"tag", do you mean an attribute of the current element ?
I would write
test="@sendfax='Y'"

I don't think I ever used a syntax like ./
I used ../
or nothing
but can't understand what this is meant for (of course this can simply 
be a syntax I'm not used to).

Re: Using CHOOSE to control image in region-body

Hi, Jeff,

I whipped up a small test to show how to solve your problem. Here's the 
contents of the (very simple) input XML file:

<test>
  <send-fax>Y</send-fax>
</test>

Here's the (also very simple XSL file):

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xsl:stylesheet version="2.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="test">
    <xsl:choose>
      <xsl:when test="send-fax = 'Y'">
        <xsl:message>Found it</xsl:message>
      </xsl:when>
      <xsl:otherwise>
        <xsl:message>No joy</xsl:message>
      </xsl:otherwise>
    </xsl:choose>
  </xsl:template>

</xsl:stylesheet>

When I run that XML file against that XSL file, I get "found it" on my 
command line.

I bet you can extrapolate from there how to get the XSL-FO content you want. 
If not, let me know and I'll try to help further.

When the tag "send-fax" does not exist print the lilly, when send-fax=Y,
print the pebble.  I always get the Lilly.  Can you determine why?

<xsl:choose>
  <xsl:when test="./send-fax='Y'">
       <!--   region-before means region before the body(top 1/3 of
folio   -->
       <fo:region-before extent="3.0in"
                    background-repeat="no-repeat"
                    margin-top=".5in"
                    background-image="url('java/images/Pebble.jpg')"
                    background-position-vertical="bottom"
                    display-align="after" />
  </xsl:when>
  <xsl:otherwise>
      <fo:region-before extent="3.0in"
                    background-repeat="no-repeat"
                    margin-top=".5in"
                    background-image="url('java/images/Lilly.jpg')"
                    background-position-vertical="bottom"
                    display-align="after" />
  </xsl:otherwise>
</xsl:choose>

RE: Using CHOOSE to control image in region-body

Hi,

If you read  "<send-fax>Y</send-fax>", it is possible that there are some extra invisible charaters.
If you want, you can investigate with string-length() and if >1, try to determine (then discard)
unexpected characters.

However, I can imagine 2 simple solutions that should help:
First solution should be to use normalize-space() function, like this:
<xsl:when test="normalize-space(send-fax)='Y'">...

Another solution consists in using contains() function:
<xsl:when test="contains(send-fax,'Y')">...

Just for curiosity, what XSLT engine do you use?

HTH,
Pascal
