I am using the ReadXMLSchema method of system.data.dataset to read a schema into a dataset.
I have an XML file that I build up and wish to do a .Update against a database.
The dataset doesn't have a schema and takes the following form:
xml:
<?xml version="1.0" encoding="utf-8"?>
<DataSetEntities xmlns:ms="urn:schemas-microsoft-com:xslt" xmlns:guids="urn:schemas-microsoft-com:guids" xmlns="C:/DACXML/EntityAttribute.xsd">

<IsMappable>true</IsMappable>
<EntityMask>0</EntityMask>
<DataSourceId>a3a1a14e-51d9-44b4-b0da-b5b564b405b1</DataSourceId>
</Entity>

</DataSetEntities>
schema i load in:
<?xml version="1.0" standalone="yes"?>

I read the schema in first with a ReadXMLSchema, i then use
ReadXml(sr,XmlReadMode.IgnoreSchema); where sr is the XML file above (dataset)
The dataset never polutes and when i do a .GetXML() i only get <DataSetEntities />
and not the full XML file, is there a problem with the XML.
any ideas?
cheers
chris.
