RE: DOM and XML parser
Hi Jeni! yes, it is an interesting idea. but that whouldn't be the same as setting the variable after the match?? like: <xsl:template match="book[@price]"> <xsl:variable name="v" select="@price"/> ... -----Original Message----- From: owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx [mailto:owner-xsl-list@xxxxxxxxxxxxxxxxxxxxxx] On Behalf Of Jeni Tennison Sent: Saturday, August 17, 2002 10:46 AM To: Didier PH Martin Cc: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: Re: DOM and XML parser Hi Didier, > Jeni said: > [Taking the analogy with regexps further, there was an interesting > talk at Extreme which touched on the possibility of getting more > detailed information returned from matching on an XSLT pattern in much > the same way as you might get more detailed information returned from > matching on a regexp, about the submatches within the pattern/regexp.] > > Didier replies: > Gee, sound interesting.

Like, for instance, > some info about the node's contained collection, is that it? The talk was about binary queries in the fxgrep/fxt work at the University of Trier. See http://www.informatik.uni-trier.de/PSI/DocML/ for information, and their paper is at http://www.informatik.uni-trier.de/~aberlea/publications/extreme2002/que ries.pdf. As I understood it, it was a way of assigning variables based on things that were matched during the pattern match. If you have a '%' in front of a location path within an expression then the node-set identified by that location path is assigned to a variable. So for example: <xsl:template match="book[%@price]"> ... </xsl:template> then the current node is the book element (as normal) and the variable $1 (I think) is the price attribute. The rest of the paper got rather technical about querying using forest grammars and things, but I thought this was quite an interesting idea.
