Wow!! Mike, I can't believe you responded to my question. I have your book (just purchased two weeks ago) and to have you reply to my question has me star struck! So, many thanks for responding! Anyway...my problem stems from an XML document that has 3 attributes with 3 values. My ultimate goal is to display the output in a table using HTML. Now, at various points throughout my XML document these same attributes and values appear; thus, my output in HTML will have multiple tables. But, at some points in the XML document, the attributes have no value at all (ie, Abstract=" " or Name=" "). They way I have my HTML is like the following: <TABLE border="1"> <TR> <xsl:for-each select="ATTRIBUTE"> <TD> <TABLE border="1"> <TR> <TH> <xsl:value-of select="NAME"/> </TH> </TR> <TR> <TD> <xsl:value-of select="VALUE"/> </TD> </TR> </TABLE> </TD> </xsl:for-each> </TR> </TABLE> The output is as follows: Row1: Name Default Abstract Row2: ProductId true Now, what I want to happen is to add some XSLT language that would be able to not print, say, a Default column if, and only if, there is no value associated it to it. If it does find it, then it prints it. Does that makes sense? So, in the above scenario, the Default column would not be seen in the browser. I will try to test what you provided me here. I will also look in your book for additional information. Many thanks, Mike!!!

Normally <xsl:value-of select="Description"/> will achieve the required effect. Or try something like: <xsl:choose> <xsl:when test="Description">... do something ...</xsl:when> <xsl:otherwise><!-- do nothing --></xsl:otherwise> </xsl:choose> Mike Kay XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
