Hi,

I tried the SelectNodes and SelectSingleNode method. However, it starts its search from the root document. However, I want it to search only in its own node context. Am I missing something here?

Thanks,

Direct shove of data from an XML file to a web service.

I have a .net web service which expects a soap requested outlined by a structure of classes. Working on the client side I have created an xml file that contains everything that will be in the body of the soap envelope. If possible I want to take the contents of the xml file and shove them directly into the class and send it the web service. Here is the code I have been trying.

<br />
Dim sXMLFile As String = txtXML.Text<br />
Dim doc As New XmlDocument()<br />
Dim rc As localhost.Request<br />
<br />
Dim ds As New DataSet()<br />
Dim tbl As DataTable<br />
Dim col As DataColumn<br />
Dim row As DataRow<br />
<br />
doc.Load(sXMLFile)<br />
ds.ReadXml(New XmlNodeReader(doc))<br />
<br />
''// This doesn't work...<br />
'rc.SetInfo = ds.Tables(0).DataSet<br />
'rc.SetInfo2 = ds.Tables(1).DataSet<br />
<br />
''// This is really what I'm trying to get... <br />
''// A direct shove of the data from the XML file to thw web service.<br />
'wr.SubmitRequest(ctype(ds, localhost.Request)<br />
'wr.SubmitRequest(ctype(sXMLFile, localhost.Request)<br />
wr.SubmitRequest(ctype(XmlNodeReader(doc), localhost.Request)<br />

Is this possible and if so how?
Thanks,

Jason W.

Yep, its possible. Do you have the WSDL for the method in question? You will need to use the correct schema.

If you have the WSDL however, it would probalby be a better idea to generate a proxy and use that, much more maintainable.

Actually, I finally figured out how to do it this morning. Here is what I came up with:

Dim sXMLFile As String = txtXML.Text<br />
    Dim serializer As New XmlSerializer(GetType(localhost.RequestChange))<br />
    Dim fs As New FileStream(sXMLFile, FileMode.Open)<br />
    Dim rc As localhost.RequestChange<br />
    rc = CType(serializer.Deserialize(fs), localhost.RequestChange)

Thanks for the response,

xml formatted data from a socket to a dataset

I need to accept XML formatted data over a socket connection and place the data into a dataset for parsing. The XML data is bracketed by a start character and an end character, but may range from 50 bytes to thousands of bytes. The app will need to be in c++. ANy ideas

Thanks

Just grab the XML and use DataSet.ReadXml to load it into a DataSet object. You can use the socket stream as the parameter, or use any TextReader (such as the XmlTextReader) as the parameter. Just see the ReadXml for the overloads.

How to display xml transformed in HTML in a windows Application?

Re: Transformed XML Display

using XSL ...

Your question is way too general, so I'll recommend that perhaps you get yourself a good XML book (i.e., Teach yourself XML in 24 hours).

As for displaying HTML in a windows Application, you'll need to make use of the IBrowser/IBrowser2 interface.

One way to do this is to learn Xsl Transformations (W3C Tutorial[^]), transform Xml to Html using System.Xml.Xsl.XslTransform object and display it using WebBrowser COM object. (See Hosting a webpage inside a Windows Form[^] and Using the WebBrowser control in .NET[^])

Error while creating Xml from dataset

Hi ,
I am creating xml document from dataset.
one of my data field is of data type datetime.
so when I am converting it to xml it is getting conveted in to long date value ,but i don't want long date.
for example
my datetime field value is 8/29/2002
and it is getting converted into '2002-08-29T00:00:00.0000000+05:30'
I hope I have explained my problem to some extent.
can anybody help me out to solve this problem?
thanks

I ran into this same "issue", and I ended up just storing the Date as a string in the XML and then converting it back into a Date/Time when I read the data back in ...

There's probably a more "direct" approach to take, but this works just fine.

XML Namespace confusion

Hi...

I have createds a XML document (chart.xml) along with a seperate XML Schema (chart.xsd) document to describe the structure of the XML document and its data types.

My confusion comes in (after trying the w3CSchools explanation unsuccessfully) when namespaces need to be applied.

All I want to do is get the XML document to reference this XSD document (which are located in the same folder) so that value and elements within the XML document are of the correct format (this is what schema is for is it not?).

Also how can I tell its working properly?
Any help/pointers would be very appreicated.

John

Namespaces are used to qualify elements and attributes. They aren't necessary, but are usually a good idea so that you can easily qualify elements and attributes when using XML documents with mixed content. To use them, add the xs:targetNamespace (where xs is the namespace prefix for XMLSchemas) and then use the same namespace to qualify your XML document that you gave first. To use it as the default namespace, use xmlns="....." with no prefix.

When you're using code to access the DOM, you can use any prefix you want, so long as the namespace in the namespace manager (in .NET, this is the XmlNamespaceManager) matches (case-sensitively) the namespace declared in the document.

MSXML PARSER 4.0 problem

- IXMLDOMDocument2Ptr ObjXMLDoc;
- hresult = ObjXMLDoc.CreateInstance("Msxml2.DOMDocument.4.0");

i then perform the following call:
- ObjXMLDoc->load(Filename);

where Filename is a valid XML file (no scheme is used).
this call takes out memory resources, and when i use the same last call with a different Filename, it takes more of it - without releasing the last one's resources.

is there a way to "Unload" an xml file from memory (to perform something like the opposite of "load" method)?
