Re: Problem with xslt recursion
> [number($Index)] you would have been better to have kept Index as a number rather than forcing it back to a number. ie don't do this: <xsl:with-param name="Index"><xsl:value-of select="$Index+1"/></xsl:with-param> do this <xsl:with-param name="Index" select="$Index+1"/> Never use xsl:variable with content instead of a select attribute unless you intend to do that. It is quite expensive. You are starting with a number then generating a text node with the string value of that number, placing that in a root node, making a result tree fragment of that, and then converting the whole thing back to a number with number(). The purpose is solved but i want to know if it is the right thing to do.... Impossible to say given your description, but it seems unlikely that you need recursion at all. As I said in my reply your stated aim of concatenating the text can be done with a single line: <xsl:copy-of select="Type/text()"/> <xsl:variable name="fullpath" select="concat('/a/b/',$path)"/> This is a FAQ Xpaths are not strings, they are part of the syntax of the language. In C or Java or most other programming languages, if you had a variable x with value 2 and the string "x+2" it wouldn't be trivial to get the value 4: you'd have to write a parser to parse the string and access the referenced constructs. It is the same in XPath, if you have a string that looks like an XPath then this is no use to you unless you have an Xpath parser that is callable at run time. Some systems do have such an extension, eg saxon:evaluate but it is not a standard part of the language. In simple cases such as your first <xsl:variable name="path">c</xsl:variable> (which would be better as <xsl:variable name="path" select="'c'"/> ) <!-- Now i am trying to access the dynamic path a/b/c you can do /a/b/*[name()=$path] This really is a FAQ see the faq that is linked from the home page of this list.
