For small data, the XML file has many advantages in Access in retrieval updates.
I have tested that there is no database, put the membership information, product data information, transaction information, and website custom information, and the running results are very normal. It feels more than the database, but there is no test. Not sure. (Http://stone.yesku.net)
Let's talk about the main ways to create, query, modify the XML operation.
'Creating a DOM object set objdom = server.createObject ("Microsoft.xmldom")
'Take XML Data' Method 1 Take the XML Data of XML File ObjDom.Load ("C: / Test.xml") 'Method 2 Take the data of XML data strings ObjDom.LoadXML ("

You can enjoy the XMLHTTP objects to implement the XMLHTTP objects to implement many features under ASP using XMLDOM objects.
