HELP! New to XML - simple solution needed

[Lindy]

I'm using VB .Net and am brand new to XML.
I need to create an XML file with the following lines:

<?xml version="1.0" encoding="UTF-8" ?>
- <HC_DATA xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://.../asc.xsd">

other stuff...
</HC_DATA>

I am trying to use XMLTextWriter and have access to the schema file asc.xsd
which I can add to my project.
Can anyone help me with the syntax in VB .Net in order to create these lines
using xmlns:xsi & xsi:noNamespaceSchemaLocation?

Please help - I've been researching this issue online for 2 weeks!!!
Thanks,
Lindy

Can you just write it out with something like this?
Dim writer as xmltextwriter
writer = new xmltextwriter(somefilename, nothing)
writer.formatting=formatting.indented
writer.WriteStartDocument()
writer.WriteStartElement(someelementname)
writer.WriteString(someelementstring)
writer.WriteEndElement()
......

writer.WriteEndDocument()
writer.flush()
writer.close()

Thanks Mike for your reply.
I had tried to do what you suggested and I wasn't getting the xmlns:xsi and
xsi:noNameSpaceSchemaLocation.

However, I got a reply on another post (in C# which I translated to VB).
This new code seems to work:

Dim tw As XmlTextWriter

FileName = "SmallTest.xml"
tw = New XmlTextWriter(FileName, New System.Text.UTF8Encoding)
tw.WriteStartDocument()
tw.WriteStartElement("HC_DATA")
tw.WriteAttributeString("xmlns", "xsi", _
"http://www.w3.org/2000/xmlns/", _
"http://www.w3.org/2001/XMLSchema-instance")
tw.WriteAttributeString("xsi", "noNamespaceSchemaLocation", _
"http://www.w3.org/2001/XMLSchema-instance", "http://example.com/asx.xsd")

tw.WriteEndDocument()
tw.Close()

Thanks for your reply

Did you look at
tw.WriteProcessingInstruction("xmlns:xsi","http://www.w3.org/2001/XMLSchema-
instance") ?
There are probably several ways to do it.

Thanks Mike. That looks like a good suggestion also.
I have another question that perhaps you can help me with:

I have a schema file called asc.xsd which I can add to my project.
Is there a way to access the elements, etc. from this schema in order to
simplify my writing of the elements to the new XML file?
If so, how would I do this?
I added the file to my project.
When I look at the file in the Schema layout, the top node is called
"HC_DATA". There are 3 elements in that box: HEADER, RECORDS, TRAILER. Of
course, for each of these elements, there are more details.
Is there a way to declare an object such as HC_DATA so that I can reference
each of the elements and assign values to them and write them using
XMLTextWriter?
Thanks

Well you certainly can create a class called hc_data, and be able to pass
hc_data items between functions and process more easily including writing to
an xml file. I am not sure if that is what you are getting at.

Public Class hc_data
Public hc_header as string
Public hc_records as string

etc

Public Sub New(header as string)
MyBase.New
me.hc_header = header
me.hc_records = "empty"
End Sub

Public Property records As String
Get
records = hc_records
End Get
Set
hc_records = value
End Set
End Property

etc.
End Class

Then you can use dim myhc as new hc_data("abc")
myhcdata.records = "efg"
etc.
then pass myhc on to your xmlwritefunction.

Hi Mike,
Thanks for your suggestion.
I was hoping to use the actual Asc.xsd file/class that I have added to my
project. It already has all the schema that I need.
My question is, how can I access this layout directly without having to
define each element manually.
Thanks,
Lindy
