I'm having trouble saving xml files after making changes to them. I've spent all day today trying to figure this out and I've gotten nowhere.I have this xml doc:\[code\]<?xml version=1.0" encoding="utf-8"?><content> <weapon id="1234" name="blahblah"> <note info="blah blah" /> </weapon> <weapon id="5678" name="blahblah2"> <note info="blah blah" /> </weapon></content>\[/code\]This is what I've come up with so far that doesn't exactly work (Edited to show how I read file):\[code\]FileOpenPicker openPicker = new FileOpenPicker();openPicker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.DocumentsLibrary;openPicker.FileTypeFilter.Add(".xml");StorageFile gfile = await openPicker.PickSingleFileAsync()fileContent = await FileIO.ReadTextAsync(gfile, Windows.Storage.Streams.UnicodeEncoding.Utf8);Xdocument xml = XDocument.Parse(fileContent);xml.Descendants("weapon").Where(c => c.Attribute("id").Value.Equals("5678")).FirstorDefault().Remove();IRandomAccessStream writeStream = await gfile.OpenAsync(FileAccessMode.ReadWrite);Stream stream = writeStream.AsStreamForWrite();xml.Save(stream);\[/code\]The resulting xml doc would be something like this:\[code\]<?xml version=1.0" encoding="utf-8"?><content> <weapon id="1234" name="blahblah"> <note info="blah blah" /></content>apon> <weapon id="5678" name="blahblah2"> <note info="blah blah" /> </weapon></content>\[/code\]If I try to use FileAccessMode.ReadWriteNoCopyOnWrite for OpenAsync the file ends up being 0 bytes.Anybody know how I can write this file correctly while still using XDocument.Save?
