Re: XML Tree in MusicBrowser

Hi,

Just a quick update if anyone is interested. The definition of the tree i=
s =20
now a preference, and can be changed at run time using the editor found a=
t =20
"View -> Custom Tree...". The XML parser is hopefully much more error =20
tolerent as well. So feel free to give it a whirl. If anyone wants some =20
help with how to define trees, I'll be happy to help.

As to my other email ("Possible new implementation of readEntries(...)") =
I =20
have now got a working implementation of this, which now provides support=
 =20
for CD listings in the tree again.

There are still things that need work, including re-adding the Edit =20
Info/Remove pop-up menu items, so I won't be adding this to CVS quite yet=
 =20
unless anyone wants me too.

As mentioned below, its avaliable from the =20
[email protected]/zinf--xmltree Arch branch.

Cheers,
David
