Using document() to check the existance of a file
Subject: Using document() to check the existance of a file From: Mac Schwarz <mcschwar@xxxxxxxxxxxxxxxxxxxx> Date: Wed, 11 Oct 2000 17:34:43 +0200 |
Hi, I'd like to check the existance of an file with the document function. Depending oon this test I want to generate a link: <xsl:choose> <xsl:when test="document('help.xml')"> <a> <xsl:attribute name="href">help.xml</xsl:attribute>[help] </a> </xsl:when> <xsl:otherwise> <a> <xsl:attribute name="href">helpfiles/help.xml</xsl:attribute>[help] </a> </xsl:otherwise> </xsl:choose> The above snippet from my xsl file won't work (and I tried several othe ways also) but it should illustate what I want to achieve. If a file help.xml exists in the same directory as the xml file it should generate a link to this 'help.xml' otherwise it should generate a link to the main help file at helpfiles/help.xml. Any ideas how to use the document function for that task? Or is there another and better way to generate the links? Regards, mac -- Mac Schwarz / AERIA Projekt / Inst. f.
