我编写了一个名为 REPL.BAT 的混合 JScript/批处理实用程序，可以帮助解决这个问题。我相信它会比任何纯批处理解决方案都要快得多。另一个不错的功能是这个解决方案可以很容易地适应进行正则表达式搜索和替换，而不是字符串文字搜索和替换。
假设我的 REPL.BAT 和您的 conf.txt 与您的 html 文件位于同一文件夹中，那么以下脚本应该可以工作：
@echo off
setlocal disableDelayedExpansion
:: Define LF to contain a newline (0x0A) character
set LF=^
:: The 2 blank lines above are critical - DO NOT REMOVE
:: Read the search and replace strings and store them in an "array"
:: Also, create a variable containing a cascading set of piped commands to
:: carry out each search and replace
:: Normally the search is in the s array, and the replacement in the r array.
:: But if the replacement is an empty string, then the search is in the r array
:: and the s array value is undefined.
set "cnt=0"
set "update="
for /f delims^=^ eol^= %%A in (conf.txt) do (
set "ln=%%A"
set /a cnt+=1
setlocal enableDelayedExpansion
for %%n in ("!LF!") do set "ln=!ln::::=%%~n!"
for %%N in (!cnt!) do (
for /f delims^=^ eol^= %%U in (""!update!"") do (
for /f delims^=^ eol^= %%L in ("!ln!") do (
if "!"=="" endlocal
if not defined r%%N (
set "r%%N=%%L"
) else (
set "s%%N=%%L"
)
)
if "!"=="" endlocal
if defined s%%N (
set "update=%%~U|repl s%%N r%%N vl"
) else if defined r%%N (
set "update=%%~U|repl r%%N "" vl"
)
)
)
)
:: Process each file
for %%F in (*.html) do (
echo processing %%F
type "%%F" %update% >"%%F.new"
move /y "%%F.new" "%%F" >nul
)
echo Done!
该脚本构建了一个搜索和替换字符串的“数组”：s1,s2,...sn和r1,r2,...rn
它还构建了一个update看起来像的命令
|repl s1 r1 vl|repl s2 r2 vl...|repl sn rn vl
每个文件都通过一组管道 REPL 命令传递，这些命令执行搜索和替换，每个 REPL 命令一个。
上面的脚本有以下限制：
- 我构建的最终
update命令的长度必须小于 8191 个字符，因此一次可以执行的搜索和替换操作的数量是有限的。理论上的限制是大约 480 次替换，但我不知道 Windows 在一个命令中处理这么多管道时会如何表现。
- 任何搜索或替换字符串都不能包含
:::. 这是 conf.txt 文件设计所固有的
这是上述脚本所需的 REPL.BAT 文件。完整的文档嵌入在脚本中。上面的脚本使用V从变量中读取搜索和替换字符串的L选项，以及强制进行文字搜索而不是正则表达式搜索的选项。

::************ Documentation ***********
:::
:::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 regex 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.
:::
::: B - The Search must match the beginning of a line.
::: Mostly used with literal searches.
:::
::: E - The Search must match the end of a line.
::: Mostly used with literal searches.
:::
::: V - 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
::: specified in the next argument after the option string.
