I have had a look round a few sites but could not find a definitive statement on this.
Use the best guess

The dev at the company who provide the web service got back to me saying there should always be a value, and they would of course fix it.

It is valid -- but, the creator of the XSD did not indicate that it was required -- and you have assumed that it is required. If your code cannot tolerate that -- then modify the XSD to make it required and have whoever produces the XML give it a default value....
However, this is simply pushing it off to the side. This is an issue that does not relate to XML per se -- it relates to best practices about defining and validating data.
The XSD defines the structure and rules of XML -- so the designer of the schema must describe the data perfectly and consumers must not make assumptions that are not supported by the XSD.

I have a XML which has list items like
<list type="expl" margin="0">
<li label="(1)">
<p num="n">
<text>
(1) A person
is guilty of an offence if:
</text>
</p>
</li>
</list>
<list type="expl" margin="0">
<li label="(a)">
<p num="n">
<text>
(a) the
person deals with money or other property; and
</text>
</p>
</li>
</list>
The output i need is like
<list type="expl">
<li label="(1)">
<p num="n">
<text>A person is guilty of an offence if:</text>
</p>
<list type="expl">
<li label="(a)">
<p num="n">
<text>the person deals with money or other property; and</text>
</p>
</li>
</list>
</list>
Effectively if List appears as consecutive siblings, and they are of different types (eg, (1)/(a)/(i)) they must be nested inside the previous list item.

This is not the document you want for figuring out CRUD. You need the XSD to do that properly. You could guess and as long as the database column names matched you *might* be able to guess correctly, but...I would not be helping you if I recommended that you do that.
If you can write your own query to select a row and if you also had access to ADO.NET -- you could have the table tell you its schema and then the query could be written properly.
This method that you are using -- is not a great idea -- you can have some success in doing it, but not for long and it is very likely that you will manage to put a row in the database that will be junk data because you do not know the schema -- you are just making blind CRUD operations.
A better choice might be stored procedures because you can just provide the parameters from the client side. At any rate, the less you count on being smart on the client side, the better off you will be.

Before you read on, this is not about checking for valid XML syntax or schema.
I would like to be able to check if the user is opening an XML file that has data for my application only. If they try to open any other XML file the application should warn them.
The XML file data is serialized via XmlSerializer.
Thanks,
Mark

Add some kind of identifier for your application, perhaps also including a version number.

Does such a thing require adding a new namespace?

OK, I'd be first to post a link to Parsing Html The Cthulhu Way
[^] if anyone suggests Regular Expressions, but I have a problem using an XmlDocument (and therefore XPath) with an HTML file I'm downloading.
The page is a list of files to download -- I need to extract the hrefs from the as, obviously I'd prefer to use XPath to do that.
0) The file doesn't contain an opening <HTML> tag (it does have a closing </HTML> tag  ) -- I can tack one on, that's not a big deal.
1) It contains at least one entity (and possibly other entities) and the XmlDocument doesn't like that. 
So I need options, people!
I can summon Cthulhu. 
I can use Regular Expressions to replace any offending entities and then feed the result to an XmlDocument.
What other options might there be?

HTML != XML
Use the HTML Agility Pack[^] instead.

Ah, sooooo... let the summoning begin!
Oh, mighty Cthulhu! Wise and terrible! I ask your assistance as my days have been blighted with some gnarly HTML! Please, oh lord, come smite the bare buttocks of the wretch who hast wrought this travesty. I will repay you with a pint of bitter. Not a measly USian pint mind you, but a proper Britsh pint.

No need to make that call to R'lyeh yet; the HAP makes parsing an HTML document simple:
HtmlDocument doc = new HtmlDocument();
doc.Load(@"path\to\your\file.htm");
foreach(HtmlNode link in doc.DocumentElement.SelectNodes("//a[@href"])
{
string url = link["href"].Value;
Fhtagn(url);
}

If I take data (1,2,3,a,b,c,..) and I put it in XML form
(<a>, < b >, <c>) does that mean that data becomes information because of XML? Does XML turn data into information by representing it in tags?
I am also reading here in a slideshow: "In JDOM, every XML tree is approached as a document even though the content has nothing to do with documents". I looked up the definition of 'document' on dictionary.com and it states that a document is meant as being informative. 'informative' means 'to convey information'. Then, if the purpose of XML is to represent data into information, why does the content of an XML tree supposedly not have anything to do with a document and therefore nothing to do with information? This is confusing. Perhaps the author of that slideshow was using different semantics than I have in my mind right now.
Any thoughts on this?

I actually view XML documents as a datatable, and in fact you can store a datatable to XML format by the ToXML command.
|
|
|
|
|
Usually we meet various files like XLS,txt and others when preparing for a report, are their any easy ways or tools to make the format conversion more directly and easily？

XML is the data container; XSLT is the document that transforms the XML into some other data container -- its purpose is to do what you are asking. XSD is the schema -- it defines the format of the XML so that consumers can correctly instantiate objects that are contained in the XML document.
People are not seeming to understand the difference or the purpose of XML/XSD/XSLT -- and that is somewhat tragic because it is the best way to do things and maintain validity of data through disparate systems.

Hi!I have a scenario.a company ask me to include a payment system in my application and this is the requirement :
a) we need you to provide us a location (in the form of a URL) which we can use to hit your server
b) we will send information regarding a payment transaction in the following XML format to your server at the URL address:
Request sent from ABC Company to My Company
="1.0"
<!DOCTYPE COMMAND PUBLIC "-//Ocam//DTD XML Command 1.0//EN" "xml/command.dtd">
<COMMAND>
<TYPE>PAYMENT</TYPE>
<COMPANYNAME>Luku</COMPANYNAME> <CUSTOMEREFID>refernceNumber</CUSTOMEREFID>
<MSISDN>msisdn</MSISDN>
<AMOUNT></AMOUNT>
<TXNID></TXNID>
<STATUS></STATUS>
</COMMAND>
c) on your side, we need you to interpret the information provide in the XML string, take whatever actions need to be taken on your platform, and then give us a response with the results of your actions in the following format:
Asynchronous response sent from My Company to ABC
<?xml version="1.0"?>
<!DOCTYPE COMMAND PUBLIC "-//Ocam//DTD XML Command 1.0//EN" "xml/command.dtd">
<COMMAND>
<TYPE>GBPHANDLER</TYPE>
<TXNID>BP120522.1117.C00001</TXNID>
<REFID>1357</REFID>
<RESULT>TS</RESULT>
<ERRORCODE>ERR123</ERRORCODE>
<FLAG>Y</FLAG>
<CONTENT>Content For Sending SMS</CONTENT>
<MSISDN>09899847486</MSISDN>
<COMPANYCODE>Luku</COMPANYCODE>
</COMMAND>
I have tried to resolve,this is my xml file I have created:
<?xml version="1.0"?>
<!DOCTYPE COMMAND PUBLIC "-//Ocam//DTD XML Command 1.0//EN" "xml/command.dtd">
<COMMAND>
<TYPE>GBPHANDLER</TYPE>
<TXNID>BP120522.1117.C00001</TXNID>
<REFID>1357</REFID>
<RESULT>TS</RESULT>
<ERRORCODE>ERR123</ERRORCODE>
<FLAG>Y</FLAG>
<CONTENT>Content For Sending SMS</CONTENT>
<MSISDN>09899847486</MSISDN>
<COMPANYCODE>Luku</COMPANYCODE>
</COMMAND>
and this is my .dtd file :
<?xml version="1.0"?>
<!DOCTYPE COMMAND PUBLIC "-//Ocam//DTD XML Command 1.0//EN" "xml/command.dtd">
<COMMAND>
<TYPE>GBPHANDLER</TYPE>
<TXNID>BP120522.1117.C00001</TXNID>
<REFID>1357</REFID>
<RESULT>TS</RESULT>
<ERRORCODE>ERR123</ERRORCODE>
<FLAG>Y</FLAG>
<CONTENT>Content For Sending SMS</CONTENT>
<MSISDN>09899847486</MSISDN>
<COMPANYCODE>Luku</COMPANYCODE>
</COMMAND>
Now I am stack on that level.My question is this Which url I need to provide? how to make a generated xml file?Am I need to store this information into a database? because the system need to verify an incomming request everytime a customer need to make a payment by verifying a reference code generated from the system and check if it is matching the amount of a product he want to buy.Please need an idea.I am spending a lot of time learning xml but I am not finding the answer.By the way I am using c#.net.Thanks!
