but
this is an aspect of the processor and not of the W3C specification.

I hope this helps.
