Hello all,
I want to use XML to store some data in an app I'm writing. I've always used Access and DB programming prior to this but want to learn XML. Have a very limited knowledge of XML and would like to do some basic DB stuff like;
1) Read data in.
2) Modify it.
3) Write it back out (as needed)
Any help would be appreciated.
I've googled and have found a lot but unable to find anything simple and straight forward.
Thanks,
Mike

If you want to learn about XML and related technologies, I suggest visiting this site W3 Schools[^]
To work with XML in .NET you have to deal with the classes in the System.Xml namespace. Take a look at their documentation and the continuative links that contain many useful explainations. You can start with the XmlDocument, XmlReader and XmlWriter classes.

Does anyone know how I can serialize a StringDictonary to XML? Failing that, is there another structure that I can use that is serializable? I'm trying to use WSRF.Net but my code gets halted as the structures are I use are not serializable.
I want to do so without having to use long complicated code and multi-dimensional string arrays.
My thanks in advance.

The StringDictionary has the SerializableAttribute, so you should be able to use the XmlSerializer in order to serialze or deserialize instances of the class to or from a XML document, respectively.

I know that, but this is where it gets frustrating.
StringDictionary implements the IDictonary interface and the serializer aborts saying classes implementing that interface are not supported yet.

So I guess you have to do it on your own. Should not be to hard using the XmlTextWriter and XmlTextReader classes. Simply iterate over the dictionary and use the appropriate WriteXX or ReadXX methods to store or retrieve each dictionary entry. The resulting XML could look like that:
<dictionary>
<entry>
<key>key1</key>
<value>value1</value>
</entry>
<entry>
<key>key2</key>
<value>value2</value>
</entry>
...
</dictionary>

It would be very helpful to see the code you're talking about.

Hello.
I need to insert MS Word and MS Excell documents directly into html file. I use <object> tag for these perposes. Everything is ok and the whole documents can be viewed in IE through html file. But the problem is that these documents can not be printed currently from html file!
One possible reason is that version of server(office) to print these OLE objects must be exatly the same as the version of office they were created in.
Is there are any others ways to create printable html (or xml) document with office OLE objects inside?

Hi,
I thought I would try using ReadXml and WriteXml with DataTable instead of DataSet...
It appears that I need to use "XmlWriteMode.WriteSchema" when saving a DataTable if I want to read the same xml file back into a DataTable?
dt1.WriteXml("settings.xml", XmlWriteMode.WriteSchema);
dt2.ReadXml("settings.xml");
If I don't I get this error message:
"DataTable does not support schema inference from Xml"
Any enlightenment would be appreciated
thanks,
Ron

i want to change MSXML2 in MSXML6.
Dim xmlDoc As New MSXML2.DOMDocument6.0
Dim objNodeList As MSXML2.IXMLDOMNodeList6.0
Dim objNode As MSXML2.IXMLDOMNode6.0
the error: the type MSXML2.IXMLDOMNode is not defined.
i must use MSXML6.
thanks

Looks like a simple mistake in a definition.
It should look this way:
Dim xmlDoc As New Msxml2.DOMDocument30
Dim currNode As IXMLDOMNode Look at the 2nd code snippet at: http://msdn2.microsoft.com/en-us/library/ms765513.aspx

Don't worry, be happy  )

We have an xml viz.
<element>
<component>....
<event>....
<event>....
<event>....
<event>....
The number of events will be dynamic.
For a relevant component,we need to return the cooresponding events pipe-delimited.
We arrive at the particular component through SelectNodes - is there a smart,concise XPATH expression which can allow me to return the set of events in the way we want,rather than recursing through the set.
Note that component and event nodes are parent(ed) by 'element'.
We are using javascript.
