Subject: [xsl] xsl:for-each...iteration question From: "Paul Coletti" <pcoletti@xxxxxxxxxx> Date: Tue, 19 Apr 2005 18:19:29 +0200 |
This has been answered before I'm sure but doing a relevant search in the archives is tricky. I've an input doc containing a number of modify-attr elements <modify> <modify-attr attr-name = "abc"/> <modify-attr attr-name = "123"/> <modify-attr attr-name = "789"/> </modify> I have another document containing a list of prohibited attributes. <exclude-list> <exclude-attr>123</exclude-attr> </exclude-list> I want to iterate over my input doc and copy all those modify-attr elements that are NOT in the exclude list to the output. <xsl:template match="modify/modify-attr"> <xsl:variable name="currentAttr" select="@attr-name"/> <xsl:variable name="currentNode" select="."/> <xsl:for-each select="document('excludedoc')/exclude-list/exclude-attr"> <xsl:when test="$currentAttr=."> <xsl:message>Exclude</xsl:message> </xsl:when> <xsl:otherwise> <xsl:copy-of select="$currentNode"/> </xsl:otherwise> </xsl:for-each> </xsl:template> Obvisouly, this is flawed, I get multiple modify-attr elements copied to the output because I cannot see a way of ensuring the for-each only copies a permitted node once and once only. I've a feeling this is approaching the problem from the wrong way....
