HI all,

Can any one help me to solve the problem of
solving this problem
listed below..

1)My requirement is to modify the XSD file by using
the XPath.
2)XPath will be in terms of the element name and
not it terms of element.

for Example

The XSD file will look like this

<xs:complexType name=" AuthorsType ">

<xs:attribute name="Name" type="xs:string" use="required"/>

</xs:complexType>

<xs:element name="BookType">
<xs:complexType >

<xs:sequence>

<xs:element ref="Name"/>

<xs:element name="Authors" type="AuthorsType"/>

<xs:element ref="ISBN"/>

<xs:element ref="Publisher"/>

<xs:element ref="Shelf"/>

</xs:sequence>

</xs:complexType>
</xs:element >
<xs:element name="BookStore">

<xs:complexType>

<xs:sequence>

<xs:element ref="BooksType"/>

<xs:element name="Novels" type="NovelsType"/>

<xs:element name="Magazines" type="MagazinesType"/>

</xs:sequence>

</xs:complexType>

</xs:element>

Xpath will be BookStore/BooksType/AuthorType/@name that means BookStore
contains Books of type BooksType and BooksType contains Authors of type
AuthorsType

In the AuthorsType I want to change this attribute of use to optional
<xs:attribute name="Name" type="xs:string" use="required"/>

Let me make an attempt in answering your query.
You could write a code that walks through the xsd model and puts your
xpath as key and the corresponding element / attribute as the object
inside a map object. I dont think there is anything available to do this
ready made.

Subsequently you could fetch the elemnt/attribute from the xpath.

Me and a friend have made something similar its not thoroughly tested (and
it does not work properly under certain scenarios such as when the com pex
type is extended by extension element)and we are interested only in read
access and not in modifying the xsd.
