vbscript xml問題

Question

我有這個調用.net 2010編寫的web服務的vbscript。 我在最後一行發生錯誤。無法弄清楚。 這是Web服務： http://www.kollelbaaleibatim.com/services/getinfo.asmx/GetFronpageInfo

Dim xmlDOC 
    Dim bOK 
    Dim J 
    Dim HTTP 
    Dim ImagePathLeftCar, ImagePathRightCar 
    Dim CarIDLeft, CarIDRight 
    Dim ShortTitleLeftCar, ShortTitleRightCar 
    Dim DescriptionLeftCar, DescriptionRightCar 
    Dim PriceLeftCar, PriceRightCar 

    Set HTTP = CreateObject("MSXML2.XMLHTTP") 
    Set xmlDOC =CreateObject("MSXML.DOMDocument") 
    xmlDOC.Async=False 

    HTTP.Open "GET","http://www.kollelbaaleibatim.com/services/getinfo.asmx/GetFronpageInfo", false 
    HTTP.setRequestHeader "Content-Type", "application/x-www-form-urlencoded" 
    HTTP.Send() 

    dim xmldoc2 
    set xmldoc2 = Server.CreateObject("Microsoft.XMLDOM") 
    xmldoc2.async = False 
    bOK = xmldoc2.load(HTTP.responseXML) 

    if Not bOK then 
     response.write("Error loading XML from HTTP") 
    end if 

    response.write(xmldoc2.documentElement.xml)'Prints a good looking xml 
     ShortTitleLeftCar = xmldoc2.documentElement.selectSingleNode("LeftCarShortTitle").text 'ERROR HERE 

Answer 1

這不是一個VBScript的問題，它是一個XPath問題。 xmldoc2.documentElement.selectSingleNode("LeftCarShortTitle")將嘗試找到「LeftCarShortTitle」元素作爲根的孩子....在你的情況下，因爲在此之前有各種級別，即<string><Root><FrontpageData>，所以你的情況將不起作用。

更新您的XPath是：

//LeftCarShortTitle

這將遍歷文檔的後代，應該找到你要找的節點。
