 <xsl:template match="String">
<!-- matches elements named 'String' -->
<xsl:apply-templates/>
<!-- processes the children of the element -
- text, other elements, whatever -->
<xsl:if test="not(string(.))">
<!-- passes the test if the string content is empty -->
<xsl:value-of select="'
'"/>
<!-- adds a linefeed character -->
</xsl:if>
</xsl:template>Other tests are possible, but this one is a good one. Note that this will test "true" if your String element contains other elements, but no text. If you want to catch whitespace-only strings as well as zero-length strings, change the test to "not(normalize-space(.))". But note that such whitespace is also passed along by the apply-templates preceding the test. I hope I construed correctly what you meant by "a String element that is empty". This is actually a FAQ, but a hard one to document since the answer is always "it depends". Hasta la vista, Wendell At 04:04 PM 10/23/01, you wrote: How do i say this using xsl: "xsl, if you find a String element that is empty, please add a text element that contains a paragraph return." I am having trouble matching the empty string. ====================================================================== Wendell Piez mailto:wapiez@xxxxxxxxxxxxxxxx Mulberry Technologies, Inc. http://www.mulberrytech.com 17 West Jefferson Street Direct Phone: 301/315-9635 Suite 207 Phone: 301/315-9631 Rockville, MD 20850 Fax: 301/315-8285 ---------------------------------------------------------------------- Mulberry Technologies: A Consultancy Specializing in SGML and XML ====================================================================== XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
