Subject: Re: [xsl] most efficient way to check for a group of tags? From: David Carlisle <davidc@xxxxxxxxx> Date: Wed, 2 Mar 2005 22:44:25 GMT |
I've got a template that needs to know the if it contains only 1 of a specific group of tags when it's within a "content" tag, and I've got this condition to do this: count(ancestor::content[1]/child::*[self:tag1 or self:tag2 or self:tag3 ....]) = 1 Now I need to check for about 15 different tags; is there a more efficient way to do this sort of check? Usual comment about the T word, XSLT has no access to the tags in a dcument, and given <foo a="b"> stuff</foo> The content of the tags are 'foo a="b"' and 'foo' respectively. ' stuff' is _between_ two tags, not the content of any tag. (tags are not the same thing as elements) probably it would be more efficient to do <xsl:key name="x" match="tag1|tag2|tag3" use="generate-id(..)"/> .... <xsl:if test="key('x',generate-id(ancestor::content[1]))[2]"> there's more than one of them </xsl:if> David ________________________________________________________________________ This e-mail has been scanned for all viruses by Star.
