QTP Working with XML

XML 是一种标记语言，设计用于将数据存储为人类和机器都可以读取的格式。使用 XML 还可以轻松地在计算机和数据库系统之间交换数据。

示例 XML 及其关键元素如下所示 −

Accessing XML

Const XMLDataFile = "C:\TestData.xml"
Set xmlDoc = CreateObject("Microsoft.XMLDOM")
xmlDoc.Async = False
xmlDoc.Load(XMLDataFile)

' Getting the number of Nodes (books)
Set nodes = xmlDoc.SelectNodes("/bookstore/book")
Print "Total books: " & nodes.Length    ' Displays 2

' get all titles
Set nodes = xmlDoc.SelectNodes("/Booklib/book/value/text()")

' get their values
For i = 0 To (nodes.Length - 1)
   Title = nodes(i).NodeValue
   Print "Title is" & (i + 1) & ": " & Title
Next

Comparing XML

我们可以比较给定的两个 XML −

Dim xmlDoc1
Dim xmlDoc2

' Load the XML Files
Set xmlDoc1 = XMLUtil.CreateXMLFromFile ("C:\File1.xml")
Set xmlDoc2 = XMLUtil.CreateXMLFromFile ("C:\File2.xml")

'Use the compare method of the XML to check if they are equivalent
Comp = xmlDoc1.Compare (xmlDoc1, xmlDoc2)

'Returns 1 if the two files are the same
If Comp = 1 Then
   Msgbox "XML Files are the Same"
Else
   Msgbox "XML Files are Different"
End if
