Preserving paragraphs with XSL?

How do you render paragraphs in XML?

Hi all!

I was wondering if anyone here knew how to format paragraphs in XML. I tried to use <xsl:text> but it doesn't seem to work. Is there a way of optimising it so the document already outputs with paragraphs?

Example:

<my_text>
This is some text that should contain paragraphs as well as your usual spaces.
Here is a new paragraph. 
Another paragraph here.</my_text>

What do I have to do in my XSL document to render "my_text" with all it's paragraphs? I was thinking about using a pre tag, but it's not really the solution as it makes it the "same" as source code text, which isn't what I'm looking for.

There must be a way, could anyone help me on this one please?

Regards.

hi,

assuming that you consider a paragraph as some text following one or more linefeeds,
and assuming that you want to output html,
you could do


<?xml version="1.0"?>  
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> 
 <xsl:output method="html" />  
  
 <xsl:template match="/"> 
 <html><head><title>LF to p</title></head> 
 <body> 
 <xsl:variable name="inStr" select="."></xsl:variable>  
 <xsl:variable name="outStr"> 
 <xsl:call-template name="lf2p"> 
 <xsl:with-param name="ckStr" select="$inStr"/>  
 </xsl:call-template> 
 </xsl:variable> 
 <xsl:copy-of select="$outStr"/>  
 </body> 
 </html> 
 </xsl:template>  <xsl:template name="lf2p"> 
 <xsl:param name="ckStr"/>  
 <xsl:choose> 
 <xsl:when test="contains($ckStr,'&#x0a;')"> 
 <xsl:value-of select="substring-before($ckStr,'&#x0a;')"/>  
 <p/>  
 <xsl:call-template name="lf2p"> 
  <xsl:with-param name="ckStr"> 
  <xsl:value-of select="substring-after($ckStr,'&#x0a;')"/>  
  </xsl:with-param> 
 </xsl:call-template> 
 </xsl:when> 
 <xsl:otherwise> 
 <xsl:value-of select="$ckStr"/>  
 </xsl:otherwise> 
 </xsl:choose> 
 </xsl:template> 
</xsl:stylesheet>

(although there might be easier ways..)

Thank you for your reply. It works great but I was wondering if it was possible to render it so that I don't have to build all the HTML around the template and only the p tags are implemented?

Hi,

just change the output method to xml and leave the html-code out. However, if you want to exclude empty lines (which will give <p/> as output) you will have to adapt the code. Also, take care: as this method works with recursion, you may not be able to have big input files.
anyway here is an (untested) example:


  
<?xml version="1.0"?>  
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">  
 <xsl:output method="xml" />  
  
 <xsl:template match="/">  
 <myoutput>  
 <xsl:variable name="inStr" select="."></xsl:variable>  
 <xsl:variable name="outStr">  
 <xsl:call-template name="lf2p">  
 <xsl:with-param name="ckStr" select="$inStr"/>  
 </xsl:call-template>  
 </xsl:variable>  
 <xsl:copy-of select="$outStr"/>  
 </myoutput>  
 </xsl:template>  <xsl:template name="lf2p"> 
<xsl:param name="ckStr"/> 
<xsl:choose> 
<xsl:when test="contains($ckStr,'&#x0a;')"> 
<p> 
<xsl:value-of select="substring-before($ckStr,'&#x0a;')"/> 
</p> 
<xsl:call-template name="lf2p"> 
<xsl:with-param name="ckStr"> 
<xsl:value-of select="substring-after($ckStr,'&#x0a;')"/> 
</xsl:with-param> 
</xsl:call-template> 
</xsl:when> 
<xsl:otherwise> 
<p> 
<xsl:value-of select="$ckStr"/> 
</p> 
</xsl:otherwise> 
</xsl:choose> 
</xsl:template> 
</xsl:stylesheet>
