Ann: XMLDBelt v.1.0, server addition to handle content management via xml data files

[Guest]

XMLDB lite engine for accessing XML data files via HTTP. Engine allows you
to request data from xml file with using XPath. Imagine you have a set of
XML files with your content data and can be queried via HTTP, just by
sending GET/POST request to your server. XMLDBelt gets your request, process
it and returns only the chunk of data that you requested. Less traffic, less
time spent to process arrived data on your end. So, on your script side you
have less amount data to parse, means saving on performance too. Please not
that its not kinda real XMLDB to handle your content data files with size
about 100-700Mb, XMLDBelt made to handle less amounts of data.

For more details please visit http://www.webatarim.com/downloads/xmldbelt/

Sample ASP/VBScript to query remote XMLDBelt server:

<%
Response.Status = 200
Response.Clear

Dim HTTP
Set HTTP = Server.CreateObject("Msxml2.XMLHTTP.4.0")

dim xmlCmd
'- select
'xmlCmd = "<edxm><query><select from='myxmldocument.xml
with='//events'/></query></edxm>"

'- setproperty
'xmlCmd = "<edxm><query><setproperty key='user
value='admin'/></query></edxm>"

'- getproperty
'xmlCmd = "<edxm><query><getpropert
key='repository'/></query></edxm>"

xmlCmd = "<edxm><query><creat
file='%repository%events.xml'/></query></edxm>"

HTTP.open "POST", "http://localhost/xmldb/index.aspx", false
HTTP.send (xmlCmd)

Dim httpResponse

If http.status <> 200 Then
Response.ContentType = "text/html"
httpResponse = "HTTP Error #" & Http.status
Else
Response.ContentType = "text/xml"
httpResponse = HTTP.responseText
