Evalution Problems

Hello,

I run into problems evaluating the end of a string.
Take the following structure for example:

<stichwort>
	<token xmlns="">Absicht,</token>
	<token xmlns="">böse</token>
	<token xmlns="">1294ff,</token>
	<token xmlns="">1324f,</token>
	<token xmlns="">1331a</token>
	<token xmlns="">1344</token>
	<token xmlns="">1366</token>
</stichwort>

I need to put every string containing numbers into <number> elements.
If there is a number and a comma appears, it should be trimmed.

I wrote a stylesheet for most of the cases, but I think that there must be an easier way to do this task...

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
	<xsl:template match="node()| @*">
		<xsl:copy>
			<xsl:apply-templates select="@* | node()"/>
		</xsl:copy>
	</xsl:template>
	<xsl:template match="keyword">
		<xsl:element name=" keyword ">
			<xsl:apply-templates select="token"/>
		</xsl:element>
	</xsl:template>
	<xsl:template match="token">
		<xsl:choose>
			<xsl:when test="contains(., '-')">
				<number>
					<xsl:choose>
						<xsl:when test="contains(.,',')">
							<xsl:value-of select="substring-before(.,',')"/>
						</xsl:when>
						<xsl:otherwise>
							<xsl:value-of select="."/>
						</xsl:otherwise>
					</xsl:choose>
				</number>
			</xsl:when>
			<xsl:when test="contains(., 'ff,')">
					<xsl:choose>
						<xsl:when test="string(number(substring-before(., 'ff,')))='NaN'">
							<term>
								<xsl:value-of select="substring-before(.,',')"/>
							</term>
						</xsl:when>
						<xsl:otherwise>
							<number>
								<xsl:value-of select="substring-before(.,',')"/>
							</number>
						</xsl:otherwise>
					</xsl:choose>
			</xsl:when>
			<xsl:when test="contains(., 'f,')">
					<xsl:choose>
						<xsl:when test="string(number(substring-before(., 'f,')))='NaN'">
							<term>
								<xsl:value-of select="substring-before(.,',')"/>
							</term>
						</xsl:when>
						<xsl:otherwise>
							<number>
								<xsl:value-of select="substring-before(.,',')"/>
							</number>
						</xsl:otherwise>
					</xsl:choose>
			</xsl:when>
			...

Can you help me?

Wr,
Roman

Sorry about that.  You're right, my question (now) is really about XSLT and
is independent of FO.

Thanks for explaining.  That makes things a bit clearer.

I'm somewhat relieved to hear that what I'm trying to do is "a bit
tricky", as it wasn't at all obvious to me how to proceed.  I have 20+
years of experience programming in procedural languages and certainly
understand things like recursion and iteration, but sometimes it feels
like those years of procedural experience are more a hindrance than a
help, at least as far as XSLT.  ;-)

I've been using xsltproc from libxslt 1.1.5, but that's only because it's
installed on my workstation and has a good reputation.

Searching on the libxslt site, it appears to have at least some support
for the EXSLT extenions, including exsl:node-set.  I'll see how far I
can get with the excellent tips you've provided.

Thanks much!

Tim
