[xep-support] How to preserve a preformatted block of text in the FO table

[Tang Hong - Developer]

We are trying to generate a FO table with a preformatted block of text in one 
cell. We can generate the preformatted text in a FO block. But when we put the 
block in a table cell we lose the preformatting.

Incoming text has preformatted blocks enclosed between "/<PRE/>" and "/</PRE/>". 
They will be replaced with genuine <PRE> and </PRE> tags later. We generate 
preformatted text by putting everything between "/<PRE/>" and "/</PRE/>" in a FO 
block. The block is set in Courier font with whitespace and linefeeds preserved.

Here is the xsl code we use. It works when we generate a FO block that is not in 
a FO cell. It does not preserve whitespace and linefeeds when the block is in a 
FO cell. Is there some way we can preserve whitespace and linefeeds in a table 
cell?

<xsl:param name="analysis"><xsl:value-of select="@analysis" /></xsl:param>
  <xsl:choose>
    <xsl:when test="substring($analysis, 1, 7)='/&#060;PRE/&#062;'">
        <fo:block space-after.optimum="1pt" space-before.optimum="2pt"
            font-family="Courier" font-size="9pt" font-weight="normal"
            linefeed-treatment="preserve" space-treatment="preserve"
            white-space-collapse="false">
            <xsl:value-of select="substring-before(substring($analysis, 8), 		
	    '/&#060;/PRE/&#062;')" />
         </fo:block>
         <fo:block font-family="Helvetica" space-after.optimum="6pt" 			
	      space-before.optimum="0pt"
              font-size="11pt" font-weight="normal"
              linefeed-treatment="preserve" space-treatment="preserve">
             <xsl:value-of 
select="substring(substring-after(substring($analysis, 10), '/&#060;/PRE/&#062;
'), 2)" />
          </fo:block>
          </xsl:when>
          <xsl:otherwise>
          <fo:block font-family="Helvetica" space-after.optimum="6pt" 
space-before.optimum="2pt"
              font-size="11pt" font-weight="normal"
              linefeed-treatment="preserve" space-treatment="preserve">
             <xsl:value-of select="$analysis" />
          </fo:block>
          </xsl:otherwise>
          </xsl:choose>
