Question

Trying to create a PDF file based on an XML and a file using XMLSpy.

I’m trying to split a field into two lines based on the field content.

For example, if my varialbe = “John Doe AKA Johnny D”, I want to view it like this :

John Doe

Johnny D

My problem is that I can’t make it work even with all the samples on the net.

Here’s my code :

     <xsl:value-of disable-output-escaping="yes" select="concat(substring-before(//MyField,'AKA'),$newline,substring-after(//MyField,'AKA'))" /> 
  </xsl:when>

So basically, eveytime I find the “AKA” string, I want to break the field into two lines.
So my code, finds the string, create the new variable but still shows in one line.
I’ve tried creating a variable with a blank line, using all kinds of techiniques but still shows in one line.

Any thoughts ?

See my answer here about using a hex entity reference and linefeed-treatment.

Edit

I took your code from the comments and put it in template in a sample XSLT stylesheet. The only thing I changed was:

1. I changed your newline variable to 
.
2. I added linefeed-treatment="preserve" to your fo:block.

Using a dummy XML file and the XSLT stylesheet, I produced an XSL-FO document that when rendered with FOP, produces “John Doe” and “Johnny D” on separate lines.

Here is the XML file:

<doc>
  <MyField>John Doe AKA Johnny D</MyField>
</doc>

Here is the XSLT stylesheet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>

  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*"/>
    </xsl:copy>
  </xsl:template>

  <xsl:template match="/">
    <fo:root>
      <fo:layout-master-set>
        <fo:simple-page-master master-name="my-page" page-width="8.5in" page-height="11in">
          <fo:region-body margin="1in" margin-top="1.5in"/>
        </fo:simple-page-master>
      </fo:layout-master-set>
      <fo:page-sequence master-reference="my-page">
        <fo:flow flow-name="xsl-region-body">
          <xsl:apply-templates/>
        </fo:flow>
      </fo:page-sequence>
    </fo:root>
  </xsl:template>

  <xsl:template match="doc">
    <xsl:variable name="newline" select="'&#xA;'"/>        
    <xsl:variable name="MyVar">
      <xsl:choose>
        <xsl:when test="contains(//MyField,'AKA')">
          <xsl:value-of select="concat(substring-before(//MyField,'AKA'),$newline,substring-after(//MyField,'AKA'))"/>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="//MyField"/>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:variable>
    <fo:block linefeed-treatment="preserve">
      <xsl:value-of select="$MyVar"/>
    </fo:block>
  </xsl:template>

</xsl:stylesheet>

Here is the resulting XSL-FO:

<fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format">
   <fo:layout-master-set>
      <fo:simple-page-master master-name="my-page" page-width="8.5in" page-height="11in">
         <fo:region-body margin="1in" margin-top="1.5in"/>
      </fo:simple-page-master>
   </fo:layout-master-set>
   <fo:page-sequence master-reference="my-page">
      <fo:flow flow-name="xsl-region-body">
         <fo:root>
            <fo:layout-master-set>
               <fo:simple-page-master page-height="11in" page-width="8.5in" master-name="my-page">
                  <fo:region-body margin-top="1.5in" margin="1in"/>
               </fo:simple-page-master>
            </fo:layout-master-set>
            <fo:page-sequence master-reference="my-page">
               <fo:flow flow-name="xsl-region-body">
                  <fo:block linefeed-treatment="preserve">John Doe 
 Johnny D</fo:block>
               </fo:flow>
            </fo:page-sequence>
         </fo:root>
      </fo:flow>
   </fo:page-sequence>
</fo:root>

The PDF is a single 8.5″ x 11″ page with this on it:

John Doe
Johnny D
