令牌和delims专家需要的帮助 [英] tokens and delims expert help needed
问题描述
最近，我在工作中经常使用批处理，以达到最佳效果，并且在这里和那里也使用了很少的电源外壳，从而产生了很大的效果.
I have been using batch a lot lately to great ends in my work and also little bits of power shell here and there to great effect.
一遍让我感到困惑的事情是通过循环等工作时的记号和delims概念.我已经看过您观看视频并阅读经典的rob van页面.我有点理解，但是当我需要使用它时，这不是基本的.
One thing that always baffles me is the tokens and delims concepts when working through loop etc. I have watched you tube videos and read the classic rob van pages on it. I kind of get it, but when I need to use it's not basic.
我举了一个例子，如果有人能很好地解释您如何选择代币和delims的数量，那将非常有帮助.我需要从网页的各个列中推断PC主机名.我可以将文本复制到文本板中，并想将计算机名称仅回显"到另一个文件中.
I have an example cropped up where if some one was kind enough to explain how you choose the number of tokens and delims it would be really helpful. I need to extrapolate a PC host-name from various columns in a web page. I can copy the text into a text pad and would like to "echo out" into another file just the computer names.

计算机名称是 ID0006962 数字，但我不需要结尾的 .CENTRAL .从此文本中，我只需要另一个带有主机名的文本文件.我可以做所有这部分，只是推断数据元素.有时列表很大，只需要保存到文本文件中，然后对它运行for循环，然后吐出另一个仅包含主机名的文本文件就可以了.我认为，如果我能对此有所了解，可以将知识应用到我也需要做的其他事情上.非常感谢您的提示！
The computer names are the ID0006962 numbers BUT I dont need the trailing .CENTRAL. From this text I just need another text file with the hostnames. I can do all that part, it's just the extrapolating data elements. Sometimes the lists are massive and it would be nice just save into a text file run a for loop against it and spit out a another text file with just the host-names. I think If I can get my head round this a little more I could apply the knowledge to other things I need to do as well. Many thanks for any tips !
在另一个文本文件中的示例输出(我想要):-
sample output (i'd like) in another text file:-
ID006967
ID007566
ID007567
ID006976
ID007643
编辑如何在主机名旁边获取3.10.6.0等
ID006967 3.10.6.0
ID007566 3.10.6.0
ID007567 3.10.6.0
ID006976 3.10.6.0
ID007643 3.10.6.0
我已经走了，但是迷路了，这就是我的想法...
I've had a go but got lost here's what I thought...
@echo off
> "%~dp0test.txt" (
for /F "usebackq tokens=4,5 delims= " %%J in ("%~dp0rob.txt") do @(
for /F "tokens=1,3,4,5,6 delims=." %%I in ("%%J") do @echo(%%I
)
)
所以我的想法(LOL)...我希望将4,5个令牌(第4和5列)提取到%% JI中，希望下一个循环回显其他令牌以及主机名，因此仍使用' ."作为该测试中第4行和第5行的定界符，我相信现在有6个标记可供选择....但是输出仍然只显示主机名...我不知道
so my thinking (LOL)...I want the 4,5 tokens (columns 4 and 5) extracting into %%J I want the next loop to echo the additional tokens as well as the host name, so still using '.' as a delimiter in this test with rows 4 and 5 I believe there are now 6 tokens to choose from....but the out put still just show the host name...what don't I get
ID006962(t1).CENTRAL(t2)3(t3).10(t4).6(t5).0(t6)
ID006962(t1).CENTRAL(t2) 3(t3).10(t4).6(t5).0(t6)
推荐答案
为您提供两种可能的解决方案.
Two possible solutions for you.
第一个使用与aschipfl的答案相同的思想，只是稍微精致一些，请记住delims = TAB :
The first uses the same idea as aschipfl's answer just slightly more refined, remember delims=TAB:
@(For /f "UseBackQTokens=4Delims= " %%A In ("pagedata.txt"
) Do @Echo=%%~nA)>another.txt
第二个将句点用作定界符:
The second uses the period as a delimiter:
@(For /f "UseBackQTokens=4Delims=." %%A In ("pagedata.txt"
) Do @For %%B In (%%A.x) Do @If Not "%%~xB"=="" Echo=%%~nB)>another.txt
只需更改pagedata.txt的输入文件名和another.txt的输出文件名即可.
Just change the input filename of pagedata.txt and the ouptput filename of another.txt to suit your purposes.
