Set up XML schema

When you export to XML, you can either use the default XML schema or create a custom one.

Default XML Schema

See the description of the default XML schema in Help, chapter Specifications → Export Formats → XML Schema Description

The schema itself can be found in the Inc folder (%ProgramData%\ABBYY\SDK\12\FineReader Engine)

Modifying the Default XML Schema

You can use the following properties of the XMLExportParams object to add or remove some elements from the default XML schema:


Full information is in FineReader Engine Help, chapter "API Reference → Parameter Objects → Export Parameters → XMLExportParams".

Custom XML Schema

It is also possible to use a custom schema. You can create one by simply typing it in a text editor such as StreamWriter and saving it as an XML file.

This is illustrated by the code sample below.

The sample code does the following:

saves pictures from a recognized document separately;
writes an XML file that looks like
Visual Basic Sample Code

Imports System.IO.StreamWriter

Private Sub Export(ByVal FRDocument As FREngine.FRDocument, ByVal filePath As String)

' Declare a FileStream and create a xml document file named file with access mode of writing
Dim fs As New FileStream(filePath, FileMode.Create, FileAccess.Write)
' Create a new StreamWriter and pass the filestream object fs as argument
Dim s As New StreamWriter(fs)

' Write text to the newly created file
s.WriteLine("<?xml version='1.0' encoding='UTF-8'?>")

Dim imagesFolderName As String
imagesFolderName = …
Dim imagesPath As String

Dim Blocks As FREngine.LayoutBlocks

For PagesIndex As Integer = 0 To FRDocument.Pages.Count - 1
Blocks = FRDocument.Pages(PagesIndex).Layout.Blocks
For BlocksIndex As Integer = 0 To Blocks.Count - 1
If Blocks(BlocksIndex).Type = FREngine.BlockTypeEnum.BT_RasterPicture Then
Dim ImageModification As FREngine.ImageModification
ImageModification = Engine.CreateImageModification
imagesPath = …
s.WriteLine("<" + imagesPath + ">")
End If
Next BlocksIndex
Next PagesIndex

' Close the file
End Sub
