I use this function to remove all empty elements in my xml file:
XmlNodeList emptyElements = doc.SelectNodes(@"//*[not(node())]");
for (int j = emptyElements.Count - 1; j >= 0; j--)
{
    emptyElements[j].ParentNode.RemoveChild(emptyElements[j]);
}

How can I change the script to only remove empty elements with the name category?
<category name="test" />

Try:

XmlNodeList emptyElements = doc.SelectNodes(@"//*[not(node()) and @name='test']");

Open in new window

Hi.
Thank you for your reply.
But it´s <category i want to remove.
There is serveal different names:
<category name="test1" />
<category name="test2" />
<category name="test2" />

So something like
XmlNodeList emptyElements = doc.SelectNodes(@"//*[not(node()) and NODENAME='category']");

Oh. Sorry, I misread this:

as "name attribute." My apologies. Instead of the *, why not use "category"?

e.g.

XmlNodeList emptyElements = doc.SelectNodes(@"//category[not(node())]");

Open in new window
