Hello,

I have one element named LoadConfig. It has one attribute named 'Type'. The attribute 'Type' can have two values('PreDefined' or 'UserDefined'). If attribute value is 'PreDefined', LoadConfig element can have 3 child elements. If attribute value is 'UserDefined' LoadConfig element can have any type xml nodes as its childnodes. Can anybody explain how to make schema for this.

Thanks,
Chito

I think you would be better off having two elements (LoadConfigDef, LoadConfigUser) with the parent having a selection of which one.

I don't know XML and I mean it. :p

I need code in VC++ that can make an XML file out of a byte array.
Can somebody help with that? Smile | :)

With out some description of your goals and what the structure of the data is in the array, any suggestions would be rather open. Have you looked through any tutorials? Like the ones I mention below.

Well do you just need to read in a string and then save it as a CData section to a single element? I would expect you wanted to organize the data in some hierarchical scheme.

Have you just browsed the XML code here in CP and looked for examples?

Kristen Wegner's is good work (along with many others) http://www.codeproject.com/soap/pugxml.asp[^]

There are several "SET" methods to add elements, attributes and their values.

Hi,

I have a xml file (e.g. mydata.xml). How am I able to make use of javascript to select elements to be displayed on a HTML?

E.g. Using dropdown menu, I select 'Name'. Onclick the Submit button will enable the javascript to pull out all the 'Name' elements in mydata.xml and display on IE. Is this possible?
Also, possible to have logical 'AND' function?

Thanks in advance. Dead | X|

XmlDocument doccy = new Document();<br />
doccy.Load(filename);<br />
<br />
XmlElement root = doccy.SelectSingleNode("rootnode");<br />
<br />
XmlElement newRecord = doccy.CreateElement("record");<br />
root.AppendChild(newRecord);<br />
<br />
doccy.Save(filename);

obviously you will need to implement a locking mechanism.

msxml 2.0 in IE

mindows24-Mar-03 5:15

24-Mar-03 5:15

I read that IE still uses msxml 2.0 for xml processing. Is this correct?

If I want to include xml functionalities in my vc++ app, is it recommended to use msxml4.0 sdk? I hate to redistribute msxml4.0 with my app. assuming that most people have IE 5+, couldn't I just use msxml2.0? (i can't seem to find much information on msxml sdk prior to version 3)
thanks in advance,

Version 3.0 of MSXML is shipped with IE5+, IE use what you tell it to use, while default is MSXML3 (not 4), for example if you create an instance of MSXML in the script with string "MSXML2.DOMDocument", version 3 will be used (assuming it is installed), but if you use "MSXML2.DOMDocument.4", you'll get a version 4.

Server side

23-Mar-03 22:28

The code I meant was your code which is giving the problem on Netscape. If you can post that code then maybe we can help you out.

From what I can gather though I recommend you ditch the client side processing and do it all server side. It is perfectly possible to apply an XSL transform to a dynamic XML source.

The best way is to have an ASPX (or ASP page) which creates an XmlDocument and XslTransform. you then load up the XmlDocument with your dynamic XML (in .NET it can take in streams or physical files) and Response.Write out the XslTransform output.

I did it for IE..ad it is working fine..but the same program doesnt give any output in netscape..that is because netscape doesnt support some of the methods..so there is no other way..than to write a new approach which either can work fine in both..IE and netscape..or write routines for netscape and IE...but I dont know the idea as how to start with...can you help me out..

you have to do this using server-side code.
client side code is not a good idea as you will face the problems that you have now.

you need to write this in code that executes on the webserver, so either asp or asp.net depending on which one you know.

Problem while using MSXML to get HTTP response

Hi,
I am using MSXML to get the response from a web server. It's really strange that everytime before I can load that page successfully, I should load that url first in my IE. Only after that, the page can be loaded in my program.
Can someone kindly tell me what the problem could be?
Thanks and nice day!

<br />
BOOL CAPIDlg::MakeRequest() {<br />
	try{<br />
		//Use MSXML::IXMLHttpRequest to send the HTTP request to the gateway<br />
		MSXML::IXMLHttpRequestPtr pIXMLHTTPRequest;<br />
		//Result of the connection<br />
		HRESULT hResult=CoInitialize(NULL);;<br />
		hResult = pIXMLHTTPRequest.CreateInstance("Microsoft.XMLHTTP");<br />
		//Open the connection<br />
		pIXMLHTTPRequest->open("POST",(_bstr_t)"http://www.yahoo.com");<br />
		//Send the request to setup the HTTP connection<br />
		pIXMLHTTPRequest->send();<br />

Hi, I find out the mistake Smile | :)

The method is
pIXMLHTTPRequest->open("POST",(_bstr_t)"http://www.yahoo.com");

shoud be "GET" instead of "POST".

strong type in XML

how to do the following using .NET

I have the following XML document :

<a>3.14159</a>

If I were using COM MSXML parser, I could get
NodeTypedValue property to get "strongly-typed"
value.

b= XMLDocument.SelectSingleNode("//b");
variant value = b.NodeTypedValue;
//now the variant contains double value.

The question is:
how to achieve the same using C# ?
Value property of XMLNode object returns String
type, wchich i have to convert to get desired type...
How to do this without explicit conversion (by the means
of XMLConvert class or similar...)

Thanks

This work ok . I had one more question . Now How can i diagramatically represent this heirarchical data ? Like everything is in One level I need some indentation !

Like
CRange
CKeyboard
COven
CDigitalInput
CDigitalOutput
CSettings

this would be really cool . This seems easy when programming in C/C++ , but how do i make XSL do this ?

Dinner time so I have to go.

Look up the parameter passing to templates. One option would be to just send a text string of blanks that is increased with each call and put that text out prior to the name you have.

www.w3schools should have a sample
