Apply XSLT Transform to an already transformed XML

Question

All,

I have an XML file which I transform it using an XSLT document to another XML.

Can I define another set of transformations in the same XSLT file to be

Answer 1

Yes.

I. This XSLT 1.0 transformation:

when applied on this XML document:

 1
 2
 3
 4
 5

produces:

    3
    5
    7
    9
    11

Do note:

1. Two transformations are actually performed, the second is performed on the result of the first.

2. The result of the first transformation is the content of the variable $vrtfPass1.

3. In XSLT 1.0 the type of variables that contain dynamically generated (temporary) XML trees (XML document or XML fragment) is RTF (Result-Tree-Fragment). No XPath operations are possible on an RTF -- it needs to be converted to a regular node-set using the extension function xxx:node-set(), which is provided by the vast majority of XSLT 1.0 processor vendors. In this example exslt:node-set() is used, because EXSLT is implemented by many different vendors.

4. The second transformation is applied on the result of the first: . A separate mode is used in order to cleanly separate the code of the two transformations.

5. The first transformation multiplies each num/text() by 2. The second transformation increments each num/text(). The result is 2*.+1

II. This XSLT 2.0 transformation:

when applied on the same XML document, produces the same wanted and correct result.

Do note: In XSLT 2.0/XPath 2.0 the RTF type has been abolished. No xxx:node-set() extension function is needed.
