I have a template to insert a <br> for each CR/LF sequence in the data.

I have yet to get this working, although it is a simple process in
theory. When I debug the "break" template, it appears that the processor
is unable to see the CR LF, although a search of the data in a text editor
finds the sequence w/ no problem.

You can't solve it the way you want to.

According to http://www.w3.org/TR/REC-xml/#AVNormalize any literal
linefeed (
) or carriage-return () characters in attributes
are normalized to spaces before an XSLT engine ever sees them, by
a standards-compliant XML parser. So in XSLT you will never see the
linefeeds you are expecting. And for further reference, that same
XML parser will normalize 
 to 
 so you only need to
test for the linefeed in your code. For details see
http://www.w3.org/TR/REC-xml/#sec-line-ends

You have a couple of options at least:
1. Change the emitting logic to send out entities
2. Use Convert-to-XML to parse the input and then send it to your XSLT

Pardon my ignorance - What do you mean by "Convert-to-XML"?

The data is already in XML from the source system.

Even though it is in XML, you could parse it as raw text if you really
care about the line endings, and that's pretty much your only option if
you can't change the input XML (or at least get it out of the attributes.)
But no XSLT engine can see plain line endings in attributes.

See http://www.stylusstudio.com/docs/v62/d_flatfileconversion9.html for
some details on using it.

John,

Your input document is not very well designed.

XML attributes are suppose to hold a small text like a date or an ID.
Attribute value gets also normalized replacing EOL with space when the XML is parsed.

If you have control on your input the best would be having those long text hold by elements.

Prepocessing the raw text to replace EOL with <br/> is not an option
becaue you will end up having not well formed XML (tag inside attribute value)
Unless you replace EOL with some special string liek WIN_EOL then when processing
the XML replace WIN_EOL with <br/>

In XSLT 2 you can create pre-process step like the following

<?xml version='1.0'?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:value-of select="replace(unparsed-text('file:///c:/Temp/Stylus_Test_Cases/RequirementsRaw.xml', 'UTF-8'), '
','WIN_EOL')"/>
</xsl:template>
</xsl:stylesheet>

Then input the result to your XSLT.
Just need change the "break" template

<xsl:template name="break">
<xsl:param name="text" select="."/>
<xsl:choose>
<xsl:when test="contains($text,'WIN_EOL')">
<xsl:value-of select="substring-before($text,'WIN_EOL')"/>
<br/>
<xsl:call-template name="break">
<xsl:with-param name="text" select="substring-after($text,'WIN_EOL')"/>
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$text"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

Hope this helps
Ivan

After some effort, I got the provider to put the text into elements and now it works fine.

Thanks for the insite.
