I used to have the same problem I think.
Tell me if I'm wrong : what you want is to preserve line breaks on the final
HTML output.
In html, lines breaks in the source are ignored : you need a <br/> element
so that the break can been seen in your browser (only textarea preserve the
source's line breaks ).
Then you need a template which replace every line break characters ("
")
by a <br/> element.
This couple of templates make this. (I don't remembre who I have it from)
<xsl:template name="lf2br">
<!-- import $StringToTransform -->
<xsl:param name="StringToTransform"/>
<xsl:choose>
<!-- string contains linefeed -->
<xsl:when test="contains($StringToTransform,'
')">
<!-- output substring that comes before the
first linefeed -->
<!-- note: use of substring-before() function
means -->
<!-- $StringToTransform will be treated as a
string, -->
<!-- even if it is a node-set or result tree
fragment. -->
<!-- So hopefully $StringToTransform is really
a string! -->
<xsl:value-of
select="substring-before($StringToTransform,'
')"/>
<!-- by putting a 'br' element in the result
tree instead -->
<!-- of the linefeed character, a <br> will be
output at -->
<!-- that point in the HTML
-->
<br/>
<!-- repeat for the remainder of the original
string -->
<xsl:call-template name="lf2br">
<xsl:with-param
name="StringToTransform">
<xsl:value-of
select="substring-after($StringToTransform,'
')"/>
</xsl:with-param>
</xsl:call-template>
</xsl:when>
<!-- string does not contain newline, so just output it
-->
<xsl:otherwise>
<xsl:value-of select="$StringToTransform"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
I defined another template to call like this :
<xsl:call-template name="CopyWithLineBreaks">
<xsl:with-param name="string"
select="some_Xpath"/>
</xsl:call-template>
<xsl:template name="CopyWithLineBreaks">
<xsl:param name="string"/>
<xsl:variable name="Result">
<xsl:call-template name="lf2br">
<xsl:with-param name="StringToTransform"
select="$string"/>
</xsl:call-template>
</xsl:variable>
<xsl:copy-of select="$Result"/>
</xsl:template>
Hope this help !
Matthieu.

forgive my novice ineptitude.
I am working on a project where we would like to preserve line breaks
that are entered into our XML database.
In the root of your XML documents add xml:space="preserve". That should
force the XML parser to keep whitespace.
We are doing our XSL transformations with version 1.
If I use my XSLT to output/display this data into a <textarea>
element, the line breaks found in the database are there when displayed.
If I output to a simple <p> element, the line breaks are gone.
Use a <pre> instead of a <p>. You got me all confused now :-P
