启动 wget下载网站所有页面到本脚本目录的 720.hao2046.net 文件夹
WScript.Echo "1. 启动 wget下载网站所有页面到本脚本目录的 720.hao2046.net 文件夹 ……"
wso.Run "wget -r -p -k -c -x -A=jpg,htm,html 720.hao2046.net -P """ & strMeDir & """", 1, True
扫描 720.hao2046.net 文件夹中所有文件

建立正则表达式 。
Dim regEx
Set regEx = CreateObject("VBScript.RegExp") 建立正则表达式 。
regEx.IgnoreCase = True 设置是否区分大小写 。
regEx.Global = True 设置全局替换 。
regEx.MultiLine = True 设置多行匹配模式
查找所有文件
WScript.Echo "3. 读取 720.hao2046.net 文件夹中的所有网页，匹配图片 URL 地址 ……"
For i = 0 To UBound(arr)
If LCase(Right(arr(i),5)) = ".html" Or LCase(Right(arr(i),4)) = ".htm" Then
读取文件，匹配图片 URL 地址
strHTML = ReadPfile(arr(i), "gb2312")
regEx.Pattern = "src=[""]http://\S+\.jpg[""]"
Set Matches = regEx.Execute(strHTML) 执行搜索 。
For Each Match in Matches 遍历匹配集合 。
If Not Match.Value = "" Then
regEx.Pattern = "(src=[""])*([""])*"
strURL = strURL & regEx.Replace(Match.Value, "") & vbCrLf
End If
Next
End If
Next
保存所有图片 URL 地址
WScript.Echo "4. 保存所有图片 URL 地址到 url-img.txt 文件 ……"
Call SavePfile(strMeDir & "\url-img.txt", "utf-8", strURL)
启动 wget 下载图片到本脚本 img 目录
WScript.Echo "5. 启动 wget 下载 url-img.txt 指定的图片到本脚本 img 目录 ……"
wso.Run "wget -c -x -t 5 -i """ & strMeDir & "\url-img.txt"" -P """ & strMeDir & "\img""", 1, True
