Scheduling an extract of metadata

The xmlExtractOptions object has properties that control what is extracted (eg XmlLoadExtractType.ApplicationDashboards). Unfortunately I haven't found any documentation and intellisense doesn't work. In short the way I do it is extract everything and then read the output zip file and pick off the Metadata.XML file like this:

' You will need these imports:
' Imports System.IO.Compression
' Imports System.Xml

Dim xmlOptions As New XmlExtractOptions
xmlOptions.ExtractAllItems = True

'Execute the Metadata Extract
Using dbConnFW As DbConnInfo = BRApi.Database.CreateFrameworkDbConnInfo(si)
	Using dbConnApp As DbConnInfo = BRApi.Database.CreateApplicationDbConnInfo(si)
		Dim zipBytes As Byte() = ApplicationZipFileHelper.Extract(dbConnFW, dbConnApp, Nothing, xmlOptions)
		' Decompress the zipped bytes into memory
		Using zipStream As New MemoryStream(zipBytes)
			Using archive As New ZipArchive(zipStream, ZipArchiveMode.Read)
				' Iterate through each entry in the zip archive
				For Each entry As ZipArchiveEntry In archive.Entries
					If entry.fullname.toupper = "METADATA.XML" Then
						' Read the contents of the entry into a string
						Using entryStream As Stream = entry.Open()
							Using reader As New StreamReader(entryStream)
								Dim contents As String = reader.ReadToEnd()
								' Save file ...
							End Using
						End Using
						Exit For
					End If
				Next
			End Using
		End Using
	End Using
End Using

If you then want a particular dimension, I would load the file into an XML document and parse out the dimension you want. Then convert it to a csv file.
