我有一個批處理文件,從管理門戶網站獲取圖像上傳目錄的內容,並生成一個文本文件,其中包含每個圖像的img src屬性。尋找批處理文件插入新行到文本文件

在這一點上,每個這些文本文件都包含20多個圖像的屬性,然後我通過c#代碼後面的文件將其拉入aspx頁面中的div。

我正在切換到新的佈局,所以我必須在每3行後添加</l> i>>。

我試圖找出如何使用批處理文件來讀取包含文本的IMG SRC的每3行之後插入代碼,但我完全lost.bat

現在 - 如果NJACPM。TXT包含

=============================== 
line of text 1 

line 3 - 2 was empty 
: and this behind colon 
but this doesn't 
A line of ] many <and>varied %poison^characters | like "," and so on 
another line 
and another 

now a real test %path% and !path! 
what say you now? 
=============================== 

,輸出是:

=============================== 
line of text 1 

line 3 - 2 was empty 
</li><li> 
: and this behind colon 
but this doesn't 
A line of ] many <and>varied %poison^characters | like "," and so on 
</li><li> 
another line

+ 1,不需要設置EMPTY和測試是否定義,只需用'echo(!line:*:=!'替換這兩行就可以了,因爲'echo.'可能會失敗,所以我使用'echo('而不是'echo.') 'echo('always works。 – dbenham 2013-04-07 13:33:02

它可以做很容易地用足使用FOR/F遍歷行的純批處理,SET/A遞增計數器,以及延遲擴展或CALL到子例程以及IF語句,以在每行第3行添加額外文本。

但我會用我已經寫過的一個實用程序來執行正則表達式搜索和替換。它是一個名爲REPL.BAT的混合JScript /批處理腳本,適用於任何現代Windows平臺。如果您知道正則表達式,使用起來非常簡單,而且比任何純粹的批處理解決方案快得多。

它有一個M(多行)選項,允許跨換行符進行搜索和替換,以及一個允許替換文本中使用轉義序列的X(擴展替換)選項。

假設REPL.BAT要麼在您的當前文件夾中,要麼在PATH中的某個位置,那麼以下簡單腳本會在原始文件的每一行之後插入</li><li>作爲新行。

編輯:parametized的「注入每一個」計數,並在替換字符串

@echo off 
setlocal 
set "file=test.txt" 
set "count=3" 
<"%file%" call repl "((.*\n){%count%})" "$1</li><li>\r\n" mx >"%file%.new" 
move /y "%file%.new" "%file%" >nul 

這裏改變\n\r\n是REPL.BAT文件,使上面的腳本工作。它內嵌了完整的文檔。

::: 
:::REPL Search Replace [Options [SourceVar]] 
:::REPL /? 
::: 
::: Performs a global search and replace operation on each line of input from 
::: stdin and prints the result to stdout. 
::: 
::: Each parameter may be optionally enclosed by double quotes. The double 
::: quotes are not considered part of the argument. The quotes are required 
::: if the parameter contains a batch token delimiter like space, tab, comma, 
::: semicolon. The quotes should also be used if the argument contains a 
::: batch special character like &, |, etc. so that the special character 
::: does not need to be escaped with ^. 
::: 
::: If called with a single argument of /? then prints help documentation 
::: to stdout. 
::: 
::: Search - By default this is a case sensitive JScript (ECMA) regular 
:::   expression expressed as a string. 
::: 
:::   JScript syntax documentation is available at 
:::   http://msdn.microsoft.com/en-us/library/ae5bf541(v=vs.80).aspx 
::: 
::: Replace - By default this is the string to be used as a replacement for 
:::   each found search expression. Full support is provided for 
:::   substituion patterns available to the JScript replace method. 
:::   A $ literal can be escaped as $$. An empty replacement string 
:::   must be represented as "". 
::: 
:::   Replace substitution pattern syntax is documented at 
:::   http://msdn.microsoft.com/en-US/library/efy6s3e6(v=vs.80).aspx 
::: 
::: Options - An optional string of characters used to alter the behavior 
:::   of REPL. The option characters are case insensitive, and may 
:::   appear in any order. 
::: 
:::   I - Makes the search case-insensitive. 
::: 
:::   L - The Search is treated as a string literal instead of a 
:::    regular expression. Also, all $ found in Replace are 
:::    treated as $ literals. 
::: 
:::   E - Search and Replace represent the name of environment 
:::    variables that contain the respective values. An undefined 
:::    variable is treated as an empty string. 
::: 
:::   M - Multi-line mode. The entire contents of stdin is read and 
:::    processed in one pass instead of line by line.^anchors 
:::    the beginning of a line and $ anchors the end of a line. 
::: 
:::   X - Enables extended substitution pattern syntax with support 
:::    for the following escape sequences: 
::: 
:::    \\  - Backslash 
:::    \b  - Backspace 
:::    \f  - Formfeed 
:::    \n  - Newline 
:::    \r  - Carriage Return 
:::    \t  - Horizontal Tab 
:::    \v  - Vertical Tab 
:::    \xnn - Ascii (Latin 1) character expressed as 2 hex digits 
:::    \unnnn - Unicode character expressed as 4 hex digits 
::: 
:::    Escape sequences are supported even when the L option is used. 
::: 
:::   S - The source is read from an environment variable instead of 
:::    from stdin. The name of the source environment variable is

這是可以做到容易地足以與通過管線使用FOR/F以循環純批次,SET/A遞增計數器,並且或者延遲擴展或CALL到子程序使用IF語句沿每隔三行增加額外的文本。

所以在這裏你會得到純淨的感覺一批:-)

@echo off 
setlocal 
set "file=test.txt" 
set /a counter=0 

(for /f "delims=" %%i in ('^<%file% findstr /n "^"') do call:processline "%%~i")>%file%.new 
goto:eof 

:processline 
set "line=%~1" 
set /a check=counter%%3 
if %check% equ 0 if %counter% neq 0 echo(^</li^>^<li^> 
set /a counter+=1 
setlocal enabledelayedexpansion 
echo(!line:*:=! 
endlocal 
exit /b
