Add expected elements to xml

[webloem]

Hi all,

I am building an application in which users can edit data that is
stored as xml. I have a xmlfile with my data and a xsd file to validate
this data.

Sometimes i add elements to my xsd, without adding them to my data. Now
i want to build a function in my application that validates the data
using the xsd, and if an error occurs that it expects certain element
'x', adds this expected element to my data.

For example:

MyData.xml
<books>
<book>
<title>book2</book>
<name>Name2</name
<author>Author2</author>
</book>
<book>
<title>Title1</book>
<name>Name1</name>
</book>
</books>

part of MyXSD.xsd
<xs:element name="book">
<xs:complexType>
<xs:all>
<xs:element name="author" type="xs:string" />
<xs:element name="title" type="xs:string" />
<xs:element name="name" type="xs:string" />
</xs:all>
</xs:complexType>
</xs:element>

I want my program to add an element 'Author' to the book myData.xml,
containing the default value.

How can i do this, or what should i use? I am going to use this to add
new 'book' elements to my data that also include empty elements for all
the possible data fields.

This task is rather complex in general with all the possibilities and
combination of possibilities an XSD schema allows.
For .NET 2.0 there is an article on MSDN that shows how to generate a
sample XML document from a schema:

That should be a good starting point.
