Subject: [xsl] HOW TO CHECK FOR EXISTENCE OF A NODE From: "Mike Rudolph" <mrudolph@xxxxxxx> Date: Fri, 14 Mar 2003 10:54:47 -0600 |
Newbie here. I am looking for the proper element to evaluate the existence of a node in order to suppress the generation of an HTML display 'box' if a particular node does not exist. So, instead of producing a box with a caption of 'HEADER NOTES' when there are no header notes, I would rather not produce the box at all to cut down on the clutter. Here is the code which makes the box and displays any header_notes_text if it exists. For example, <TABLE BORDER="4" WIDTH="100%" VALIGN="TOP" CELLPADDING="5"> <TR> <TD WIDTH="100%" VALIGN="TOP" COLSPAN="2"> <H4 ALIGN="LEFT">HEADER NOTES AREA</H4> <xsl:for-each select="header_notes"> <xsl:value-of select="header_notes_text" /><BR/> </xsl:for-each> </TD> </TR> </TABLE> I tried wrapping the above with xsl:template but got this error: Keyword xsl:template may not be used here. I have not had any ah-ha experiences yet, so I don't see the obvious. ---------- Mike Rudolph - EDI Coordinator Green Bay Packaging Inc.
