Subject: RE: [xsl] xsl sort: using element attribute as sort key! From: "Michael Kay" <mike@xxxxxxxxxxxx> Date: Mon, 18 Apr 2005 09:39:45 +0100 |
The value of (df_data/@column = $sort) is a boolean, true or false. So your sorted sequence will contain all the values for which the content of the @column attribute is not equal to the value of the variable $sort, followed by those for which it is equal. I don't like these XML documents in which the elements are called "row" and "column". My instinct would be to first transform it to a document that uses application-oriented tags, for example <person> <name>Value</name> <phone>Value2</phone> </person> and then use that as the input to your "real" transformation. But if you need to, the answer to your question is sort="df_data[@column=$sort]". And it should be order="{$dir}".
