Subject: RE: [xsl] How to select an attribute on the current node or its anchestor From: "Trevor Nicholls" <trevor@xxxxxxxxxxxxxxxxxx> Date: Fri, 15 Apr 2011 18:40:36 +1200 |
XSL 1: <xsl:value-of select="ancestor-or-self::*[@data != ''][1]/@data" /> In XSL 2 you can construct a sequence of data attribute values which would allow you to get the max() or min() value - that's not your requirement but it might be a useful extension of it: <xsl:value-of select="(ancestor-or-self::*/@data[. != ''])[last()]" /> Cheers T -----Original Message----- From: Philipp Kursawe [mailto:phil.kursawe@xxxxxxxxx] Sent: Friday, 15 April 2011 6:06 p.m. To: xsl-list@xxxxxxxxxxxxxxxxxxxxxx Subject: [xsl] How to select an attribute on the current node or its anchestor Hello, given the following xml: <node data="foo"> <text id="1" data="bar"/> <text id="2"/> </node> I would like to know the XPath expression to select @data which results in "bar" for @id=1 and "foo" for @id=2. The general idea is to search for the attribute in the anchestor if the current node does not contain the attribute all the way up to the root node. Thanks for your help! Phil
