I have a table that is populated from a SQL database. Most of the data entered will have an ABN which I can use to look up email and name. Some data doesn’t have an ABN, and only has a UID. I don’t want to have to display the UID in the table since its unnecessary 98% of the time, so I want to use an xsl:when to change the name field to the UID if there isn’t a name.

Here is an example of the 2 cases in XML:

    <?xml version="1.0" encoding="UTF-8"?>
    <CourseData>
      <row batchid="0" courseid="10101" createdon="04/03/2012 01:08PM" datecompleted="1:08 PM" datecompletedDateValue="1333483680000" lastupdatebyabn="999999" lastupdatebyuid="tsmith" lastupdateon="04/03/2012 01:08PM" num="2" respondentabn="999999" respondentemail="tsmith@test.com" respondentid="1" respondentname="Thomas Smith" respondentuid="tsmith"/>       
      <row batchid="0" courseid="10101" createdon="04/03/2012 01:08PM" datecompleted="1:08 PM" datecompletedDateValue="1333483697000" lastupdatebyabn="" lastupdatebyuid="jsmith" lastupdateon="04/03/2012 01:08PM" num="3" respondentabn="" respondentemail="" respondentid="2" respondentname=" " respondentuid="jsmith"/>
    </CourseData>

Here is the XSL I’m using, which obviously isn’t working.

    <xsl:choose>
      <xsl:when test="row[@respondentabn='']">
        <label datafield="@respondentuid"></label>
      </xsl:when>
      <xsl:otherwise>
        <label datafield="@respondentname"></label>
      </xsl:otherwise></xsl:choose></td>

How can I fix this?

Edit: So after talking to my boss, he said for one I’d need an loop in there for this to work right, but that I really shouldn’t be doing this in the .xsl anyways. I modified my sql that is serving up the data to make that change for me, which in retrospect, I probably should have thought of in the first place.

    You don’t give much indication of the stylesheet so it’s hard to be sure but I’d guess you have something like

    <xsl:for-each select="row">
<xsl:choose>
      <xsl:when test="row[@respondentabn='']">
        <label datafield="@respondentuid"></label>
      </xsl:when>
      <xsl:otherwise>
        <label datafield="@respondentname"></label>
      </xsl:otherwise>
</xsl:choose>
</xsl:for-each>

    or in any event if the current node is such that row[@respondentabn=”] does anything useful it must be the parent of row in which case <label datafield="@respondentuid"> would select attributes of the parent (even if the AVT syntax was corrected).

    So I would guess:

    <xsl:for-each select="row">
<xsl:choose>
      <xsl:when test="string(@respondentabn)">
        <label datafield="{@respondentuid}"></label>
      </xsl:when>
      <xsl:otherwise>
        <label datafield="{@respondentname}"></label>
      </xsl:otherwise>
</xsl:choose>
</xsl:for-each>

    Or, more tersely

    <xsl:for-each select="row">
   <label datafield="{@respondentuid[string(.)]|
                      @respondentname[not(string(../@respondentuid))]}"/>
 </xsl:for-each>
