[英]Escape double quotes in -replace
I have a PowerShell script to replace DEV web config entries with QA values. 我有一个PowerShell脚本,可以用QA值替换DEV Web配置条目。
So far good, but now I have some values with double quotes: 到目前为止还不错,但是现在我有一些带有双引号的值:
(Get-Content $targetFile) |
Foreach-Object {
$_ -replace "<add key="Path" value="/DEV/Reports" />", "<add key="WebReportsPath" value="/QA/Reports" />" `
-replace "<add key="EmpReport" value="/DEV/Emp/Reports" />", "<add key="EmpReport" value="/QA/Emp/Reports" />" `
-replace "olddatabase", "newdatabase"
} |
Set-Content $targetFile
I get parser error when I run. 运行时出现解析器错误。 If I change double quote to single quote like
如果我将双引号更改为单引号,例如
`-replace 'valwithdoublequote' 'valwithdoublequote' still I get parser error. How to escape this?
Since -replace
is using regex, you should use [regex]::Escape
to escape your characters (or use $_.Replace()
instead): 由于
-replace
使用正则表达式,因此应使用[regex]::Escape
来转义字符(或使用$_.Replace()
代替):
(Get-Content $targetFile) |
Foreach-Object {
$_ -replace [regex]::Escape('<add key="Path" value="/DEV/Reports" />'), '<add key="WebReportsPath" value="/QA/Reports" />' `
-replace [regex]::Escape('<add key="EmpReport" value="/DEV/Emp/Reports" />'), '<add key="EmpReport" value="/QA/Emp/Reports" />' `
-replace "olddatabase", "newdatabase"
} |
