Here's a short C# program that will read the bit of XML you want and write it to the console.

using System.Xml.XPath;
using System.IO;

namespace ConsoleApplication1
{
   class Program
   {
      static void Main(string[] args)
      {
         // The XML file is specified as the first command line argument
         // imagePath will contain the image path contained in the XML file
         string imagePath = new XPathDocument(new StreamReader(args[0])).CreateNavigator().SelectSingleNode("/image/img").Value;
         System.Console.WriteLine(imagePath);
      }
   }
}

I've used XPath to navigate to the required element in the XML file (that's the .SelectSingleNode("/image/img") bit) and read the text there (the .Value bit). Simples.

You need to give a command line argument that specifies the XML file...the code comments DO say that....

Multiple group using Muenchian Method [modified]

I have the following input XML. I want to group all unique Code/ID combination.

<List>
 <Section>
  	<Code>AA</Code>
  	<ID>11</ID>
 <Section>
 <Section>
  	<Code>AA</Code>
  	<ID>11</ID>
 <Section>
 <Section>
  	<Code>CC</Code>
  	<ID>11</ID>
 <Section>
 <Section>
  	<Code>AA</Code>
  	<ID>22</ID>
 <Section>
 <Section>
  	<Code>AA</Code>
  	<ID>11</ID>
 <Section>
<List>

So result should be as shown below.

<Code>AA</Code>
<ID>11</ID>

<Code>CC</Code>
<ID>11</ID>

<Code>AA</Code>
<ID>22</ID>

Im using the Muenchian Method. Currely my XSL (below) is grouping by Code (and not Code/ID combination)

<?xml version="1.0" encoding="UTF-16"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var" exclude-result-prefixes="msxsl var" version="1.0" xmlns:ns0="http://A4C.Interface.HRP.Payroll.Schemas">
	<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />

	<xsl:key name="CCids" match="/List/Section" use="Code"/>

	<xsl:template match="/">
		<xsl:apply-templates select="/ns0:Payroll" />
	</xsl:template>
	<xsl:template match="/ns0:Payroll">
		<ns0:List>
			<xsl:for-each select="/List/Section [generate-id(.)=generate-id(key('CCids',Code))]">
				<Section>
					<Code>
						<xsl:value-of select="code/text()" />
					</Code>
					<ID>
						<xsl:value-of select="id/text()" />
					</ID>
				</Section>
			</xsl:for-each>
		</ns0:List>
	</xsl:template>
</xsl:stylesheet>

How do i get this to use a Code/ID combination? I tried nested for-each loop but no luck. Thanks

Firstly, your key needs to have an expression which reflects what you want to retrieve:

<xsl:key name="CCids" match="/List/Section" use="concat(Code,'|',ID)"/>

And then you need to use that same expression when accessing items referenced by the key.

Oh - and in addition, I would suggest not using a for loop - it's not idiomatic XSL. Here's the file I'd use:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var" exclude-result-prefixes="msxsl var" version="1.0" xmlns:ns0="http://A4C.Interface.HRP.Payroll.Schemas">
   <xsl:output omit-xml-declaration="yes" method="xml" version="1.0" encoding="utf-8"/>

   <xsl:key name="CCids" match="/List/Section" use="concat(Code,'|',ID)"/>

   <xsl:template match="/">
      <ns0:List>
         <xsl:apply-templates select="/List/Section [generate-id(.)=generate-id(key('CCids',concat(Code,'|',ID)))]"/>
      </ns0:List>
   </xsl:template>
            
   <xsl:template match="Section">
      <Section>
         <Code>
            <xsl:value-of select="Code/text()" />
         </Code>
         <ID>
            <xsl:value-of select="ID/text()" />
         </ID>
      </Section>
   </xsl:template>
</xsl:stylesheet>

Deserialize to what? The way in which it's deserialized depends on the type you think it is.

Are you sure this was serialized from .NET? That's not the only way to read and write XML, you know - maybe you should be using an XMLReader and parsing the XML yourself?

I have serialized using XmlSerializer.
I have removed Xml version and namespace information from the XML.
I have changed the root node from
<ArrayOfEnvironmentConfigurations> to <EnvironmentConfigurations>
I want to desrialize this xml.
Thank you.

The answer to your problem is very, very clear - don't mess with the XML that the serializer produces - all of the things you changed are in there for a reason!!!!

Then you should study some of the tutorials here and on MSDN on the use of XML. From the remainder of your question it appears that you are asking for a complete image viewer solution. If you have no idea how to start on this problem then you have a lot of studying still to complete.

Problem with MSXML6 + namespace + XPath

Patrice Espie18-Feb-10 4:57

Patrice Espie

18-Feb-10 4:57

Hi All,

I try to use MSXML with xml files which contains namespaces. But I can't figure out how to do!

Here is an excerpt of my XML file:

<?xml version="1.0" encoding="utf-8"?>
<BENCH xmlns:VODPC_VOD="urn:VODPC:VOD:schema:20060809">
<VODPC_VOD:GRAPH state="running" currentFlowID="1" removeOnExit="FALSE">
</VODPC_VOD:GRAPH>
</BENCH>

When I load the file with MSXML6, no problem.
I try to access node BENCH with XPath "/BENCH" : no problem.
But when I try to access node VODPC_VOD:GRAPH with XPath "/BENCH/VODPC_VOD:GRAPH", I get an exception, which contain no valuable information:

First-chance exception at 0x75ac9617 in XXXXXX.exe: 0xE0000001: 0xe0000001.
First-chance exception at 0x75ac9617 in XXXXXX.exe: 0xE0000001: 0xe0000001.
First-chance exception at 0x75ac9617 in XXXXXX.exe: 0xE0000001: 0xe0000001.
First-chance exception at 0x75ac9617 in XXXXXX.exe: 0xE0000001: 0xe0000001.
First-chance exception at 0x75ac9617 in XXXXXX.exe: Microsoft C++ exception: _com_error at memory location 0x0025dac4..

I set these flags before to load:

m_pXMLDoc->async = VARIANT_FALSE;
m_pXMLDoc->preserveWhiteSpace = VARIANT_TRUE;
m_pXMLDoc->validateOnParse = VARIANT_TRUE;
m_pXMLDoc->resolveExternals = VARIANT_TRUE;

As you can understand, I work in C++. I'm an IT profesionnal since 18 year.

My problem is that I do not know what namespace is used in the file, so I don't want to have to tell MSXML6 what namespaces are used IN THE FILE. I guess it's its job, no ?

If anybody have an idea ...
Thanks a lot

Patrice

Stuart Dootson23-Feb-10 0:10

You have to tell MSXML what namespace prefixes your XPath expressions use. When parsing XML, the parser remmebers the namespace URIs, NOT the prefixes used in the documents. That means that your code has to define the prefix to URI mappings used in your XPaths.

Problem with loading a xml to DataSet

15-Feb-10 23:42

Hi all,

I've xml string and I can load it with XmlDataDocument.LoadXml successfully,
so that OuterXml shows the real xml string. But when I want to load in a dataset, the result dataset has no table(Tables.Count=0).
Typical code is as follows:

...
XmlDataDocument Doc = new XmlDataDocument();

/*
string Str = "<Result><DN>22800661</DN><ID>1</ID><Status><Line>Idle</Line></Status></Result>";
*/

Doc.LoadXml(Str);
DataSet datasetResult = Doc.DataSet;
if(datasetResult.Tables.Count == 0) return;
...

and it returns that means datasetResult.Tables.Count is always 0.

Can anyone help me, what is wrong?

Thanks in advance

System.IO.StringReader sr = new System.IO.StringReader(Str);
XmlDataDocument Doc = new XmlDataDocument();
Doc.DataSet.ReadXml(sr);
DataSet datasetResult = Doc.DataSet;
if (datasetResult.Tables.Count == 0) return;

Using MSXML2.ServerXMLHTTP.4.0 and ASP

tommywick656-Feb-10 4:49

tommywick65

6-Feb-10 4:49

I have an asp page that request data from a remote site (API) via XML.

My code is as follows:

DataToSend = "http://jc.tee.id.com/api/2.0/"& Request("resource") &"?apikey=a0d523ddnfjfjkkfkfkf32c&format=HTML&pret typrint=true&links=resource-path-encoded&request_handler_uri=http%3A%2F%2Fwww.mysit e.com%2Fitems&styles=enhanced"

set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP.4.0")

xmlhttp.Open "GET", DataToSend, false

xmlhttp.setRequestHeader "Content-Type", "application/x-www-form-urlencoded"

xmlhttp.send

Response.Write xmlhttp.ResponseText

This code works fine and returns data with no problem. However on page where the API has AJAX in it, the AJAX doesnt function.

For example, executing my code I pull up a table of contents page:

A | B | C | D | E

apple
adam
aligator
acorn

If I click in the title names, it takes me to the proper URL with no problem. if I click on a navigation letter (which is suppose to execute AJAX on the API side and pull in new titles), it just reloads the page.

I am assuming its because of MSXML2.ServerXMLHTTP.4.0.

I tried switching to 6.0 but this did nothing as well. Am i not able to execute AJAX or something through this remote site??

Any help or insight anyone could give me would be greatly appreciated.
Thanks
