如何搜索字符串并将其替换为变量。 我想搜索version =“1.37.0”,但版本号可能是任何东西。在package.xml中有两个“version =”字符串,但我想替换第二个。
如何搜索version =“x.x.x”并将其替换为version =“$ variable”? 有没有一个班轮?
我确实试图用这样的东西来搜索:
findstr "version="[0-9].[0-9].[0-9]" package.xml
对于desrciption也是同样的事情=“$ variable1”
package.xml中
<?xml version="1.0" encoding="utf-8"?>
<PackageManifest>
<Package name="audio"
description="something. . .."
version="1.37.0"
comment="">
</Package>
</PackageManifest>

试试这个:
@echo off
set $FindStr=Version="x.x.x"
set $ReplString=Version="y.y.y"
setlocal enabledelayedexpansion
for /f "delims=" %%a in ('type test.xml') do (
set $Ver=%%a
set $Ver=!$Ver: =!
If /i !$Ver!==%$FindStr% set $Ver=%$ReplString%
echo !$Ver! ) >> Output.xml
非常简单,但基础很好
修改:
这将询问第二个匹配的version=
@echo off
set "$FindStr=Version="
set $c=1
setlocal enabledelayedexpansion
for /f "delims=" %%a in ('type test.xml') do (
set $Ver=%%a
set $Ver=!$Ver: =!
If /i "!$Ver:~0,8!"=="%$FindStr%" (
if !$c! GTR 1 (
set /p "$NewVer=Enter New version : "
set $Ver=%$FindStr%!$NewVer!)
set /a $c+=1)
echo !$Ver! >> Output.xml)
输入文件为text.xml
,ouputFile为Output.xml
