linux awk中的转义HTML特殊字符

从awk脚本中，我想生成一个HTML文件。我的字符串可能包含像“<”和“&"这样的字符。有没有一个简短的、经过验证的awk函数来执行转义？

为了逃避最低限度，你可以这样做：

function escapeHtml(t)
{
  # Must do this one first
  gsub(/&/, "\\&amp;", t);
  gsub(/"/, "\\&quot;", t)
  gsub(/</, "\\&lt;", t);
  gsub(/>/, "\\&gt;", t);
  return t;
}

字符串

当然。只需为您想要转换的每一行调用makeEntities()（$0）。或者修改它以接受参数。我这样做是为了使用英国国家语料库，它与HTML实体有高度的重叠，但 * 不是100%*，所以如果您需要一些外来字符，您应该验证它们是否正确。

function makeEntities()  {    
    gsub(/á/,  "\\&aacute;");
    gsub(/Á/,  "\\&Aacute;");
    gsub(/ă/,  "\\&abreve;");
