Hi,
If you are using the latest version of the .Net framework then this task can be performed easily using LINQ.
Below is an example of what you are trying to do in C#:
XDocument servers = XDocument.Load(@"C:\server.xml");<br />
<br />
var q = from c in servers.Descendants("server")<br />
orderby (string)c.Element("con_id") ascending<br />
group c by (string)c.Element("con_id");<br />
<br />
foreach (var con_id in q)<br />
Console.WriteLine(con_id);
Sorry, I don't have a version of this in VB.Net!
Clean code is the key to happiness.

Hello everybody,
I'm hoping someone would have done this before; because I run into a need for something similar fairly frequently;
I'd like a generic XSLT that performs the following translation
--Input XML
<?xml version="1.0" encoding="utf-8"?>
<config>
<parent id="parent1">
<item id="item1" name="Foo" attr="SomeOtherAttr"/>
</parent>
<child id="child1" inherits="parent1">
<item1 id="item2" name="NewItem" someOtherAttr="YetMoreAttributes"/>
</child>
</config>
--Output XML
<?xml version="1.0" encoding="utf-8"?>
<config>
<child id="child1" inherits="parent1">
<item id="item1" name="Foo" attr="SomeOtherAttr"/>
<item1 id="item2" name="NewItem" someOtherAttr="YetMoreAttributes"/>
</child>
</config>
--
You can see this models inheritence in traditional languages, it would increase the flexibility of my XML configuration significantly. But writing XSLT is such a paradigm shift it's difficult to imagine the XSLT transform to do this.
If anyone can point me at existing/similar code (eg, xslt merge element) or if any of you xslt gurus have a complete implementation already handy. That'd be great.
Thanks,
Matthew.

hi
i want to parse an XML file and extract the fields.is theer any generic parser in VC++ 8 (or even C++) so that even if i add one more tag to my XML file with little modification the program should work.
thnx in advance......

If you are considering using XML in your software I strongly urge you to spend some time learning the XML technology space before making decisions about how your going to use XML in your software. This might prove a sizable learning curve since the XML space is quite large now.
You could start here[^] but I don't suggest you consider that sufficient.

I need to add an xml-node to my xml file, which later i will validate. Is there any way to know the exact location where i need to add that node so that validation does not fail? 
Thanks in Advance.

I work primarily with C++ and trying to get a handle on XML. Consider the following class of data:
classA
{
CString name;
int widgits[3];
}
Lets assume the data for the items in the class is:
name = "Bob"
widgits = {1,6,9}
If I was to create an XML file to hold data such as that above, how would the array of widgits be represented?
Would it look something like this?
<data>
<name>Bob</name>
<widgit>1</widgit>
<widgit>2</widgit>
<widgit>3</widgit>
</data>
It doesnt seem that having 3 child elements named "widgit" under the parent named "data" would be correct. Afteral how would it get read back in correctly?
Any help or keyword that I could use for a search would be appreciated. Even a good book on the subject !
Thank you for your help !

It would be more like:
<data>
<name>Bob</name>
<widgits>
<widgit>1</widgit>
<widgit>2</widgit>
<widgit>3</widgit>
</widgits>
</data>
since the widgets element would serve as a container (array) of widgets.

Yes basically it is. Sometimes people or systems prefer a more verbose representation but the same basic principle applies:
<data>
<name>Bob</name>
<widgetList>
<widgit>1</widgit>
<widgit>2</widgit>
<widgit>3</widgit>
</widgetList>
</data>

sir plz suggest me how to read xml using javascript?
|
|
|
|
|
The browser must supply support for working with XML. In Internet Explorer you can use MSXML and the XML DOM. The internet is full of javascript examples for that subject. I don't know how the other browsers support it. Sites like TopXML, W3Schools, Mozilla and others probably have all sorts of information on the subject.

Dear all,
I got an XML like this:
<colleagues>
<colleague branchid="NH" dept="IT">
<name>Aluis</name>
<email>tungdt@ssi.com.vn</email>
<phone areacode="02" ext="1604">123456789</phone>
<mobile>0983934645</mobile>
<fax></fax>
<comp ipaddress="192.168.2.5">IT11</comp>
</colleague>
...
</colleagues>
here is code that I load XML to DataGrid:
<code>
private void loadData(string xmlsource)
{
try {
// Initialize Component and other code here
// Create an XmlDataDocument object and read an XML
XmlDataDocument xmlDatadoc = new XmlDataDocument();
xmlDatadoc.DataSet.ReadXml(xmlsource);
// Create a DataSet object and fill with the dataset
// of XmlDataDocument
this.colleagueList = new DataSet("Colleague List");
this.colleagueList = xmlDatadoc.DataSet;
// Attach dataset view to the Data Grid control
this.lstColleague.DataSource = this.colleagueList.DefaultViewManager;
this.lstColleague.NavigateTo(0, "colleague");
} catch(Exception e) {
throw e;
}
}
</code>
but all the attributes in <phone> node, and <comp> node were not showed.
Please help me how to display all information in one view...
Regards, </comp></phone>

Hi guys,
I create a xml file like this by program:
<condition>disp='1'</conditions>
<item>
<disp> 1 </disp>
<otheritem> f</otheritem>
<item>
<item>
<disp> 2 </disp>
<otheritem> w</otheritem>
<item>
<item>
<disp> 3 </disp>
<otheritem> w</otheritem>
<item>
I use xslt to transform this xml file to html.
But I don't want to show some items, such as, when disp='1', I don't want to show it to users.
In here, the condition is variational. Maybe it's disp!='4', maybe it's otheritem = '53g'.
when I show the items with xslt, how to filt these items?
<xsl:for-each select="/items/item[???]">
I try to add the condition to the xml file, and get it in the xslt. But it can't work normally. Can anyone give me any suggestions?
Thanks & regards.

Also I have one more problem in one of attribute of an xml item there is complex datatype say
< property id="status" title="Status" type="Choice" >
< choices>
< choice > Draft </choice>

Hi all,
I have a XML (xsd designed/based). My client gave me the new version of XSD which modified than earlier one. He needs the xml to be generated on this XSD progammatically. So now the query is that Is there any tool using which i can migrate from one version to other version of XSD. when i put my old xml in that tool and new xsd then the output will be modified xml with may be dummy data. this new xml is supporting the new xsd of course!
If anybody can help me in this regard, please help me !!
Regards,
Jitin

You seem to be missing the aspect of conversion wherein something or someone must decide what data goes where. I doubt you will find any tool that will magically make that decision for you.

I transformed an XML file as follows:
**** original XML ****
<?xml version="1.0" encoding="utf-8"?>
<Data xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<pages>
<ele0>
<pageName>Test</pageName>
</ele0>
</pages>
</Data>
******* Transformed XSL *****
<?xml version="1.0" encoding="utf-8"?>
<main-menu-list>
<pageName pageName="Test" />
</main-menu-list>
**** XSL ***
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<main-menu-list>
<xsl:for-each select="//Data/pages/*">
<xsl:element name="pageName">
<xsl:attribute name="pageName">
<xsl:value-of select="pageName"/>
</xsl:attribute>
</xsl:element>
</xsl:for-each>
</main-menu-list>
</xsl:template>
</xsl:stylesheet>
However, I would like to transform any XML document as above without naming a specific element/attribute.
I found this XSL for starters but am having difficulty representing the element value in the attribute:
<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>
<xsl:template match="pageName">
<xsl:element name="{name()}">
<xsl:for-each select="@*">
<xsl:attribute name="{name()}">
<xsl:value-of select="."/>
</xsl:attribute>
</xsl:for-each>
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Any ideas?

I'm not sure I understand. You want to transform any element into an element of the same name with an attribute of the same name with the attribute value being the value of the child text node of the original element? I can't begin to understand what problem that solves but you need your match value to be "*" to have it transform "any" element.

My task is to create xml-files based on different schemas. The schema files are quite big approx 4000 rows. The contents of the files are stored in our database. I know how to validate, but I am puzzled with file creation process. I need information about how to solve it in a time efficient and flexible (schemas may change now and then) way. Is there a best practice way or are there support tools available? I use Visual studio as development platform.
thanks all
