[xsl] question on paths
Subject: [xsl] question on paths From: Monosij Dutta-Roy <monosij.forums@xxxxxxxxx> Date: Wed, 26 May 2010 18:54:25 -0400 |
Ok will try again. Appreciate all your responses before. I am writing this function: --------------- <xsl:function name="fnc:getPatientRolePath"> B B B <xsl:param name="Version"/> B B B <xsl:choose> B B B B B B <xsl:when test="$Version = '3.0'"> B B B B B B B B B <xsl: select="/n1:Document/n1:recordTarget/n1:patientRole"/> B B B B B B </xsl:when> B B B B B B <xsl:otherwise>UNDEFINED</xsl:otherwise> B B B </xsl:choose> </xsl:function> --------------- I am writing this function so as to create a variable patientRolePath to hold the value: /n1:Document/n1:recordTarget/n1:patientRole. This is because then I can use the variable name patientRolePath and append child nodes and get required values such as: $patientRolePath/id $patientRolePath/lastName $patientRolePath/firstName However this that function I can't seem to write it to return with the path. <xsl: select="/n1:Document/n1:recordTarget/n1:patientRole"/> is not valid HOWEVER <xsl:variable name="patientRole" select="/n1:Document/n1:recordTarget/n1:patientRole"/> written as a statement is valid. But does not return me anything. OR <xsl:value-of select="/n1:Document/n1:recordTarget/n1:patientRole"/> is valid, but don't need the value of - just need the path. --------------- Hope that explains it better? I have written a few other functions so seem to be able to write functions. Maybe it needs to be done with a node test? Also just bought Michael Kay's book so looking forward to it as soon as it reaches here from Amazon. Also does XSLT have 'out' parameters? Or functions only way to achieve this? --------------- Thanks again. monosij
