   RE: [xml-dev] Help for finding root node from XML Schema

[ Lists Home | Date Index | Thread Index ]

Title: Message
It's not just the root node that you can't determine -- an XML Schema defines a potentially infinite class of documents, and in the general case is not generative.
XForms solves this problem by asking the author to provide a prototype instance giving initial structure.
By the way, you might be interested in XForms, as it also performs display and allows structured editing of XML instances. See http://www.w3.org/MarkUp/Forms for a list of implementations.
There are some IE plugins, a Macromedia-flash zero-install version, an open source browser, and a few server-side transformation engines.

Subject: [xml-dev] Help for finding root node from XML Schema

Hello all,
I am new to XML and XML Schema. I am working on a project which involves visual display of XML Schema. For parsing  XML Schema I am using MSXML 4.0
My problem is How to get element  which will become root element of XML document which uses this schema.
 <xsd:element name="purchaseOrder" type="PurchaseOrderType" />
 <xsd:element name="comment" type="xsd:string"/>
 <xsd:complexType name="PurchaseOrderType">
  <xsd:sequence> ...
  <xsd:attribute name="orderDate" type="xsd:date"/>
When I parse above schema first call to get_childs returns two childs 1 ) comment 2) purchaseOrder.
So how to determine which is root?
Thanks & Regards,
 Priti Patil
