Re: Syntax Assistance Needed

Could someone please explain what that means and what the > '.' period means. As it is used in quite a few other lines. > > eg <xsl:when test="item_type[.='user_art']"> The . means "the context node". . != '' means "the value of the context node is not an empty string", or "the context node has some textual content". So label[. != ''] selects the label element child of the context node that has some text inside it (at any level). You can do the same with label[string()] if you want. Since this is in a test, it might be easier to just do: label != '' The path item_type[. = 'user_art'] selects the item_type element whose string value is 'user_art'. Again, since it's in a test, it's easier to do: item_type = 'user_art' Cheers, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
