XMLMapping Object

  • Article
Word Developer Reference

Represents the XML mapping on a ContentControl object between custom XML and a content control. An XML mapping is a link between the text in a content control and an XML element in the custom XML data store for this document.

Remarks

Use the SetMapping method to add or change the XML mapping for a content control using an XPath string. The following example sets the built-in document property for the document author, inserts a new content control into the active document, and then sets the XML mapping for the control to the built-in document property.

Visual Basic for Applications 
  Dim objcc As ContentControl
Dim objMap As XMLMapping
Dim blnMap As Boolean

ActiveDocument.BuiltInDocumentProperties("Author").Value = "David Jaffe"


Set objcc = ActiveDocument.ContentControls.Add _
(wdContentControlDate, ActiveDocument.Paragraphs(1).Range)


Set objMap = objcc.XMLMapping
blnMap = objMap.SetMapping(XPath:="/ns1:coreProperties[1]/ns0:createdate[1]")


If blnMap = False Then
MsgBox "Unable to map the content control."
End If

Use the SetMappingByNode method to add or change the XML mapping for a content control using a CustomXMLNode object. The following example does the same thing as the previous example, but uses the SetMappingByNode method.

Visual Basic for Applications 
  Dim objcc As ContentControl
Dim objNode As CustomXMLNode
Dim objMap As XMLMapping
Dim blnMap As Boolean

ActiveDocument.BuiltInDocumentProperties("Author").Value = "David Jaffe"


Set objcc = ActiveDocument.ContentControls.Add _
(wdContentControlDate, ActiveDocument.Paragraphs(1).Range)


Set objNode = ActiveDocument.CustomXMLParts.SelectByNamespace _
("http://schemas.openxmlformats.org/package/2006/metadata/core-properties") _
(1).DocumentElement.ChildNodes(1)


Set objMap = objcc.XMLMapping
blnMap = objMap.SetMappingByNode(objNode)

The following example creates a new CustomXMLPart object, loads custom XML into it, and then creates two new content controls and maps each to a different XML element within the custom XML.

Visual Basic for Applications 
  Dim objRange As Range
Dim objCustomPart As CustomXMLPart
Dim objCustomControl As ContentControl
Dim objCustomNode As CustomXMLNode

Set objCustomPart = ActiveDocument.CustomXMLParts.Add
objCustomPart.LoadXML ("<books><book><author>Matt Hink</author>" & _
"<title>Migration Paths of the Red Breasted Robin</title>" & _
"<genre>non-fiction</genre><price>29.95</price>" & _
"<pub_date>2/1/2007</pub_date><abstract>You see them in " & _
"the spring outside your windows.  You hear their lovely " & _
"songs wafting in the warm spring air.  Now follow the path " & _
"of the red breasted robin as it migrates to warmer climes " & _
"in the fall, and then back to your back yard in the spring." & _
"</abstract></book></books>")


ActiveDocument.Range.InsertParagraphBefore
Set objRange = ActiveDocument.Paragraphs(1).Range
Set objCustomNode = objCustomPart.SelectSingleNode _
("/books/book/title")
Set objCustomControl = ActiveDocument.ContentControls _
.Add(wdContentControlText, objRange)
objCustomControl.XMLMapping.SetMappingByNode objCustomNode


objRange.InsertParagraphAfter
Set objRange = ActiveDocument.Paragraphs(2).Range
Set objCustomNode = objCustomPart.SelectSingleNode _
("/books/book/abstract")
Set objCustomControl = ActiveDocument.ContentControls _
.Add(wdContentControlText, objRange)
objCustomControl.XMLMapping.SetMappingByNode objCustomNode


MsgBox objCustomControl.XMLMapping.IsMapped

Use the Delete method to remove the XML mapping for a content control. Deleting the XML mapping for a content control deletes only the connection between the content control and the XML data. Both the content control and the XML data remain in the document. The following example deletes the XML mapping for all content controls in the active document that are currently mapped.

Visual Basic for Applications 
  Dim objCC As ContentControl

For Each objCC In ActiveDocument.ContentControls
If objCC.XMLMapping.IsMapped Then
objCC.XMLMapping.Delete
End If
Next

Use the IsMapped property to determine if a content control is mapped to an XML node in the document's data store. The following example deletes the XML mapping for all mapped content controls in the active document.

Visual Basic for Applications 
  Dim objCC As ContentControl

For Each objCC In ActiveDocument.ContentControls
If objCC.XMLMapping.IsMapped Then
objCC.XMLMapping.Delete
End If
Next

Use the CustomXMLNode property to access the XML node to which a content control maps. Use the CustomXMLPart property to access the XML part to which a content control maps. For more information about working with CustomXMLNode and CustomXMLPart objects, see the respective object topics.
