Re: [xsl] normalize-space() except ...

To All,
When I don't want normalize-space() in a mixed content text flow I use this
function to preserve any leading and trailing space which the
normalize-space() would eliminate
<!--
=============================================================================
-->
<!-- this function is a single parm which is the text value to be cleanup NOT
normalized -->
<!-- leading and trailing spaces are preserved but runs of white space
characters become a single space -->
<!-- This means that tab, 0A and 0D should vanish. -->
<xsl:functionname="tb:string-cleanup">
<xsl:paramname="string"/>
<xsl:variablename="string-to-output">
<xsl:analyze-stringselect="$string"regex="\s+">
<xsl:matching-substring>
<xsl:text> </xsl:text>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-ofselect="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:variable>
<xsl:iftest="$DEBUG-string-cleanup = 'yes' and $string != $string-to-output">
<xsl:message>
<xsl:text>STRING CHANGED FROM [</xsl:text>
<xsl:copy-ofselect="$string"/>

<xsl:copy-ofselect="$string-to-output"/>
<xsl:text>]</xsl:text>
</xsl:message>
</xsl:if>
<xsl:copy-ofselect="$string-to-output"/>
</xsl:function>

My algorithm (for which I canbt find code right now, but may rewrite
later) is to concatenate the following:

1) If the text node starts with a space, a single space.

2) The results of normalize-space().

3) If the text node ends with a space, a single space.
