Get new xml from PDF viewer based on schema/class

Hi,

We use Adobe LCA in our project. we implement with Microsoft .NET C# language in our project.

My question is: i want to get the xml from the pdf document.

steps i perform is.

1)Get the current xml from Database.

2)Load the current xml into pdf form, by calling LCA webservice. Once the form is loaded, xml is updated/changed.

3)Get the new xml from Pdf.

We used webcontrol in c# to load the pdf.

how to convert the pdf to xml , we have the schema/class for it.

Could you please give the code in c#.

i believe we need to use some memory stream/ input stream/ byte array conversion.
