标题: 如何截取内容？ [打印本页]
作者: oicq63236 时间: 2009-4-28 12:37 标题: 如何截取内容？
这是一个笑话网，我通过脚本自动下载，并想截取下列红色部分的内容到一个文件内，然后调用DOS版飞信向手机发送信息，现在取不出红色的内容．
红色的内容每条都不一样，但是蓝色部分是固定的，即两块蓝色区域中的内容．

也许一条简单的for命令就可以了 ,楼主试试看
for /f "tokens=* eol=<" %%i in (test.htm) do @echo.%%i>dest_text.txt作者: jmz573515 时间: 2009-4-29 02:50
vbs的
set fso=createobject("scripting.filesystemobject")
set file=fso.opentextfile("test.htm")
s=file.readall
file.close
Function getImages(Str)
Set re = New RegExp
re.global=true
re.Pattern = "\n\W+"""
Set Contents = re.Execute(Str)
For Each Match in Contents
Images = Images +Match+vbcrlf
Next
getImages =Images
End Function
set file=fso.createtextfile("#test.txt")
file.write getimages(s)
file.close
createobject("wscript.shell").run "#test.txt"

思路很好但有点问题，改正如下：
for /f "tokens=1 eol=<" %%i in (test.htm) do @echo.%%i>>dest_text.txt

楼上的发现有点问题，具体是什么问题，你能说说吗？我测试了是没发现问题，除了下面句中的红色部分被提取了外．不过你修改后的好象也没解决这个问题<img src="images/smilies/face-wink.png" align="absmiddle" border="0">
