Load XML file

[shapper]

Hello,

I am opening a xml document as follows:

XDocument _categories = XDocument.Load(String.Concat(path,
"Categories.xml"), LoadOptions.SetBaseUri);

Then I am adding a few Category nodes and saving it as follows:

_mimes.Save(new Uri(_categories.BaseUri).LocalPath);

If "Categories.xml" is not found when loading how can I create a new
one with this content:

<?xml version="1.0" encoding="utf-8" ?>
<Categories/>

Then I will add the Category nodes as usual and save it at the end as
Categories.xml on the defined path.

Thanks,
Miguel

Hi Peter,

I was using File.Exists or the other option was using a Try Catch
Block.
If it does not exist than I would create the XDocument.

Anyway, I was able to solve it this way.

Thanks,

You should only use try/catch. File.Exists() is a waste of time,
because you always _have_ to have the try/catch block anyway. Even if
File.Exists() returns true, the file could disappear before you can
actually open it and load it as an XDocument, and you could experience
other errors as well.
