RE: Converting a Batch File to XML

This kind of thing is very much easier using XSLT 2.0

* use the unparsed-text() function to read the text file

* split it into individual lines using the tokenize() function

* parse each line using xsl:analyze-string

* arrange it into a hierarchical structure using xsl:for-each-group
