How to get the root element in Moxy - jaxb

I am trying to create an xml by analyzing an xsd using Moxy. I will not be aware of how the xsd looks like.
The xsd will be provided on the fly. Using Moxy I am able to load the xsd and print details of all the XmlDescriptors. My question is, how to identify the root element.
Thanks

Having xsd, any global type can be root element of xml document. For such global type, use method
org.eclipse.persistence.oxm.XMLDescriptor#getDefaultRootElement
to get name of root element.

Generate XSD from Java WITH documentation

I created an XSD schema and have put in some documentation via the tag.
from the XSD i generated Java classes using Jaxb (from within eclipse - jdk1.6)
i now plan to use my java classes as "source" and modify them as per requirements that come up
I will generate XSD back from modified Java classes to keep the XSD in-sync.
in this process any "documentation" on the XSD gets lost. (i.e. when i generate it from Java). Is there some way to get around this? Thanks.

Jaxb XML binding file generator from annotations?

I am working on project in which we need get rid of all JAXB annotations for readability sake and write XML binding file only. Are there any XML binding file generator from Annotated JAXB classes to ease my task of writing binding XML ?
You can achieve this using MOXy (this is JAXB extension). Check more examples in Blaise Doughan blog: Extending JAXB - Representing Metadata as XML and Mapping Objects to Multiple XML Schemas - Weather Example.

XSD TO XML Conversion

I want to write a java program, Input - XSD File I need to retreive all the element name from the xsd and need to create an xml file as an output with the retreived element name. If anyone of you have the sample code, please share it.
Thanks
You are not rephrasing your question,but still i found some suggestions for you.See if its useful for you.Please check the following link...

Alright use JAXME or XSOM to parse your schema and use DOM or JDOM to write the element names to new xml
if you want to create a sample XML from schema ..you can use XMLspear tool to do that.

Load XML file into object. Best method?

We are receiving an XML file from our client. I want to load the data from this file into a class, but am unsure about which way to go about it.
I have an XSD to defining what is expected in the XML file, so therefore i can easily validate the XML file.
Can i use the XSD file to load the data into a POCO, using some sort of serialization?
The other way i was thinking was to load the xml into a XMLDocument and use XPath to populate each property in my class.
Cheers for any advice
Depending on how complex the XSD is, you have a couple of options:
Use xsd.exe to generate C# classes which can be used in conjunction with the XmlSerializer.
Use svcutil.exe with the /dconly argument to generate DataContract-attributed types appropriate for use with the DataContractSerializer.
