.NET Forum / .NET Framework / XML / October 2003Remove Element and Attributes
Hi all, The following is part of XML file, how do I search through the file and remove an Element and all it's attributes. Example: TEST2? Of course I will pass the Element Name to remove from a control. - <Forms> - <Form Name="TEST1"> <Width>600</Width> <Height>400</Height> <Tag>2-1</Tag> </Form> <Form Name="TEST2"> <Width>200</Width> <Height>26</Height> <Tag>2-3</Tag> </Form> <Form Name="TEST3"> <Width>300</Width> <Height>45</Height> <Tag>2-4</Tag> </Form> </Forms> To look like this? <Forms> - <Form Name="TEST1"> <Width>600</Width> <Height>400</Height> <Tag>2-1</Tag> </Form> <Form Name="TEST3"> <Width>300</Width> <Height>45</Height> <Tag>2-4</Tag> </Form> </Forms> Thanks Gerry > The following is part of XML file, how do I search through the file and > remove an > Element and all it's attributes.

XSLT solution - identity transfomation + custom template for Form element. XmlReader solution - read till the element, skip till EndElement and continue. Which one do you prefer?  SignatureOleg Tkachenko http://www.tkachenko.com/blog Multiconn Technologies, Israel DOM solution - load document into XmlDocument, locate the element and remove it This would be fine.

I attach some sample code as the supply to his post: Dim xmldoc As New XmlDocument xmldoc.Load("c:\edit1.xml") Dim xmlnode As XmlNode For Each xmlnode In xmldoc.DocumentElement.ChildNodes If xmlnode.Attributes("Name").Value = "TEST2" Then xmldoc.DocumentElement.RemoveChild(xmlnode) End If Next xmldoc.Save("c:\edit2.xml") Gerry, Hope this answer your question.

Gerry, to avoid asking such simple questions learn about using XmlDocument class, e.g. "Modifying Nodes, Content, and Values in an XML Document" [1] "Inserting Nodes into an XML Document" [2] "Select Nodes Using XPath Navigation" [3] [1] http://msdn.microsoft.com/library/en-us/cpguide/html/cpconmodifyingnodescontentv aluesinxmldocument.asp [2] http://msdn.microsoft.com/library/en-us/cpguide/html/cpconinsertingnodesintoxmld ocument.asp [3] http://msdn.microsoft.com/library/en-us/cpguide/html/cpconselectnodesusingxpathn avigation.asp SignatureOleg Tkachenko http://www.tkachenko.com/blog Multiconn Technologies, Israel Thanks for links, I also wish Microsoft would make there HELP much better then it is. On line and within VS.NET. I always search first, but get frustrated with not findings what I'm looking for. Microsofts Help can be made alot better. I do beleive they are going to make major changes to it from what I hear.
