Hi there,
On the project I'm currently busy I have the following issue:
We are receiving SOAP 1.1 messages (according to SOAP 1.1 schema) and need to output messages conforming to a schema in another namespace. The structure of both schema's are identical as you can see below.
SOAP schema instance:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Header>
<SomeHeader/>
</SOAP-ENV:Header>
<SOAP-ENV:Body>
<SomeElement/>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
Output message schema instance:
<BLA:Envelope xmlns:BLA="http://SomeOtherNamespace">
<BLA:Header>
<SomeHeader/>
</BLA:Header>
<BLA:Body>
<SomeElement/>
</BLA:Body>
</BLA:Envelope>
Okay here the challenge:
We're in need for a high performance transformation of these two messages. The way we would love to see it is having the transform implemented completly streaming.
- input stream read when output stream is being readon (pull).
- low memory footprint.
Environment: C# on .NET platform.
Options I'm considering:
1. Implementing a streaming namespace replacing XML text reader.
A stream is read by a custom XMLTextReader that replaces the xml namespace declaration so the message is implicetly converted.
The problem with this solution is that the streaming XML text reader does not provide a way to generate an output stream. Using the XMLTextWriter object and WriteNode method reads the entire message and puts out the message to the underlying stream. But this is push technology and the process is blocked until the reading and writing is done.
2. Using streaming XSLT (pull)
I have not been able to get this to work. Anybody can give me a hand?
3. Am I overlooking something? Please let me know.
Kind regards for your patience and hopefully a good solution.

Downlaod a trial version of XMLSpy[^] - that can generate XML instance documents from XSDs and DTDs.
Make sure it's a trial of the Enterprise or Professional version - the other version doesn't do it.

Ok, I know I will get reamed for this XML-newbie question, but here is what I want to know.
Can I have this
<br />
<dataItem_00><br />
<name>somename</name><br />
<type>sometype</type><br />
<br />
<dataItem_01><br />
<name>sub_name_1</name><br />
<type>sub_type_1</type><br />
<dataItem_01><br />
<br />
<dataItem_01><br />
<name>sub_name_2</name><br />
<type>sub_type_2</type><br />
<dataItem_01><br />
</dataItem_00><br />
Basically, I am uncertain about the reuse of tags within nested "blocks"
Thanks,
Johnny

using dataItem__xx is stupid, but what you're doing is totally legal, that's how you'd have a list of items all the same, which have subitems.

I am gong to nit pic here.
reusing tags is not a problem.
Properly terminating the blocks is and the sample you show does not.
None of your dataItem_01 elements (you have 4 as shown not 2) are terminated.
I do not mind getting old. It beats all the other options that can think of.

hi sudheer,
is it .NET? If yes, look on System.Xml namespace, expecially classes System.Xml.XmlTextReader or System.Xml.XmlDocument on MSDN.com, there are lot of exmaples how to read XML files.
If it's not .NET, what is it? 
best regards,

Hi,
I need an application which displays a tee view of an XML document.
I have seen many applications which do the same. But I need to draw the Tree with the element text and with out attributes node in the tree.
Let me make it clear..
Here is snippet of the xml file.
--------------------------------------------------------------------------------
- <device name="TenGiPHY" deviceversion="1.0.0.1" productid="24622.10.0.1" fileversion="1.0.2.2">
- <group name="PMA/PMD">
- <folder name="MDIO">
- <register name="PMACTR1" length="16" address="0x10000" resetval="0x2040" access="rw">
<longname>PMA Control Register 1
<value>0x0
- <element name="RES" offset="15" length="1">
<longname>PMA reset
<desc>This bit remains set (1) while reset is in progress and is cleared (0) automatically as soon as reset is completed. The first MDIO access following an MDIO reset must be an address frame. Access to this bit affects the entire device.
<modified>false
<state text="Normal operation" value="0x0">
<state text="All registers within the TenGiPHY-L are set to their initial state." value="0x1">
----------------------------------------------------------------------------------------
The tree I need is
TenGiPHY
|
|_PMA/PMD
| |
| |_MDIO
| | |_PMACTR1
| |_NextFolderName
|
|_Next group name
and so on..
But I have the least idea to do this.
Could anyone help me?
Thank you,

Sorry, some lines are missing..
I am giving the xml lines here again..
<!DOCTYPE device (View Source for full doctype...)>

Has anyone else had any issues with the Dataset.SaveXML method??
I have found that with this xml file
<database xmlns="http://tempuri.org/Database.xsd">
<DBTable>
<name>vwAppointment</name>
<selectall>false</selectall>
<selectbykey>false</selectbykey>
<update>true</update>
<insert>true</insert>
<delete>false</delete>
<DBFields>
<name>pkId</name>
<primarykey>false</primarykey>
<datatype>int</datatype>
<nullable>false</nullable>
<length>4</length>
<precision>10</precision>
<selectby>-1</selectby>
<updateby>false</updateby>
<deleteby>false</deleteby>
</DBFields>
<DBFields>
<name>AppointmentType</name>
<primarykey>false</primarykey>
<datatype>varchar</datatype>
<nullable>false</nullable>
<length>30</length>
<precision>30</precision>
<selectby>-1</selectby>
<updateby>false</updateby>
<deleteby>false</deleteby>
</DBFields>
</DBTable>
</database>
and this xslt
<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="/">
<xsl:for-each select="database/DBTable/name">
<<xsl:value-of select="*"/>Table>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
The transform does not work, however if i remove this attribute
xmlns="http://tempuri.org/Database.xsd"
the transform will work (well work to some extent with my dodgy xpath queries).
Why does this happen? how can i get around this? is there an xslt setting i need to change?
Thanks for your help

Hi there.
I have an SQL XML template residing on a web server which takes a parameter (japanese characters) and calls a stored proc.
If I hard code the japanese parameter into the XML file, I can execute the stored proc and have records returned.
However, the XML template is called from an ASP page, also on the web server, using the ("Msxml2.ServerXMLHTTP.4.0") object. I call the template using the following code:
-------------------------------------------------------------------------
Set SearchObj = Server.CreateObject("Msxml2.ServerXMLHTTP.4.0")
templateURL = "http://localhost/xmldir/xmltemplate/global_search.xml"
Param = "?PRIM_NAME=" & JAPANESE_NAME
SearchObj.open "GET", templateURL & Param, False
SearchObj.send
-------------------------------------------------------------------------
Variable 'JAPANESE_NAME' is a company name in japanese (ie. double byte).
Every other instance of double byte characters are handled fine by my ASP and XML, however it is only when I am trying to send some double byte characters as arguments to this template that it fails.
I have also tried passing the japanese data to the XML template manually via a URL call....but it also fails.
My XML template looks like this:
----------------------------------------------------------
<root xmlns:sql="urn:schemas-microsoft-com:xml-sql" sql:xsl="global_search.xsl">
<sql:header>
<sql:param name="PRIM_NAME">
<sql:query>
exec my_stored_proc @PRIM_NAME
----------------------------------------------------------
I can run the stored proc through query analyzer and give it some japanese characters as arguments and it works fine.
Can SQL XML templates handle double byte data passed as a parameter or does it have to be hard coded in the file?
Any help would be appreciated

Greetings,
I have a xsl file which transforms my xml file into a html page, and when I use it as a style sheet for my xml data it works fine. But when I use XslTransform called from a c# application it doesn't transform the file correctly it replaces my java script "<" symbol with "<" symbol.
I have this code in a "

hi,
replace "<" with "<；". Yes, in JS. It will render/transform (?) correctly for browser. Than it should be fine. Also, you should (or even must, I am not sure) call XslTransform constructor that take XmlResolver as a parametr. (I don't know if it's really needed bt other constructors are obsolete )

Thanks for the reply,
It still didn't work, it just left the &.l.t.; (kept formating it as <) in the javascript code. I saw a code blurb where they suggested commenting out the "<
for(int index=0;index&.l.t.;10;index++)
{
... Do something here.
}
}
//]]>;
</SCRIPT>
...
...
It doesn't make any sense why this isn't working.

hi,
belive me, it works maybe remove <![CDATA]> ?I am working on something similar and it is working!
here is (simplified) my code:
<br />
<script language="JavaScript"><br />
function ShowSelect(o)<br />
{ <br />
var x2 = document.getElementsByTagName('div');<br />
for(i=0;i<x2.length;i++)<br />
{<br />
<br />
}<br />
}<br />
</script><br />
</head><br />
<body><br />
<br />
try<br />
{<br />
XslTransform xt = new XslTransform();<br />
xt.Load(StylesheetURL);<br />
xt.Transform(SourceURL,ResultURL,new XmlUrlResolver());<br />
}<br />
catch(Exception ex)<br />
{<br />
<br />
throw;<br />
}<br />
What I missed? This is definitely working in my app. I can't send you my original code cuz my boss wouldn't be happy about it

Thanks David!
Your C# snippet worked great! Maybe it was because I was using the obsolete constructors or something.
Thanks again!!

the reason it does not work is that your html is not valid....
you don't have to escape < if you have specificied the out as html and the document root is html.
your code does not work as I suspect your "html" tag is in upper case!

Hello,
Iam a beginner in .NET and please help me in doing this:
I have a node like this:
<root>
<pleasehelp>100</pleasehelp>
<firstchild>
<pleasehelp>200</pleasehelp>
</firstchild>
<secondchild>
<pleasehelp>200</pleasehelp>
</secondchild>
</root>
I want to add an attribute to <pleasehelp> only under
<secondchild>, so i want something like this...
<secondchild>
<pleasehelp myattribute>200</pleasehelp>
</secondchild>
I learnt that attributes can be added only to elements.
Is there any method of traversing, using an Xpath query and getting that element alone(not node), so that i can add attribute to element directly, without loading that node into XmlDocument object and finding element and then adding attribue to it.
Please Help me..thanks in advance..
Regards,
Manivannan.P

hi,
you can add attribute directly like this
<secondchild text="First">
and u can get help to search node from following code.
XmlDocument doc = new XmlDocument();
doc.Load(Server.MapPath("XYZ.xml"));
XmlNode element;
XmlElement root = doc.DocumentElement;
// this line will get the node with the id
attributes matching with the
// selected category's ID.
element = root.SelectSingleNode("descendant::yournode[@text='First']");
// create a new node and append it under the selected category's node.
XmlElement node = doc.CreateElement("yournode");
node.SetAttribute("text","urstring");
node.SetAttribute("id","urvalue");
element.AppendChild(node);
// saving the updations in XML File.
doc.Save(Server.MapPath("XYZ.xml"));
Regards,
Manoj

If I have an XML file that contains classic "Contact" or "Customer" or "Purchase Order" data used in examples out there, is there a way I could, from within this same XML file provide the user with an interface to edit this data in a webbrowser?
This should be such that, for example, the user would call:
http://myserver.com/thexmlfile.xml
and be presented with a form (editable fields) instead of the default XML view of data that internet explorer provides.
Is this possible?

I am new to the System.Xml, I am converting the code existing in MSXML parser code to System.Xml in unmanaged C++.
I am able to load the file with the Load() function, and I am getting the validate error from the catch block. there is no problem in loading the xml documet into the "m_docPtr" this is System.Xml.XmlDocument type.
After loading the xml document into "m_docPtr", I will change the values of some child elements. Now I want to validate the document again with the new chages.
In MSXML parser Validate() methode in the document class to do the above, Can I get the similar method or some procedure with System.Xml classes.
Thanks.
