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

| 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. Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

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

Maybe this is what you want ?
string Str = "<Result><DN>22800661</DN><ID>1</ID><Status><Line>Idle</Line></Status></Result>";
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;

XML is not a prgramming language - it's more a data format.
So…why are you using XML and what are you trying to achieve?Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

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

I try XSL Transfrom on client-side using javascript. My XSL file has a import tag in itself, but it couln't find the another XSL file. I have to excute this transform on Client-Side for
some reason. How can I put the import href content
Here goes my test code. this page written with .NET
Javascript code on the webpage.
function Transform() {
var xsl = new ActiveXObject("MSXML.DOMDocument");
var xml = new ActiveXObject("MSXML.DOMDocument");
xsl.async = false;
xsl.load(dataXmlPath);
xsl.async = false;
xsl.load(styleXslPath);
var data = xml.transformNode(xsl);
}
number.xml (XML Data file)-----------------------
<?xml version='1.0'?>
<data>
<circle>
<radius>12</radius>
</circle>
<circle>
<radius>37.5</radius>
</circle>
</data>
calc.xsl (XSL Style file)------------------------
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:include href="calc2.xsl"/>
</xsl:stylesheet>
calc2.xsl (XSL import file)------------------------
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="data">
<circles>
<xsl:for-each select="circle">
<circle>
<xsl:copy-of select="node()"/>
<circumference>
<xsl:value-of select="radius"/>
</circumference>
</circle>
</xsl:for-each>
</circles>
</xsl:template>
</xsl:stylesheet>
|

|
|
|
|
|
<script>
function Transform() {
var xsl = new ActiveXObject("MSXML.DOMDocument");
var xml = new ActiveXObject("MSXML.DOMDocument");
xml.async = false;
xml.load("number.xml");
xsl.async = false;
xsl.load("calc.xsl");
return xml.transformNode(xsl);
}
alert(Transform());
</script>

yes. it works. thank you.
actually i tested with below script function in order to get a XML Object.
function loadXMLDoc(filepath) {
if (window.XMLHttpRequest) {
xhttp=new XMLHttpRequest();
}
else {
xhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xhttp.open("GET",filepath,false);
xhttp.send("");
return xhttp.responseXML;
}
I thought it's the same but it wasn't..
var xsl = new ActiveXObject("MSXML.DOMDocument");
xsl.async = false;
xsl.load("calc.xsl");
this works fine.

Did you bother to preview this before you posted it, or read it afterwards? I assume not as it is unreadable. Please edit the content and place between <pre></pre> tags using the "code block" button at the top of the edit window.

Hi
I want to implement a webservice with soap and C#
But i am wondering about to change tag as soapenv
How can this be possible?

Hi,
I'm not sure if I understood your problem. You want to implement a webservice with C#.
For the first steps have a look here:
Your first C# Web Service[^]
Or if you want to use WCF take a look here:
Writing your first WCF Service[^]
SOAP is just the protocol used to call a webservice. Fortunately this protocol is transparent for you, since the .NET framework manages everything for you (serialization, deserialization, transport etc.)

How is it possible to import a COM dll from any flavor of unix.
On C++ on windows we can use the #import command to achieve this.
Does the same command help on any unix flavor.
The intent is to use the parsing functionality of msxml [parser.
|
|
|
|
|
|
|
AFAIK, Unix doesn't have the necessary COM infrastructure to let you use COM. So, you're out of luck.
However...there are a lot of other XML parsers out there - I'd suggest looking at libxml2[^], expat[^] or Xerces-C++[^].

Please let me know your comments in below:-
1) Xerces: we need a separate platform/architecture specific binary. This is provided by Xerces.
2) libxml2- Can this be used on unix. I guess its usage is limited to windows.
3) xmllite is another one- One needs to leverage COM technology as interfaces are provided for XML related functions.
4) msxml works on similar way as that in 3)
The requirement is to read a simple xml document in an application.
This application would hold the XML DOM if created in memory in static area as the string that holds the static XML string would be static.

Xerces and libxml2 are both avaiable Windows OR Unix. Xerces is part of the Apache project, libxml2 part of Gnome (I think).
Neither msxml nor XML Lite are available on Unix.
Another cross-platform alternative - RapidXML[^].
I would go for RapidXML, I think.

I have heard that parsers that support XPATH give the best performance and should be used if applications from scratch are used.
IS RapidXML XPATH suppotive?
If no, let me know your comments?
|
|
|
|
|
|

Ummm - well, what are you trying to do with it? XPath is useful for querying an XML document, but does nothing for the performance of the raw parser.
Think about how you're going to get information in and out of the XML file, then make your technology decisions based on those specific requirements.Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Hi
Working with ArcGIS catalog for map files you can create an XML file which contains info about the map.My intention is to gather this data in a DB (PostGreSQL) and create a searching system.The main thing is that searching for the info I want to get as a result the map corresponding to this XML data I searched.Anybody have any clues and give me any orientation because I have little experience with XML.
Thank you in advance
Best regards
Endri

Maybe [this] XLINQ(LINQ to xml) tutorial will help you get the data from the XML file.

Rather than use a database (which might well not be a good match for hierarchical XML data), you could consider using XQuery[^]?
