Howto: Add XML Attributes to a dataset?

[Pipo]

Hi,

I fill myDataset from a Excel file.
Then I do a myDataset.WriteXML("C:\MyXML.xml")
So far everything goes as I want to.

But I need a attribute when a node has a value
e.g.:

I get:
<Node1 />
<Node2>SomeValue</Node2>
<Node1 />

What I need is:
<Node1 />
<Node2 Changed="True">SomeValue</Node2>
<Node1 />

But how can I get this?
I tried filling a dataset by reading in a XML file the way I want but I cant
find any difference.
I spend the whole day searching and trying but no luck.
Someone knows how to do this?

Many thanks!

Hi Pipo,

First of all, I would like to confirm my understanding of your issue. From
your description, I'm not quite sure what you need to do. Do you mean that
you need to write the DataSet to an Xml file with your own Changed
attribute set to true?

If so, I think we cannot do this directly with DataSet.WriteXml method,
since this is the default behavior of DataSet. If you need to add your own
attribute, I think you have to make a subclass of DataSet and implement
your own WriteXml method.

HTH.

Thanks for your reply Kevin,

Yes you're right that's was what I meant.
To bad to hear I cant provide my own attribute to the dataset.

Do you mean by I cant provide my own attribute that there are other
(standerd)
attribute(s) I can generate by the default Dataset.WriteXML method?

Thanks again

Hi Pipo,

Yes, we cannot do that with current DataSet. If we need to achieve this, we
have to implement the WriteXml method by our own.
