XSLT and function document()

[Giovanni Leonetti]

Hi folks,

I have a question about the xslt function document().
What I want to do is :
1) access to an external xml document
2) read some data from the external xml document
3) access to the input xml document.

Let's say we have the documents :
- input.xml : input document
- style.xslt : XSLT file
- external.xml : external xml document

I will run the command line :

java org.apache.xalan.xslt.Process -IN input.xml -XSL style.xslt -OUT
out.xml

about 1) and 2) I know how to access to external.xml using the
function document('external.xml')
About 3) I need your help guys . I want to access to the input.xml
document but I do NOT want to call the function
document('input.xml'). Do you know if exists a parameter for the
function document() that let me know to access to the input document
avoiding an explicit call document('input.xml') ?
I hope is is enough clear my question.
Thanks,

Giovanni Leonetti

You do not need the document function to access input.xml as it is the
primary source document so you can access it with your XPath expressions
e.g.
<xsl:variable name="main-root" select="/"/>
Then you can always use that variable $main-root if your context node is
part of a different document (e.g. external.xml).

Thanks Martin.
Now I can switch to the primary source document easily.
