XSLT: Avoiding indentation in some nodes - xslt

Question

I have some XSLT that replaces linebreaks with <Break/> tags and it works fine as long as there isn't multiple consecutive linebreaks. I think it's the indent="yes" that's causing problems.
Can it be disabled for some nodes?
Basically nodes with mixed content (text and elements) can not contain any linebreaks.
The input xml:
<?xml version="1.0" encoding="ISO-8859-1"?>
<Account xmlns="http://example.com/account">
<Owner>
<ID>012345789</ID>
<Name>Peter Johnson</Name>
</Owner>
<Notes>
<NoteID>012345789</NoteID>
<Text>This is the description:
Line 1
Line 2
Line 3
Line 4, after double linebreak
Line 5</Text>
</Notes>
</Account>
The XSL:
<?xml version="1.0" encoding="ISO-8859-1"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns="http://example.com/account" version="1.0">
<xsl:output method="xml" version="1.0" encoding="ISO-8859-1" indent="yes"/>
<xsl:template name="replace_sab">
<!-- with string s, replace substring a by string b -->
<!-- s, a and b are parameters determined upon calling -->
<xsl:param name="s" />
<xsl:param name="a" />
<xsl:param name="b" />
<xsl:choose>
<xsl:when test="contains($s,$a)">
<xsl:value-of select="substring-before($s,$a)" />
<xsl:copy-of select="$b" />
<xsl:call-template name="replace_sab">
<xsl:with-param name="s" select="substring-after($s,$a)" />
<xsl:with-param name="a" select="$a" />
<xsl:with-param name="b" select="$b" />
</xsl:call-template>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="$s" />
</xsl:otherwise>
</xsl:choose>
</xsl:template>
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="text()[not(normalize-space())]"/>
<xsl:template match="text()[boolean(normalize-space())]">
<xsl:call-template name="replace_sab">
<xsl:with-param name="s" select="." />
<xsl:with-param name="a" select="'
'" />
<xsl:with-param name="b"><Break/></xsl:with-param>
</xsl:call-template>
</xsl:template>
</xsl:stylesheet>
The output that I get:
<?xml version="1.0" encoding="ISO-8859-1"?>
<Account xmlns="http://example.com/account">
<Owner>
<ID>012345789</ID>
<Name>Peter Johnson</Name>
</Owner>
<Notes>
<NoteID>012345789</NoteID>
<Text>This is the description:<Break/>Line 1<Break/>Line 2<Break/>Line 3<Break/>
<Break/>Line 4, after double linebreak<Break/>Line 5</Text>
</Notes>
</Account>
The output I would like:
<?xml version="1.0" encoding="ISO-8859-1"?>
<Account xmlns="http://example.com/account">
<Owner>
<ID>012345789</ID>
<Name>Peter Johnson</Name>
</Owner>
<Notes>
<NoteID>012345789</NoteID>
<Text>This is the description:<Break/>Line 1<Break/>Line 2<Break/>Line 3<Break/><Break/>Line 4, after double linebreak<Break/>Line 5</Text>

I am using "TIBCO XSLT 1.0" XSLT engine in a Tibco BusinessWorks process.

Answer 1

There's no standard way of doing this.
If you were using Saxon you could use the saxon:suppress-indentation output parameter, which becomes a standard option in XSLT 3.0.
Perhaps you could find a way of inserting the Saxon serializer into your processing pipeline even if you stick with the Tibco XSLT engine.
