[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Inserting global parameter value into xsl:function
 In my XSL I have defined a function that will take a required, top-level parameter (called 'position'), and then feeds this position into a variable (called 'forward') that calls the function ('forwardURL') with the 'postion' parameter as the value that references the value I need. The function is used to return a URL value from the XML doc. That URL should be available for referencing later in the HTML output through the 'forward' global attribute. Whenever I try to invoke the code below, it chokes on data typing issues, saying that it cannot add xs:string to xs:integer. What it is trying to do is take the ($position) reference in the "forward" variable and add it within the function to 1. But it's treating $position as a string, not as an integer passed on as a value. How can I reference $position (or any other variable/parameter) within a select/XPath-esque attribute so that it doesn't treat $position as a literal string? Do I use curly braces, brackets, or what? I'm using Saxon 7.5.1 as servlet, with JDK 1.4.1. Thanks for any help you can give.
