Subject: Re: [xsl] how to get total string-length() From: "J.Pietschmann" <j3322ptm@xxxxxxxx> Date: Thu, 01 Aug 2002 21:45:57 +0200 |
Hello all, If I have the following snippet:
<fo:block margin-right="{concat(NNN*1.5),'mm')}"> --------------------------------^^^ <xsl:call-template name="process-nodes"/> <xsl:if test="not(@no-pg-num)"> <fo:leader leader-pattern="dots" leader-pattern-width="2.0mm" leader-alignment="reference-area"/> </xsl:if> <xsl:for-each select="document(concat($libname,'/index.xml'))//index/index-term[@id = $primary]"> <xsl:value-of select="."/><xsl:if test="position() != last()">, </xsl:if> </xsl:for-each> </fo:block>
In the for-each line I grab each index-term that has an id that matches the value in $primary. Thus I could have a line like the index entry..........123, 234, 345
What I want to be able to do is, using the example in the line above, calculate the number of characters in "123, 234, 345" and be able to insert it in the NNN location in the block margin-right location. Obviously I need to figure this out outside/before the block, but howto, that's the question.
This appears to be really easy: put it into a variable and use string-length:
<xsl:variable name="page-list"> <xsl:for-each select="document(concat($libname, '/index.xml'))//index/index-term[@id = $primary]"> <xsl:value-of select="."/><xsl:if test="position() != last()">, </xsl:if> </xsl:for-each> </xsl:variable>
<fo:block margin-right="{concat(string-length($page-list)*1.5),'mm')}"> <xsl:call-template name="process-nodes"/> <xsl:if test="not(@no-pg-num)"> <fo:leader leader-pattern="dots" leader-pattern-width="2.0mm" leader-alignment="reference-area"/> </xsl:if> <xsl:value-of select="$page-list"/> </fo:block>
If you have any markup in the page number list, like fo:basic-links, use xsl:copy-of instead of xsl:value-of.
