Hi Tanz, > 1. I would prefer the output to look like this > street, > city, > state, > postalCode I guess that you mean you want to have a carriage return rather than just a space after each comma. You can either write them in literally with: <xsl:value-of select="concat(street, ', ', city, ', ', state, ', ', postalCode)" /> Or you can use a character entity like: <xsl:value-of select="concat(street, ',
', city, ',
', state, ',
', postalCode)" /> There's no difference between the two as far as the XSLT processor is concerned. > 2. Is there way to check that if a "state" does not exist i.e. > <state></state> (as in xml) to return: So you mean that the value of state is an empty string rather than that the element state doesn't exist? You can check whether the value of state is an empty string with: state = '' or: not(string(state)) To get the output that you want, you need to split up the xsl:value-of and insert an xsl:if: <xsl:value-of select="concat(street, ',
', city, ',
')" /> <xsl:if test="string(state)"> <xsl:value-of select="concat(state, ',
')" /> </xsl:if> <xsl:value-of select="postalCode" /> I hope that helps, Jeni --- Jeni Tennison http://www.jenitennison.com/ XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
