Editing an xml string

[ee0jmt]

Hopefully an easy question:

Using vb.net I have opened an xml file (which is encrypted) retreived the file information as a string, carry out some editing of the xml data. I now want to produce a string with the edited information so that I can pass it to a function which will encrypt and save the xml file.

I can do all of the above except for the regenerating the edited xml data into a string after it has been edited.

This is my code:

Dim xmlDoc As New XmlDocument
Dim userNodes As XmlNodeList
Dim userDetailNodes As XmlNodeList
Dim userNode As XmlNode

xmlDoc.LoadXml(xmlString)

userNodes = xmlDoc.GetElementsByTagName("User")

For Each userNode In userNodes

userDetailNodes = userNode.ChildNodes

userDetailNodes(userNameLoc).InnerText = userName

next

*********
All of the above works fine (Its only an extract to give you the basic idea)

Now I would like to pass the xml string to my function:

saveFile(xmlString)

however xmlString does not contain the updated information.

I have got around this problem by saving the xmldoc as a temp file, loading the temp file into a string and then saving it back into the encrypted file (code below) but there must be a better way of doing this???? All help appreciated!



xmlDoc.Save("C:\temp.xml")
Dim fs As New FileStream("C:\temp.xml", FileMode.Open, FileAccess.Read)
Dim sr As New StreamReader(fs)
Dim tempText As String
tempText = sr.ReadToEnd()
fs.Close()
My.Computer.FileSystem.DeleteFile("C:\temp.xml")
saveUserDetails(tempText)
