Hi All,

What is the best way to remove a collection of nodes? For example the
following XML:

<topic>
<title>Foo</title>
<title>Bar</title>
<description>Foo bar</description>
</topic>

At the moment if I want to remove all the title nodes I do the following
XPath //topic/title and loop through the XmlNodeList to remove the node one
by one.

Is there a better/quicker way to do this?

Regards,

Victor

I don't think so. What's wrong with your approach?

Nothing, I thought if there is a quicker way to do it rather than doing the
XPath it'll be better :)

Thanks,

Victor

And what's wrong with doing XPath? You can actually traverse DOM using
native DOM methods looking for nodes to remove, but that's gonna be not
so trivial and even probably slower.
