Subject: [xsl] Problems incrementing a variable in a <xsl:for-each> From: Carlos Barroso <est-c-barroso@xxxxxxxxxxxxx> Date: Wed, 23 Oct 2002 14:42:19 +0100 |
Hy there. I'm having problems incrementing a variable in a <xsl:for-each> section. Below is the XML document, the stylesheet I used and the output I got. ----------------------- XML file ----------------------- <?xml version='1.0' encoding='ISO-8859-1'?> <!DOCTYPE CLIENTS SYSTEM 'counter.dtd'> <CLIENTS> <CLIENT> <NAME value='xpto'/> <AGE value='10'/> </CLIENT> <CLIENT> <NAME valor='xxx'/> <AGE valor='20'/> </CLIENT> </CLIENTS> ---------------------- First XSL file ---------------------- <?xml version='1.0' encoding='ISO-8859-1'?> <xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'> <xsl:output method='text'/> <xsl:variable name="counter" select="0"/> <xsl:template match='/CLIENTS'> <xsl:for-each select="./CLIENT"> <xsl:variable name="counter" select="1 + $counter"/> <xsl:value-of select="$counter"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> ------------------------- Output in TXT file ------------------------- 11 -------------- // -------------- ------------------------ Second XSL test ------------------------ <?xml version='1.0' encoding='ISO-8859-1'?> <xsl:stylesheet version='1.0' xmlns:xsl='http://www.w3.org/1999/XSL/Transform'> <xsl:output method='text'/> <xsl:variable name="counter" select="0"/> <xsl:template match='/CLIENTS'> <xsl:variable name="counter" select="1 + $counter"/> <xsl:value-of select="$counter"/> <xsl:variable name="counter" select="1 + $counter"/> <xsl:value-of select="$counter"/> </xsl:template> </xsl:stylesheet> ------------------------- Output in TXT file ------------------------- 12 -------------- // -------------- In the second XSL file, the counter procedes as planned. But in the first XSL the counter mantains it's value!? I tried using templates instead of "<xsl:for-each>" but it gives me the same results! I don't know what's wrong. Can someone help me please. This is very weird to me. Thanks a lot. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
