Not with XSD, IMO - you'd need something like Schematron[^]
|
|
|
|

was afraid of that.
thanks for the validation 
is it then common practice to have different node names to start with, and not differentiate by node type?
|
|
|
|
|
Mmmmm - yes, I guess so. Otherwise you leave verification of semantic constraints (such as the one you want to enforce) to a stage *after* XSD validation.

You can't. It goes against W3C's XML specifications.
|
|
|
|
|
i was looking at the following tutorial's last topic Element Naming.
http://www.w3schools.com/xml/xml_elements.asp
it doesn't say anything about this restriction.

Hi there.
Look at section 2.3 of the XML specifications[^]
Of particular interest are rules 4 and 5 which specifies the valid range of XML element names.
Quoting from the Specification:
Names and Tokens
[4] NameChar ::= Letter | Digit | '.' | '-' | '_' | ':' | CombiningChar | Extender
[5] Name ::= (Letter | '_' | ':') (NameChar)*
[6] Names ::= Name (#x20 Name)*
[7] Nmtoken ::= (NameChar)+
[8] Nmtokens ::= Nmtoken (#x20 Nmtoken)*
Both IE and Firefox have XML support, so you could create an XML file containing the element and display the file in the software. It will perform a well-formed check on files with an .xml extension and will return any errors encountered.
Regards, Graham.

Ha! Tricky isn't it...
(Taken from http://www.w3schools.com/xml/xml_elements.asp)
XML elements must follow these naming rules:
* Names can contain letters, numbers, and other characters
* Names must not start with a number or punctuation character
* Names must not start with the letters xml (or XML, or Xml, etc)
* Names cannot contain spaces
belive it or not, '/' (slash) is a punctuation character.
edit: oops, it says only at beginning. So they do miss this rule.

it is just saying names must not start with punctuation, i wasnt starting name with /, i want to just use it like < I / O > and first rule says it can contain other characters.

Hi. I'm using the xsd.exe utility to auto-generate C# classes for my .NET project from an XSD file. The "service" I am using does not have a WSDL, so generating proxy classes from wsdl.exe is not an option.
Does anyone have any experience using the auto-generated classes from xsd.exe? My problem is that in the XSD, I have a complex data entity that is of "type" such and such, and therefore, is not generated as it's own class.
The XSD defines a "complexType_decisionEngineRequest" like this:
<xs:complextype name="complexType_decisionEngineRequest">
<xs:complexcontent>
.
.
.
and later on, a "decisionEngineServiceRequest" element is defined of TYPE "complexType_decisionEngineRequest" like this:
<xs:element name="decisionEngineServiceRequest" type="complexType_decisionEngineRequest">
What xsd.exe ends up generating is a class for the "complexType_decisionEngineRequest", but not a class for the "decisionEngineServiceRequest", which is what I want for my XML base tag. I wish to declare these classes such that my XML that is serialized looks like this:
<decisionengineservicerequest>
....
My question is, is this a case where I should just give up and write my own class, or is there a way to do this with the auto-generated classes from xsd.exe?
Anyone have a similar experience?

Woops, guess I can't include the XML source!
try again...

You can, but you must check " Ignore HTML tags in this message (good for code snippets)".

Hi,
I have a very huge XML file ( around 30 MB in size)..
The problem is i need to search nodes( many of them, basically BFS)
XML file contains data in linear fashion..
now searhing around 30,000 nodes takes long time...
can any one suggest which class could i use here to obtain faster results..
i am confused with all the xml classes .NET provides.. as to which class's object would solve my purpose...
probably some code snippets supporting your answer would be of great help
Thanks

 That's a large amount of XML data! Since its such a large file, I would advise against using XmlDocument or DataSet which will load the entire data into memory. Instead you need to use an XmlReader, which only provides one way access to maximise performance.
I'll quote from MSDN: "Represents a reader that provides fast, non-cached, forward-only access to XML data.".

|

Speaking from personal experience, I would suggest moving the data to a database instead of using XML files that are that large. I did a project that started out by having a pure XML backend but as the files grew I ran into the same problem you are having. We ended up using Access for simplicity and later moved to MySQL because it was a free database our clients could run.
Just my 2 cents.

I think you might want to look at vtd-xml
it is ideally designed to do what you described..

I have an sql table with products

ex: columns
item | categoryPath
product1 | cat1 > subcat1 > subsubcat2
product2 | cat1 > subcat1 > subsubcat3
product3 | cat2 > subcat2 > subsubcat1
... so on
how can i generate a xml-tree from the column categorypath ?
like:
<node>cat1
<node>subcat1
<node>subsubcat2</node>
</node>
<node>subcat1
<node>subsubcat3</node>
</node>

Hi

Please help me

No, I researched this recently.
The support in MS XML 3.0 is for something called XDR.
You need to use MS XML 4.0 or later to validate using XSD.
What would fail on trying to add a schema to schema cache in 3.0 with a 'root node is bad blah blah blah...' exact same code modified to use 4.0 added to schema cache and validated without error.
I've seen better runs in my shorts! - Patches O'Houlihan
