How do I extract a hexBinary attribute value?

Jambolo16-Jun-03 13:50

Jambolo

16-Jun-03 13:50

I wrote a function that gets a attribute value that is in hex. Am I reinventing the wheel? The problem is that I can't get it to work.

Here was my first attempt which failed because it didn't convert to hex (even though the the type is xsd:hexBinary):

HRESULT     hr;
CComVariant value;

hr = pElement->getAttribute( CComBSTR( sName ), &value );
hr = value.ChangeType( VT_UINT );

Here is my second attempt which works for values using digits '0'-'9' but fails for values using digits 'a'-'f' (and 'A'-'F') (VarParseNumFromStr returns DISP_E_TYPEMISMATCH):

HRESULT     hr;
CComVariant value;
NUMPARSE        np  = { 10, NUMPRS_HEX_OCT|NUMPRS_USE_ALL, 0, 0, 4 };
unsigned char   digits[10];
CComVariant vHex;

hr = pElement->getAttribute( CComBSTR( sName ), &value );

hr = VarParseNumFromStr( value.bstrVal, GetUserDefaultLCID(),
             NUMPRS_HEX_OCT|NUMPRS_USE_ALL,
             &np, digits );
np.nBaseShift = 4;
hr = VarNumFromParseNum( &np, digits, VTBIT_UI4, &vHex );
hr = vHex.ChangeType( VT_UINT );

Anyone know what is wrong or what the right way to do this is?

Hi,

I've got a strange problem. I have a multithreading Win32 MFC application used MSXML. All XML-related procedures (loading, parsing and etc) are worked in a separated thread started with _begingthread().

This thread looks like as shown below. When this thread calls IXMLDOMDocument::load() to load an existed XML document from a file, this will stop an opening all Microsoft Office 2000 documents (Word,Excel and etc).

This problem appears only under Windows 9x/ME.

What's wrong? Help me!

void XMLTrafReportThreadFunction(void *)
{
::CoInitializeEx(NULL,COINIT_MULTITHREADED);

IXMLDOMDocumentPtr XmlDocPtr;
_bstr_t bstrXMLReport(lpszFilename);
VARIANT_BOOL vtResult;

HRESULT hr = XmlDocPtr.CreateInstance(MSXML::CLSID_DOMDocument);
if (FAILED(hr)) return 0;

vtResult=XmlDocPtr->load(bstrXMLReport);
...
...
}

Yours sincerely,

Hi,

I have created a simple MFC/C++ Program that uses MS XML 3.0 and Below is the code as well as XML file. Its a very smal XML file and I need to parse it and get info like

Can anyone point out where I am going wrong ??? XMLPad.exe parses it properly !! Help..

XML file is:

<CAPABILITY VALUE = "0x051" />
<CHAN NUMBER = "10" />
<CHAN STRENGTH = "2" />

Attributes aren't part of the child tree as you are trying to use it. Attributes are considered separate by the DOM and need to be accessed via IXMLDOMElement::getAttribute or IXMLDOMNode::attributes, with the later being best for you usage as you can iterate over all available attributes.

Hello,

I have created XSD file using Visual Studio .NET and
was trying to load it using your "XML Data Editor".

It does not react at all. The XSD file is very simple.

What I did : I took yours sale5.xml into VS.NET and created
schema. Then was trying to load it into your Data Editor.

Please advise.

Thank you in advance.

Hi everyone,

I'm new to XML and my question is how does one use the Expat library to look for let’s say all of the authors in a XML file.

Any help would be greatly appreciated.
Ken

Re: Expat XML

Expat uses a callback mechanism to parse documents (similar to SAX). So, basically you make a callback function for elements that checks if the element is an "author" (and does something with that data), you register that handler, then you start the parser.

There is a good tutorial on getting started with Expat here:
"Using Expat" by Clark Cooper.

Just looking for some recommendations here -- I am gonna implement some XML for a network protocol, maybe using SOAP.

Any recommendations for a fast XML parser? Doesn't need to be fancy.... but does need to be more than a token parser....

Thanks in advance!

Serializing XML element with scope in .NET

Chris Maunder24-May-03 18:46

Chris Maunder

24-May-03 18:46

I have a class that contains elements:

class MyClass {
int var1;
string var2;
}

I'm using the XmlSerializer class to output objects of MyClass to an XML stream and I'm trying to work out how to get the output to be like:

...
<var1>Value 1</var1>
<prefix:var2>Value 2</var2>
...

I've played around with the XmlElementX attributes classes but no luck. The XmlElement.Prefix property seems to be one solution, except that the compiler barfs saying Prefix isn't a member (contradicting the docs and intellisese).

Any ideas?

cheers,
Chris Maunder

Could anyone explain to me how to get the XML file from the Seti@Home stats webservice into a dataset. I keep getting errors that I can't remember exactly, but something along the lines of it can't be placed in a single table relationship.

So is it the way the xml file received from the webservice not workable with a dataset? Is there anyway I can make parts of it go into seperate tables?

Any insight on this would be very helpful.

How do I move XML nodes?

lnong15-May-03 10:16

lnong

15-May-03 10:16

I am working on an ASP.NET application using C#.

In my XMLDocument, I have a node (that contains other nodes within) that I want to move to another location in the tree. How do move that node AND everything it contains?

Is there a MoveNode() method? All I see is a ReplaceChild() method. Will that do the job? The only way I could think of using the ReplaceChild() method is the create a new XMLNode at the new desired location, and then replacing that node with the old one. Then use RemoveChild() to delete the old node. Any better ways? Thanks.

Try something like:

XmlNode MoveNode(XmlNode nodeToMove, XmlNode newParent)
{
    // Check we have some values:
    if (null == nodeToMove) throw new ArgumentNullException("nodeToMove");
    if (null == newParent) throw new ArgumentNullException("newParent");
    
    // Are we moving within the same document?
    if (nodeToMove.OwnerDocument == newParent.OwnerDocument)
    {
        // Check that the new parent is not a
        // child of the node we are moving:
        XmlNode temp = newParent;
        while(null != temp)
        {
            if (temp == nodeToMove) 
                throw new InvalidOperationException();
            
            temp = temp.ParentNode;
        }
        
        // Remove the node from its old parent:
        if (null != nodeToMove.ParentNode)
            nodeToMove.ParentNode.RemoveChild(nodeToMove);
        
        // Add the node to the new parent:
        return newParent.AppendChild(nodeToMove);
    }
    else
    {
        // Import the node to the new document
        XmlNode newNode = newParent.OwnerDocument.ImportNode(nodeToMove, true);
        
        // Remove the node from its old parent:
        if (null != nodeToMove.ParentNode)
            nodeToMove.ParentNode.RemoveChild(nodeToMove);
        
        // Add the imported node to the new parent:
        return newParent.AppendChild(newNode);

How to update a XML file

Hi all,

I have very newbie question concerning VB.NET and XML.

I have an Xml file like this (simplified):

<personnel>
<person>
<person_id>123</person_id>
<name>John Doe</name>
</person>
...
<person>
<person_id>890</person_id>
<name>Mary Somebody</name>
</person>
</personnel>

I can extract info from it but I don't know how to update it? Eg. Mary Somebody gets married and her name will be Mary Doe.

I will be most grateful any advice or links to info.

TIA
