Hi,

Please help in solving the problem.

I have to merge the input xml with another external xml

Requirements are :

1. The input and external xmls are generated from the same schema
2. The external xml we get in string format through a java method call
from the xsl
3. If any extra tag is populated in the external xml, merge that tag with the input xml

Example:
say the common xml generated from schema is
<xml>
<bookstore>
<book>
<name>String</name>
<auther>String</auther>
<price>String</price>
</book>
</bookstore>
</xml>

The input xml:
<xml>
<bookstore>
<book>
<name>Java</name>
</book>
</bookstore>
</xml>

The external xml received as a string is:
<xml>
<bookstore>
<book>
<name>Java</name>
<auther>Sun micro systems</auther>
<price>100$</price>
</book>
</bookstore>
</xml>

The result should look like:
<xml>
<bookstore>
<book>
<name>Java</name>
<auther>Sun micro systems</auther>
<price>100$</price>
</book>
</bookstore>
</xml>

Note: I cant set any parameter in transformer class
I am using xalan 2.7.1 transformer

Thanks in advance
Manjunath

Hi Manjunath,
I am not sure you can do it easily; AFAIK, Xalan doesn't have an extension function that parses a string into a DOM tree (Saxon has it).
Furthermore, building an XSLT stylesheet that compares two trees and generate a merged version is something unrelated to a forum for Stylus Studio users; have you tried asking for help in a Xalan-specific mailing list?

Hi Alberto,

Thanks for your advice.

I am able to store the external xml as a nodeset in an xsl variable. able to parse through xpath.

Atleast now is it posssible to build the xsl to meet the requirements?

Please suggest,
Manjunath

Hi Manjunath,
as I told you before, this focus of this forum is Stylus Studio; we also offer our customers advice on the XSLT and XQuery languages, but we don't write algorithms for them (that would be a task for a consultant).
