直到我在 stackoverflow 上发现我应该替换所有的<with&lt;和所有的>with之前，Google Prettify 并没有为我正确显示 HTML &gt;。

这真的有必要吗？有没有更简单的方法来实现这一点？

我想显示如下简单代码：

<h1>Header</h1>

<p>This is a paragraph tag. Here is a <a href="#">LINK</a></p>

我可以使用什么东西来检测标签之间的所有<pre>代码吗？例如，当我在 stackoverflow 中输入代码时，我不需要替换<and >。

您可以使用 PHP 创建一个表单来获取输入的 HTML 并使用 PHP 函数 htmlentities() 替换 HTML 标记，或者您可以使用我偶然发现的这个 URL 为您寻找解决方案。http://www.boallen.com/htmlentities.html您输入您的代码，它会输出您的代码并应用 htmlentities。

不确定您对 PHP 的了解是什么，但您可以在此处阅读该函数的工作原理：http: //us3.php.net/manual/en/function.htmlentities.php

谷歌需要它。您可以使用预处理器语言（例如 php）来替换必要的字符。我相信你也可以在 javascript 中做到这一点。

但是，如果有帮助，这是一个规范化 HTML 字符串的本地 js 解决方案：

// HTML escape code repurposed from http://www.htmlescape.net/htmlescape_tool.html
function htmlEscapeString(unescaped_str)
{
  var escaped="";

  for(i=0; i<unescaped_str.length; i++)
  {
    escaped += escapeBR(escapeTags(escapeCharx(unescaped_str.charAt(i))));
  }

  return escaped;
}

function escapeBR(original)
{
  var thechar=original.charCodeAt(0);

  switch(thechar) {
    case 10: return "";
    case '\r': return ""; 
  }
  return original;  
}

function escapeNBSP(original)
{
  var thechar=original.charCodeAt(0);
  switch(thechar) {
    case 32: return "&nbsp;";
  }
  return original;  
}

function escapeTags(original)
{
  var thechar=original.charCodeAt(0);
  switch(thechar) {
    case 60:return "&lt;";  //<
    case 62:return "&gt;";  //>
    case 34:return "&quot;"; //"
  }
  return original;
}

function escapeCharx(original)
{
  var c = original.charCodeAt(0);
  switch(c) {
    case 38:return "&amp;";
    case 198:return "&AElig;";
    case 193:return "&Aacute;";
    case 194:return "&Acirc;";
