How to migrate from XslTransform to XslCompiledTransform
- by Atara
I have the following code that I need to migrate from VS 2003 (.Net 1.1) to VS 2008 (.Net 2+)
but I get compilation error -
System.Xml.Xsl.XslTransform' is obsolete: This class has been deprecated.
I probably need to use System.Xml.Xsl.XslCompiledTransform instead.
but I do not find the matching Load() and Transform() overload versions that I can use with all the parameters of my original code.
in MSDN [How to: Migrate Your XslTransform Code] I only found some simpler cases.
http://msdn.microsoft.com/en-us/library/aa983475%28VS.80%29.aspx
but in my code I see some remarks that hints that the added parameters were used to avoid exceptions, so I prefer to use these parameters.
Can someone please help migrating this code?
Thanks,
Atara
