Hi, In our app, we use libxml2 and we connect XPath variables to our proprietary script language and its variables. I have recently noticed a possible bug with it. To replicate the issue, I have created an xslt. Handling
of variables is a bit grey zone for me, but I think there has to be a bug somewhere in libxml2. First the xslt (note the different bracketing around $array): <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:exsl="http://exslt.org/common"> <xsl:variable name="array_orig"> <item>1234</item> <item>12</item> <item>123</item> <item>1</item> </xsl:variable> <xsl:variable name="array" select="exsl:node-set($array_orig)/item"/> <xsl:template match="/"> <data> <cnt><xsl:value-of select="count($array)"/></cnt> <l1><xsl:value-of select="string-length($array[1])"/></l1> <l2><xsl:value-of select="string-length(($array)[1])"/></l2> <l3><xsl:value-of select="string-length($array[2])"/></l3> <l4><xsl:value-of select="string-length(($array)[2])"/></l4> <test1> <xsl:for-each select="$array[string-length($array[1])]"> <xsl:element name="{name()}"> <xsl:value-of select="."/> </xsl:element> </xsl:for-each> </test1> <test2> <xsl:for-each select="$array[string-length(($array)[1])]"> <xsl:element name="{name()}"> <xsl:value-of select="."/> </xsl:element> </xsl:for-each> </test2> <test3> <xsl:for-each select="$array[string-length($array[2])]"> <xsl:element name="{name()}"> <xsl:value-of select="."/> </xsl:element> </xsl:for-each> </test3> <test4> <xsl:for-each select="$array[string-length(($array)[2])]"> <xsl:element name="{name()}"> <xsl:value-of select="."/> </xsl:element> </xsl:for-each> </test4> </data> </xsl:template> </xsl:stylesheet> Xslproc produces (xml file is not important, you can use any, I have added whitespace): <?xml version="1.0"?> <data xmlns:exsl="http://exslt.org/common"> <cnt>4</cnt> <l1>4</l1> <l2>4</l2> <l3>2</l3> <l4>2</l4> <test1/> <test2> <item>1</item> </test2> <test3/> <test4/> </data> I would expect to have “item” element also in test1, test3 and test4. The string lengths are 4 or 2 (see l1, l2, l3, l4). There are four elements in $array, see “cnt” element. I have tried it with ms xslt and the “item”
elements are there as I would expect. Vojtech |
