What do you mean by processing? If you are looking for endpoints for different companies to send stuff to, then you might be better looking at webservices and an asp.net application...

I'm not sure off hand what's happening in your code, but I have an example that's worked for me. strXMLDoc should be the full XML text, and urlPath should be the path to your schema, which I believe is what your example was expecting. Try this...
private System.Collections.Specialized.StringCollection errors =
new System.Collections.Specialized.StringCollection();
private System.Collections.Specialized.StringCollection warns =
new System.Collections.Specialized.StringCollection();
public bool ValidateMapData(string strXMLDoc, string urlPath) {
errors.Clear();
warns.Clear();
System.Xml.XmlTextReader tr = new System.Xml.XmlTextReader(new System.IO.StringReader(strXMLDoc));
System.Xml.XmlValidatingReader vr = new System.Xml.XmlValidatingReader(tr);
try {
vr.Schemas.Add(System.Xml.Schema.XmlSchema.Read(new System.IO.StringReader(urlPath),
new System.Xml.Schema.ValidationEventHandler(MessageHandler)));
vr.ValidationType = System.Xml.ValidationType.Schema;
} catch (Exception ex) {
while (ex != null) {
errors.Add(ex.Message);
ex = ex.InnerException;
}
}
try {
while(vr.Read());
} catch (Exception ex) {
while (ex != null) {
errors.Add(ex.Message);
ex = ex.InnerException;
}
}
string msgs = string.Empty;
foreach (string s in errors) {
msgs += "\r\nError: " + s;
}
foreach (string s in warns) {
msgs += "\r\nWarning: " + s;
}
if (errors.Count > 0) {
msgs = "Errors validating..." + msgs;
MessageBox.Show(this, msgs, "Schema validation", MessageBoxButtons.OK, MessageBoxIcon.Error);
} else if (warns.Count > 0) {
msgs = "Warnings validating..." + msgs;
MessageBox.Show(this, msgs, "Schema validation", MessageBoxButtons.OK, MessageBoxIcon.Warning);
} else {
return true;
}
return false;
}
private void MessageHandler(object sender, System.Xml.Schema.ValidationEventArgs args) {
if (args.Severity == System.Xml.Schema.XmlSeverityType.Error) {
errors.Add(args.Message);
} else {
warns.Add(args.Message);
}
}

I'm using C# in VS2005 to do some XPath queries. I've created my XPath statement using XMLSpy and it is something like:
//Unit/concat(productCode, ":", serialNumber)
I also tried with string-join, but I get the same error when I try it in my C# code:
Unhandled Exception: System.Xml.XPath.XPathException: '//Unit/concat(productCode,":",serialNumber)' has an invalid token.
Surely the concat function exists in the .net xpath library, am I doing something wrong?
The code around this is the standard routine:
<br />
xpathDoc = new XPathDocument(Filename);<br />
xpathNav = xpathDoc.CreateNavigator();<br />
xpathIter = xpathNav.Select(XPathString);<br />
- loop through the results etc -<br />
I hope someone has some pointers as to what could be wrong
Thanks

There are a few things there... You're not closing all your elements, or starting or closing the document. And for reasons I don't understand, XmlDoc.Load(stream) doesn't work, but if you use a StreamReader to read it and output that to a string, XmlDoc with LoadXml() fine. Also, before reading you have to set the stream's Position to 0. Sorry, my answer's in C#, but it should be difficult to convert to VB...
MemoryStream m = new MemoryStream();
XmlDocument XmlDoc = new XmlDocument();
System.Xml.XmlTextReader reader = new XmlTextReader(m);
XmlTextWriter textWriter = new XmlTextWriter(m, System.Text.Encoding.UTF8);
textWriter.WriteStartDocument(true);
textWriter.WriteStartElement("ns0", "HCNET_ACK_Root", "http://HoHOHo.PCNET.IB.Schema.ExternalSchema.PCNET_ACK");
textWriter.WriteStartElement("BVN");
textWriter.WriteStartElement("SendingPerson", "");
textWriter.WriteString("Terry");
textWriter.WriteEndElement();
textWriter.WriteEndElement();
textWriter.WriteEndElement();
textWriter.WriteEndDocument();
textWriter.Flush();
m.Position = 0;
System.IO.StreamReader sreader = new StreamReader(m);
string xml = sreader.ReadToEnd();
textWriter.Close();
reader.Close();
XmlDoc.LoadXml(xml);

I was wondering how to just get XSL to spit out every thing in an XML file regardless of the element its in?
At the moment, from what i have read, I use a command like so to read XML elements:
<xsl:value-of select="somthing"/>
<xsl:value-of select="somthingElse"/>
<xsl:value-of select="blah"/>
But say I had an XML file with a load of different elements and i just want the XSL to just blast them all to the page how do i tell it to write out any and every element the loop runs into?
so if i had a totaly chaotic XML file like:
<blah>
<ooii>hooble <noodle>poo</noodle> zoot <ooii>
<ibo></ibo>
<chibo>1</chibo>
<chibo>145<phoon>ixiy</phoon>ttr</chibo>
</blah>
the xsl would just read all those bizzaro tags without me having to name them indervidualy?
Thanks.

Hi,
How can i remove a table if the date it contains is older than 30 days from an xml file using xsl?
This is how the xml file looks like:
<root>
<table>
<id> 0 </id>
<date> 20060404 </date>
</table>
<table>
<id> 1 </id>
<date> 20060822 </date>
</table>
<table>
<id> 2 </id>
<date> 20060904 </date>
</table>
</root>
Thanks in advance!

If you are using xsl to construct a new xml file, you can chewck in the xsl value of the field
(date), and if it is less than the special one (declare that as a const), move to the next one.
Sorry, I do not remember the exact syntax, but you do have conditions and loops available in xsl

Elina

The xsl file i wanna make should be a stand alone one.
The other xml file is made by another program.
I never worked with xsl. Do you know where i can find some samples codes bout this?

Hello all.
Im trying to validate a single XML file using two schemas in .NET. I cannot change the format of the XML file, which looks something like this:
<br />
<?xml version="1.0" encoding="ISO-8859-1"?><br />
<aaa><br />
<bbb>some text</bbb><br />
<ccc>more elements....</ccc><br />
<InterChangeHead xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="ich.xsd"><br />
<Version>1</Version><br />
<SenderID>xxx</SenderID><br />
<ddd>and so on..</ddd><br />
</InterChangeHead><br />
</aaa>
As you see the <InterChangeHead> refears to 'ich.xsd', this file contains the schema to validate <InterChangeHead> and its children. But i need to control the entire file. I've made a schema file that controls <aaa> and its child elements, but should this file contain a check for InterChangeHead?
In .NET i use the XMLSchemaSet, should i Add the two schemas here? Or will 'ich.xsd' automagically be loaded for me?
I've also tried to make one big schema file which controls everything, but then i get an error on the <InterChangeHead> element, because of the xmlns thingy...
Hope this makes sense to somebody 
Thanks
Arve.

Through trial and error i think i've almost solved this problem. But i still need some help.
This is my example xml file, which cannot be edited:
<br />
<?xml version="1.0" encoding="UTF-8"?><br />
<aaa><br />
<bbb>Text</bbb><br />
<ccc>123</ccc><br />
<ddd xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="xyz"><br />
<eee>text2</eee><br />
<ccc>text3</ccc><br />
</ddd><br />
</aaa><br />
I've made two schemas, first 'aaa_schema.xsd':
<br />
<?xml version="1.0" encoding="UTF-8"?><br />
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="unqualified" attributeFormDefault="unqualified"><br />
<xs:element name="aaa"><br />
<xs:complexType><br />
<xs:sequence><br />
<xs:element name="bbb" type="xs:string" /><br />
<xs:element name="ccc" type="xs:int" /><br />
<xs:any/><br />
</xs:sequence><br />
</xs:complexType><br />
</xs:element><br />
</xs:schema><br />
and 'ddd_schema.xsd':
<br />
<?xml version="1.0" encoding="UTF-8"?><br />
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" elementFormDefault="unqualified" attributeFormDefault="unqualified" xmlns="xyz" targetNamespace="xyz"><br />
<xs:element name="ddd" ><br />
<xs:complexType ><br />
<xs:sequence ><br />
<xs:element name="eee" type="xs:string" /><br />
<xs:element name="ccc" type="xs:string" /><br />
</xs:sequence><br />
</xs:complexType><br />
</xs:element><br />
</xs:schema><br />
What i've done is add a xs:any to the aaa_schema where the ddd element should be.
In the .NET code i've added this:
<br />
Dim arrSchema As XmlSchemaSet = New XmlSchemaSet()<br />
arrSchema.Add(Nothing, New XmlTextReader("C:\temp\aaa_schema.xsd"))<br />
arrSchema.Add("xyz", New XmlTextReader("C:\temp\ddd_schema.xsd"))<br />
But when i try to validate the file i get this message:
"The element 'ddd' in namespace 'xyz' has invalid child element 'eee' in namespace 'xyz'. List of possible elements expected: 'eee'."
What does this mean? I thought the scope of the xyz namespace in the ddd_schema file covered all the child elements, not just the ddd element?
If i edit eee and ccc in the XML file like this:
<br />
<eee xmlns="" >text2</eee><br />
<ccc xmlns="" >text3</ccc><br />
Then everything work, but in the real scenario can't change the XML file.
Anyone?

Hi All,
I am working on VC++ (exe dialog application).. I have loaded the xml file using DOM i;e using a pointer of IXMLDOMDocument and calling the load function of it. Can I know if there are any built-in function or any other alternatives to find the size of the DOM ,before and after loading the xml file??

Is there any algorithms or sample code for finding the difference between two xml files.

Hi
I'm develloping a b2b solution and i need to exchange soap messages with a business partner.
I am now able to post xml with a webservice to their webserver, using httpwebrequest and i also can receive their response.
HttpWebRequest req = (HttpWebRequest)WebRequest.Create("http://www.someurl.com/receive");
I now need the inverse operation. I need to suply them a url so they can post/get their xml messages to me. How do i do that? I've been reading a lot, but i'm confused! i guess i don't need a webservice, i just want them to post their requests like i do, and send them a response like the one i'm getting...
HttpWebResponse wr = (HttpWebResponse)req.GetResponse();
Any help will be highly apreciated..... i'm getting a little desperate here! 
TIA

I am writing an ASP.NET app that reads data from an XML file into an XML control that uses a XSL file to format the XML.
Tags inside the XSL file become HTML on the main page as they should ...but tags that are read from the XML file inside of are output as thier text equivelent (so < becomes <, > becomes >) and so on.
Is there som way of setting the XSL file to output these as tags??
Cheers.
