Im using the code below to delete all values in a particular Genre:

XmlDocument doc = new XmlDocument();

doc.Load(iePath + "\\RadioBarPresets.xml");

foreach (XmlNode node in doc.DocumentElement.ChildNodes)

{

if (node.Name == "Genre_Genre_" + genre)

{

node.RemoveAll();

}

}

doc.Save(iePath + \\RadioBarPresets.xml);

It removes all values...but leaves the entries below in the xml file:

If I remove the Genre "Dance"....(for every element removed, left behind is-)

<Genre_Genre_Dance />
<Genre_Genre_Dance />
<Genre_Genre_Dance />
<Genre_Genre_Dance />
<Genre_Genre_Dance />
<Genre_Genre_Dance />

Still can't figure where "node" is...

Is your for loop supposed to be nested within the foreach (only place "node" is)...

cablehead,
try this:

XmlDocument doc = new XmlDocument ();
doc.Load (Path.Combine (iepath, "RadioBarPresets.xml"));
XmlNodeList list = doc.GetElementsByTagName (string.Format ("Genre_Genre_{0}", genre));
XmlNode root = doc.SelectSingleNode ("/RadioBar");
for (int i = list.Count - 1; i >= 0; i--) {
root.RemoveChild (list [ i ]);
}

OMG!

for( Int32 i = doc.DocumentElement.ChildNodes.Count - 1; i >= 0; i-- )
{
XmlNode n = node.ChildNodes[ i ];
if( n.Name == "RemoveMe" ) doc.DocumentElement.ChildNodes.Remove(n);
}

Good Coding!

Great!

for( Int32 i = doc.DocumentElement.ChildNodes.Count - 1; i >= 0; i-- )
{
XmlNode n = doc.DocumentElement.ChildNodes[ i ];
if( n.Name == "RemoveMe" ) doc.DocumentElement.ChildNodes.Remove( n );
}

Please, dont ask me about 'doc' variable ;)

Good Coding!

Hi cablehead,

You should use this snippet code:

for( Int32 i = node.ChildNodes.Count - 1; i >= 0; i-- )
{
XmlNode n = node.ChildNodes[ i ];
if( n.Name == "RemoveMe" ) node.ChildNodes.Remove(n);
}

Good Coding!

Where is node coming from in your code

XmlNode XmlNodeList

if( n.Name == "RemoveMe" ) node.ChildNodes.Remove(n);
----no definition for Remove....
