typelib MSXML2 {F5078F18-C551-11D3-89B9-0000F81FE221} 4.0

MSXML2.XMLHTTP a._create
str xml =
;<?xml version="1.0" encoding="utf-8"?>
;<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
;;<soap:Body>
;;;;<Translate xmlns="http://www.webservicex.net">
;;;;;;<LanguageMode>EnglishTOGerman</LanguageMode>
;;;;;;<Text>string</Text>
;;;;</Translate>
;;</soap:Body>
;</soap:Envelope>

a.open("Post","http://www.webservicex.net/Translate/TranslateService.asmx",0)
a.setRequestHeader("Content-Type","text/xml")
a.send(xml)

MSXML2.FreeThreadedDOMDocument b._create
b.async
str r = a.responseXML = "xml"
;out b.loadXML(r)
out a.responseXML

using webservices would be very helpful:
Google Web APIs - Home
