Moving data from one doc to another

Hello,

I am using Aspose.word and I seem to have a problem moving data from one doc to another.

Here is my problem.

I have Doc1.doc that contains all kind of mergefileds. I pock my values as follow:

Example:

For Each fld In doc.MailMerge.GetFieldNamesEx
builder.MoveToMergeField(fld)
builder.Font.Name = "Arial"
Select Case fld
Case "Applicant.Name"
For Each elm In XmlDoc.DocumentElement.SelectNodes("production")
builder.Write(elm1.GetAttribute(FieldName)) 
Next
End select
next 

One of MergeField need to get it’s data from other document (Formatted), so I tried to uses Section class:
Here is what I have done.

Private _subSection As Aspose.Word.Section
docsub = word.Open(MapPath(".") + "SubDoc.doc")
If (docsub.Sections.Count > 0) Then
_subSection = docsub.Sections(0)
End If

Now that I Have my section. What can I do load my Doc1 using builder.Write.
Would I be able to covert my section to string?

Try Section.Range.Text
