Hi All,
I was trying to Generate a XML from DataTable and with the help of the XML i will query it by using XPATH. Everything was working fine but the XPATH was not working because the XML what i generated does not have any Attributes in the XMLNodes up to my knowledge XPATH or XQuery will work only on the XML or IEnumerable<xelement> only when it has attribute with it. so how can i create a Attribute for the XML.

Note:
The reason why i was usign XPATH or XQuery is i was handeling with large amount of data ( 100000+) so i have tried creating attributed using a Foreach. since i was taking more time basically it was not recommened. so any one can Advise me some other plan. some BULK Attribute Creating logic which will not slow down my process.

Please let me know if any one can't understand or any mistakes in my post. Thanks

Hi _AKA_KSN_, use this datatable.WriteXml(strDirectory, XmlWriteMode.WriteSchema); let me know if aything.

Hope Schema will add a tag with field type and some namespace kind of thing. it Won't add any attribute to the XmlElements.

FYI:

Summary from the XmlWriteMode.WriteSchema
// Summary:
// Writes the current contents of the System.Data.DataSet as XML data with the
// relational structure as inline XSD schema. If the System.Data.DataSet has
// only a schema with no data, only the inline schema is written. If the System.Data.DataSet
// does not have a current schema, nothing is written.
