updating an XML file in VB

[RustyFuture]

Hi Guys,

I have a friend who is developing a dvd store in Visual basic ( It's a
WPF application) and stores the data in an XML file.

the content of the XML look like this:

<DVDInfo>
<DVD>
<DVDTitle>The Exorcist</DVDTitle>
<Director>William Friedkin</Director>
<Cast>Linda Blair</Cast>
<Description>Horror</Description>
<Rating>18</Rating>
<Cost>7.99</Cost>
<Copies>0</Copies>
<Rental>0</Rental>
<Image>Exorcist.jpeg</Image>
</DVD>
<DVD>
<DVDTitle>The Matrix</DVDTitle>
<Director>Wachowski</Director>
<Cast>Keanu Reaves</Cast>
<Description>Action</Description>
<Rating>15</Rating>
<Cost>7.99</Cost>
<Copies>20</Copies>
<Rental>0</Rental>
<Image>Matrix.jpeg</Image>
</DVD>
<DVD>
<DVDTitle>The Sahara</DVDTitle>
<Director>Breck Eisner</Director>
<Cast>Matthew McConaughey</Cast>
<Description>Action</Description>
<Rating>12</Rating>
<Cost>8.99</Cost>
<Copies>20</Copies>
<Rental>0</Rental>
<Image>sahara.jpeg</Image>
</DVD>
<DVD>
<DVDTitle>Constantine</DVDTitle>
<Director>Francis Lawrence</Director>
<Cast>Keanu Reaves</Cast>
<Description>Horror</Description>
<Rating>15</Rating>
<Cost>5.99</Cost>
<Copies>20</Copies>
<Rental>0</Rental>
<Image>Constantine.jpeg</Image>
</DVD>
</DVDInfo>

He needs a way to update the file so he can add other DVD's into the
file from a form in vb

He has a Textbox input for each node from DVD title through to Image
and a button on the form.

I had thought of using the XMLreader and XMLWriter within VB but don't
know how to go about it.

Can someone help?

thanks guys,

You've got 2 easy options.

1 - Create an object oriented system where each DVD element is an
object with Title, Director, Cost etc. as properties. You can then
store these in some kind of collection and create a new one from your
form data to add to the collection. Then when you need the xml, you
can serialize your collection.

2 - Open the document as an XmlDocument and use the xml namespace to
create new elements and add them. e.g:
(Please forgice any syntax errors, I'm a C# guy and am writing from an
old memory of doing this)

Dim dvdxml As XmlDocument = XmlDocument.Open(filepath)
Dim newDvd as XmlNode
newDvd = XmlDocument.CreateElement()
etc.

Personally, I wouldn't even consider any other option other than the
first... of course fine tuning it to the requirement. ;-)

Thanks guys, I've got it working now using the XMLdocument by CK.
