Hi Friends,
I want to learn XML but really confused where to make a start. The available knowledge on net is so much that it is difficult for a new babie to make a start.
Can someone please suggest how shall I make a start. I am looking for some guidelines to be followed in sequence like
1. Basic XML
2. Schemas
3. Parser etc..
I hope you get my point.
Any help is appreciated.
Thanks in Advance

hi there,
I've got good news  basic XML is very easy to learn. Schemas are bit harder, while *parsing* XML is again relatively easy task (unless you need really optimal performance, maybe).
For basic XML, try W3C Schools[^]. From same site (http://www.w3schools.com[^]) you can learn about schemas and much more...
There are some XML parsers here on CodeProject. Just search...
Oh wait  You actually don't want to write XML parser, do you?  You can use MSXML (ActiveX AFAIK) or System.Xml.XmlReader (.NET framework) or whatever parser you buy/download. Is this your question?
hope it helps. You can come back anytime and ask...
p.s if you are good at reading specifications, see http://www.w3.org/XML[^]

Hi,
I'm trying to change the values of an attribute and saving the xml file. I'm able to change the attributes value and while saving it is not. Following is the code I have written. Please reply ASAP if anyone know about this.
var xml_doc= new ActiveXObject("Microsoft.XMLDOM");
xml_doc.async = false;
xml_doc.load("test.xml");
var purposes = xml_doc.getElementsByTagName("Purpose");
var iLength = purposes.length;
for (i = 0; i < iLength; i++)
{
purpose = purposes.item(i);
attri = purpose.getAttribute("PurposeCodeDescription");
switch(attri)
{
case "Construction-1st Home" :
purpose.setAttribute("PurposeCodeDescription", "xcvxcvxvxcv-1st Home");
break;
case "Purch New Home Other-Not 1st Home" :
purpose.setAttribute("PurposeCodeDescription", "Purch zcvzxcvxcvxcvxcvxc Home-Not 1st Home");
break;
}
}
for (i = 0; i < iLength; i++)
{
purpose = purposes.item(i);
attri = purpose.getAttribute("PurposeCodeDescription");
document.write(attri + "<br>");
}
xml_doc.save("test.xml");

I am having trouble doing this. Would appreciate anyone's help on this.
I create a datatable with rows, and would like to generate an XML file everytime a new record gets added.
Is the following code completely off?
DataRow rowParts = dtParts.NewRow();
rowParts["PartID"] = PartID ;
rowParts["Quantity"] = Qty ;
dtParts.Rows.Add (rowParts);
DataSet ds = new DataSet();
ds.Tables.Add("Parts");
ds.WriteXml ("\\Program Files\\CycleInventory\\Inventory.xml") ;
Thanks.

Is there a way to get the current system date using XSL? I don't merely want to format an existing date, I want to dynamically create a line of output that reads "created on: {current date}" without having to go into my XML file and enter the current date manually.

Hi,
I think the only way to do this is to pass in the date and pick it up in your stylesheet as a global parameter using xsl:param.
The way you pass parameters in to the stylesheet is processor specific, so for instance in .Net there is a XsltArgumentList class.

Thanks Phil!
You hit the nail right on the head. I was working on a stylesheet transformation for C#'s XML documentation feature as a way to teach myself XSL.

hi,
your XML is not even valid! According to XML spec.[^] you have to escape & as "&", or write it only in CDATA or comment.
In .Net Framawork, you can use <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwebhttpserverutilityclasshtmlencodetopic1.asp">HttpServerUtility.HtmlEncode</a>[<a target=_blank title='New Window' href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpref/html/frlrfsystemwebhttpserverutilityclasshtmlencodetopic1.asp">^</a>] from System.Web namespace.
Solution in our case is something like
tmp_Message = System.Web.HttpServerUtility.htmlEncode("Joe&&&&&&&&&&&redroom");

AFAIK you have to write your own.

I am having an issue. I need to perform an xslt on an xml document however the document contains xml encoded inside the xml (see sample below). I need to know how to pull out the inner xml so I can parse it from inside an xslt transform. Any help is greatly appreciated.
(code)
<?xml version="1.0" encoding="utf-8" ?>
<Thomson.Financial.T1Link.APIResponse>
<Variable Name="_result" Value="<ALL_RESULTS request="10054"><SEQUENCE id="1"><BETALink_XMLResponse><HeaderInfo RecordCount="1" /><Warnings /><Data><row><BetaLinkUserId>895288</BetaLinkUserId><FirmNo>990</FirmNo><SubNo>990</SubNo><EntityKey>39172390-D9FC-4B4D-9744-8B168F0B3842</EntityKey></row></Data></BETALink_XMLResponse></SEQUENCE></ALL_RESULTS>" Value_Type="System.String" />

Hi,
As it appears here, your xml is not valid. The "<" character cannot appear within an atribute value, unless you escape it as < Also you have " charaters embedded within an attribute value that uses the same " character to enclose the attribute value, you could escape the inner quotes as "
You need to fix the xml before you can look at the xslt. Are you able to change the xml structure?
If the attribute must contain xml, then you will have to escape the appropriate characters, after that you will be able to use the value-of element to retrieve the escaped xml. At that point, I guess you would need to 'un-escape' it.
Sounds complicated...
Good Luck,
Cheers

Didn't he write "the document contains xml encoded inside the xml". I'd guess it is escaped. But my English is self-thought ( in computer terminology), so word "encode" has only one meaning to me ...

agree. I think it's plain bad xml structure. I'd move "inner" xml out of attribute. Attributes are not meant to contain hierarchical things... Use them for atomic data seems the best way to me. I'd move that xml to CDATA element inside current variable or what element is was.
other ideas?

You're probably right.  I must admit to having been somewhat surprised to see xml like that.

Not really. If the xml structure can be changed then a CDATA section sounds like just the right approach.
