    }
}

Sample.java

Document filteredData = Data.transformXmlDocument(
    myXmlDocument, 
    this.getResources().openRawResource(R.raw.xsltfile)
);

I wrote this when I needed to take an XML document received from a web service and then transform it using XSLT into a format which would be easier to consume. This meant matching items with their parent entries and filtering out the bulk of the non-required data.

As it took me so long to figure it out, and seeing that there were a number of other similar requests on the web I thought I'd post it up here so that anyone else can use/modify it for their own needs.

One important note, the XSLT file must be placed into the res/raw folder, placing it in the res/xml folder will result in an error when attempting to read the data, as well as build issues if the XSLT happens to refer to "@id" attributes in the XML.

Excellent job!

Please upload Total project for Eclipse .Because i'm not able to pass an arguments to transformXmlDocument method.
along with inputs XML and XSLT files.

Thanks in Advance!

Everything good except image viewing problem. Please help. :)
