I have an existing XML stored in the InternalFielStorage as..
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root>
<Books>
<Author name="Sam" />
</Books>
</Root>
I am trying to append a "title" node under the "Author" node but the when saved, I am seeing a completly new xml added to the existing xml as..
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root>
<Books>
<Author name="Sam" />
</Books>
</Root>
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root>
<Books>
<Author name="Sam" />
<Title>Test</Title>
</Books>
</Root>
Code I am using for this..
using (IsolatedStorageFile myStore = IsolatedStorageFile.GetUserStoreForApplication()) { using (IsolatedStorageFileStream myStream = new IsolatedStorageFileStream(App.FileName, FileMode.Open, FileAccess.ReadWrite, myStore)) { XDocument _xDoc = XDocument.Load(myStream); XElement srcTree = new XElement("Title", "test"); _xDoc.Element("Root").Element("Books").Add(new XElement(srcTree)); _xDoc.Save(myStream);
QUESTIONS:
1. How can I avoid the new XML from being appended to the existing one?
2. How can I make the "title" tag to be under the <"Author name="Sam"> tag?
Thanks in advance.
When you load the stream, the position is set to the last byte of the file - you need to reset the position before saving the file.
