XML attribute vs XML element
At work we are being asked to create XML files to pass data to another offline application that will then create a second XML file to pass back in order to update some of our data. During the process we have been discussing with the team of the other application about the structure of the XML file. The sample I came up with is essentia...
Is it possible in W3C's XML Schema language (XSD) to allow a series of elements to be in any order but still limit occurrences?
I know about all and choice, but they don't account for a case where I do want some elements to be able to occur more than once, such as: <Root> <ThingA/> <ThingB/> <ThingC/> <ThingC/> <ThingC/> </Root> I could use sequence, but I'd prefer to allow these children to be in any order. I could use any, but then I coul...
What XML do I send for a field thats declared as nillable?
I have an application with a REST style inerface that takes XML documents via POST from clients. This application is written in Java and uses XML beans to process the posted message.

Validate an incoming SOAP request to the WSDL in PHP
The built-in PHP extension for SOAP doesn't validate everything in the incoming SOAP request against the XML Schema in the WSDL. It does check for the existence of basic entities, but when you have something complicated like simpleType restrictions the extension pretty much ignores their existence. What is the best way to validate the S...
Can you use key/keyref instead of restriction/enumeration in XML schema?
Suppose we have a stylesheet which pulls in metadata using the key() function. In other words we have instance documents like this: <items> <item type="some_type"/> <item type="another_type"/> </items> and a table of additional data we would like to associate with items during processing: <item-meta> <item type="some_type" meta=...

What are the advantages and disadvantages of using XML schemas?
We are utilizing the XML data type in Microsoft SQL Server 2005 for a project. Some members of the team and I feel that we should also use XSDs while members of the other camp feel that we should keep the XMLs ad hoc and not treat them as "types". The XMLs are an effort to bring structure and centrality to a number of text configuration...
Recursion in XSD Schemas
I need to create an XSD schema that validates a tree structure of an XML document. I don't know exactly the ocurrences or depth level of the tree.

What do you use for validation against XML schema?
When I want to validate my XML docuemnts against a schema in my server-side Java, I use the built-in JRE Xerces implementation and javax.xml.validation.Schema. It works fine, but when validation fails, Xerces gives error messages that are very close to useless, for example: cvc-minLength-valid: Value '' with length = '0' is not facet-v...
Validating and reparing xml
Is there a way to get more useful information on validation error? XmlSchemaException provides the line number and position of the error which makes little sense to me. Xml document after all is not about its transient textual representation. I'd like to get an enumerated error (or an error code) specifying what when wrong, node name (or...

I'm working in a project which needs to clean up some third party XSD Schemas and I want to do some refactoring of common elements in them. There is any suitable tool to automate this?

What are best practices for designing XML schemas?
As an amateur software developer (I'm still in academia) I've written a few schemas for XML documents. I routinely run into design flubs that cause ugly-looking XML documents because I'm not entirely certain what the semantics of XML exactly are. My assumptions: <property> value </property> property = value <property attribute="attv...
Guidelines for formatting XML Namespace
I have not developed web services applications that publicly faced the Internet. As I begin to consider the issues of exposing schema definitions to a wide audience, I believe a certain amount of consideration should be spent on properly formatting the schema namespaces. Has anybody come across a guideline document that advises how to g...
