powershell替换具有特殊字符的字符串不起作用

Question

$strText = '<httpHandlers>
      <remove verb="GET,HEAD,POST" path="*" />
    other content ....
        </httpHandlers>

$Pattern = '<remove verb="GET,HEAD,POST" path="*" />'
$New ='<remove verb="GET,HEAD,POST" path="*" NEW CONTENT ADDED />'
$strReplace = [regex]::replace($strText, $pattern, $New)`  

似乎不起作用

Answer 1

$strText = '<httpHandlers>
      <remove verb="GET,HEAD,POST" path="*" />
    other content ....
        </httpHandlers>'

$Pattern = [regex]::escape('<remove verb="GET,HEAD,POST" path="*" />')
$New ='<remove verb="GET,HEAD,POST" path="*" NEW CONTENT ADDED />'
$strReplace = [regex]::replace($strText, $pattern, $New)
$strReplace

1. 您的字符串$strText缺少报价
2. 您的图案包含特殊字符。使用静态方法[regex]::escape来解释它。
3. 不是真正的问题，但你有一个似乎不合适的尾随反复。
