xslt transformations

[Seesharp2008]

Hi guys!

I want to do a sequence of transformations on an xml file. here is the scenario:

Input.xml-------XSLT------>output.xml------XSLT------->output.xml.... ...

for fulfiling this i have to save the first output on my hard disk and then use it again.
What I have done is to copy the out put in to a temp.xml file , delete the out put file and use the temp.xml file as the input for the second transformation.

But it fails and the output isn't what I expected.
Do u have any ideas ?
Thank u in advanced.

Why are you deleting the output file? Why not use that as input to the 2nd transformation?

It's hard to tell what's wrong just from this description. Could you post the code you're using to do the transforms?

Yes I'll copy the code.

XslCompiledTran sform xslt = new XslCompiledTran sform();
xslt.Load(xsltI nput);// there are 2 .xsl files

if (!File.Exists(@ "c:\temp.xm l"))
{
xslt.Transform( @"c:\student.xm l",@"c:\output. xml")
File.Copy(@"c:\ output.xml", @"c:\temp.xml") ;
File.Delete(@"c :\output.xml");
}
else
{
xslt.Transform( @"c:\temp.xm l", @"c:\output.xml ");
File.Delete(@"c :\temp.xml");
File.Copy(@"c:\ output.xml", @"c:\temp.xml") ;
File.Delete(@"c :\output.xml");
}


}
}

I have to delete output file because it will be created at the next step again.

Let me get this straight. 1st run through: temp.xml does not exist, we go into the first section.
2nd run through: temp.xml exists from the previous transformation, we go into the 2nd section.
You call this function twice, with different values for xsltInput.

Instead of in the first section

xslt.Transform(@"c:\student.xml",@"c:\output.xml") 
File.Copy(@"c:\output.xml", @"c:\temp.xml");
File.Delete(@"c:\output.xml");

Why not just:

xslt.Transform(@"c:\student.xml",@"c:\temp.xml") 

We already know the file doesn't exist.

2nd run through. Why are we copying the result back to temp.xml? Don't we want it in C:\output.xml now?

In the first case I agree with you, but in 2nd, If I want to do more transformations , I need to use the temp as new input and I need output.xml for the result of this transformation. ..therefore I have to delete output again.

Where does the output go though?
If you want to do more transformations , you'll have to delete temp.xml; otherwise you'll start off from the 2nd step with the wrong xml/xsl combination.
