I have a need to replace all GUID (or UID consist of 32 character) in an installation project file (xml format). I wrote a xsl which replaces all uid elements with the one I specify in <uid>. Since UID must be unique, I must come up a way to insert individual UID. I can generate the UID in Java code. I am thinking (not sure it's possible) two ways of handling this: one is to generate a list of UID in an xml file, and import each UID to each <uid> element. Second is to invoke the function that returns the UID directly in xsl.
I am new to xsl, so I appreciate your help in this issue. Thanks!
You use the document() function to read the XML (or you can pass it as a parameter to your stylesheet, and then you locate the elements within it using path expressions just as in your primary document.
With the document() function, I was able to retrieve the data from an external xml file. However, It writes all UID with the first GUID. I know that somehow I need to use a loop or some reference to the next element in guid.xml, but just not sure where. could you shine some light?
because you can't use xsl:param here. (If you don't get an error, it's a bug in your XSLT processor). However, what you are trying to do is basically flawed, because XSLT, as a functional programming language, doesn't have updatable variables. You need to think of this as a function: calculate the variable $n as a function of something in your input. It might be as simple as position(), or something more complicated involving xsl:number.
