[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] this script converts an instance path to an RNG path
 The input param "fragment" might be something like "/resume/header/contact and then output will be something like "//*[@name='resume']//*[@name='header']//*[@name='contact']/*". You would then call dyn:evaluate() in EXSLT (or whatever equivalent you have) on the resulting string to turn it into a genuine XPath. Comments welcome as always. <!-- Converts an instance path to an RNG path --> <xsl:template name="inst2rngPath"> <xsl:param name="fragment"/> <xsl:choose> <xsl:when test="starts-with($fragment, '/')"> <!-- strip beginning / --> <xsl:call-template name="inst2rngPath"> <xsl:with-param name="fragment" select="substring-after($fragment, '/')"/> </xsl:call-template> </xsl:when><xsl:otherwise> <xsl:text>//*[@name='</xsl:text> <xsl:choose><xsl:when test="substring-before($fragment, '/')"> <xsl:value-of select="substring-before($fragment, '/')"/> </xsl:when><xsl:otherwise> <xsl:value-of select="$fragment"/> </xsl:otherwise></xsl:choose> <xsl:text>']</xsl:text> <xsl:choose> <xsl:when test="contains($fragment, '/')"> <!-- recursive step --> <xsl:call-template name="inst2rngPath"> <xsl:with-param name="fragment" select="substring-after($fragment, '/')"/> </xsl:call-template> </xsl:when><xsl:otherwise> <!-- default step --> <xsl:text>/*</xsl:text> </xsl:otherwise> </xsl:choose> </xsl:otherwise> </xsl:choose> </xsl:template> simon -- www.simonwoodside.com -- 99% Devil, 1% Angel XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
