在windows上跑case时，我用它来替换xml文档中的名称和值什么的，还可以。但如果遇到bat中有特殊意义的字符比如<,>,%等就不行了，而且替换过程会消除每行的空格。鉴于dos知识有限，还没找到好的办法来避免这两种状况。如果用shell脚本完成替换功能就简单多了。或者直接用ultraedit的替换功能更简单。
代码如下：
@echo off rem *************************************************************************** rem ** replaceChar.bat - command line arguments List ** rem ** ** rem ** %1 - ext_name ** rem ** %2 - characters replaced ** rem ** %3 - new characters ** rem ** ** rem *************************************************************************** set ext_name=%1 set old_char=%2 set new_char=%3 if "%ext_name%" == "" goto warning if "%old_char%" == "" goto warning if "%new_char%" == "" goto warning setlocal enabledelayedexpansion set /a a=1 for %%x in (*.%ext_name%) do ( for /f "tokens=*" %%i in (%%x) do ( set "var=%%i" if not !var!.==. ( set "var=!var:%old_char%=%new_char%!" echo !var!!>>!a!.xml ) ) set /a a=!a!+1 ) goto end :warning echo the tool replaceChar requires 3 command line arguments: echo 1) ext name of file in which you want to replace some characters echo 2) characters you want to be replaced echo 3) new characters with which you want to replace some characeters :end echo ***** end to replace characters ***** echo -
如果想修改后的文件名和原来的一样，可以把这一段“echo !var!!>>!a!.xml
”改成“echo !var!!>>[path]%%x.xml
”，其中[path]是你的磁盘路径。
