Remove Element and Attributes

[Gerry Viator]

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

DOM solution - load document into XmlDocument, locate the element and
remove it.
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?

This would be fine. Thanks

Thank for Oleg's Idea. 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.

Thanks again,

What if I wanted to change the value below of TEST2?

<Width>300</Width>

to 350?

and add this to TEST2?

<Location>True</Location>

thanks for your help

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]

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.

Thanks
Gerry
