Question

基本上，我正在抓取包含&和>等实体的源代码，我希望将其替换为＆amp;和＆gt;分别。简单的字符串替换将是完全详尽的，因为有数百个可能的实体可以显示在源代码中。是否有内置或标准的方法，所以我不必键入一百行的字符串替换？

谢谢！：）

也许WebUtility.HtmlDecode方法就是你要找的东西

本文给出了一个使用Powershell来调用它的例子

# Create string to encode/decode
$Str = "<this is a string123> & so is this one??"

# Encode String
$Encstr = [System.Net.WebUtility]::HtmlEncode($str)

# Decode String
$Decstr = [System.Net.WebUtility]::HtmlDecode($EncStr)

# Display strings
"Original String: {0}" -f $Str
"Encoded String : {0}" -f $Encstr
"Decoded String : {0}" -f $Decstr
$eq = ($str -eq $Decstr)
"Original string = Decoded string?: {0}" -f $eq

我会使用sed控制台命令并为此创建一个小脚本。尝试谷歌sed 1行。我打赌你喜欢它。
