核心代码:
If WScript.Arguments.UnNamed.Count <> 1 Then Syntax
If WScript.Arguments.Named.Count > 1 Then Syntax
blnTd = False
If WScript.Arguments.Named.Count = 1 Then
If UCase( WScript.Arguments.Named( 0 ) ) = "/TD" Then
blnTd = True
Else
Syntax
End If
End If
strISBN = WScript.Arguments.UnNamed( 0 )
strPgTitle = TitleFromHTML( "http://www.amazon.com/gp/product/" & strISBN & "/" )
strPattern = "Amazon.com: (.*): Books: (.*)$"
strTitle = RegExpVal( strPattern, strPgTitle, 0 )
strAuthor = RegExpVal( strPattern, strPgTitle, 1 )
If blnTd Then
strMsg = strISBN & vbTab & strTitle & vbTab & strAuthor & vbCrLf
Else
strMsg = vbCrLf & "Title : " & strTitle _
& vbCrLf & "Author : " & strAuthor _
& vbCrLf & "ISBN : " & strISBN
End If
WScript.Echo strMsg
Function RegExpVal( strPattern, strString, idx )
On Error Resume Next
Dim regEx, Match, Matches, RetStr
Set regEx = New RegExp
regEx.Pattern = strPattern
regEx.IgnoreCase = True
regEx.Global = True

End Function
Function TitleFromHTML( strURL )
Set ie = CreateObject( "InternetExplorer.Application" )
ie.Navigate strURL
Do Until ie.ReadyState = 4
WScript.Sleep 10
Loop
TitleFromHTML = ie.Document.Title

End Function
Sub Syntax
strMsg = strMsg & vbCrLf & "BookFind.vbs, Version 1.11" & vbCrLf _

End Sub
使用方法:
CSCRIPT //NOLOGO BOOKFIND.VBS isbn [ /TD ]
Where: "isbn" is the ISBN (or ASIN) of the book to search for
/TD changes the output format to tab delimited
Note: This script uses Amazon's web site to look up author and title.
To be precise, the data is extracted from the title of the page
with URL http://www.amazon.com/gp/product/ followed by the ISBN.
That means this script will fail when Amazon changes the URLs.
