可能重复：
正则表达式匹配打开的标签，XHTML 自包含标签除外

如何匹配HTML 标记之外的一些字母数字单词，而不是匹配每个单词

例子：

<div id="mariano mariano mariano" nota="mariano/mariano">mariano was looking forward Mariano. I want to match this "Mariano" too. Mariano</div>

在此示例中，我想匹配标签 ID 之外的所有“Mariano”。

我认为这个问题的关键是在“<”之前期待“<”并匹配该单词，但如果正则表达式在“<”之前找到“>”，这意味着该单词在标签中，但我无法为此实现/生成正则表达式。

我无法尝试将此正则表达式(?<=^|>)[^><]+?(?=<|$)与另一个正则表达式连接起来。我最终的最低质量解决方案是：

<!-- language: lang-js -->
var searchFor = new RegExp("((!?<=^|>)" + termino + ")","ig");
var searchFor2 = new RegExp("(" + termino + "(?=<|$))","ig");
var searchFor3 = new RegExp("(!?<=^|[\\s\\.;,])" + termino + "(?=[\\s\\.;,]|$)","ig");

但是这 3 个并没有涵盖所有的选择。

编辑：我正在使用 javascript：

<script>
container.find("p, span, div, .texto,").each(function() {
var containerText = $(this).html();
for (var i = 0; i < terms.length; i++) {
    var termino = terms[i];
    // 1st issue ">termino" was remplaced for: ">Pedro"
    var searchFor = new RegExp("((!?<=^|>)" + termino + ")","ig");
    containerText = containerText.replace(searchFor,">Pedroedro");
    // 2nd issue "termino<" was remplaced for: "Pedro"
    var searchFor2 = new RegExp("(" + termino + "(?=<|$))","ig");
    containerText = containerText.replace(searchFor2,"Pedro");
    // 3rd issue "[\.\s,;:]termino[\.\s,;:]
    var searchFor3 = new RegExp("(!?<=^|[\\s\\.;,])" + termino + "(?=[\\s        \\.;,]|$)","ig");
    containerText = containerText.replace(searchFor3," Pedro");
};
$(this).html(containerText);
}); 
</script>

一些东西 -

  1. 欢迎来到堆栈溢出！
  2. 请在提问前搜索问题。使用正则表达式解析 xml 有很多结果。

  3. 不要使用正则表达式来解析 xml/html！ 试试 xpath！

    var termino = // how ever you were defining before...

// Give me all divs, where the text content contains value of "termino"
var iterator = document.evaluate('//div/text()[contains(.,' + termino + ')]', documentNode, null, XPathResult.UNORDERED_NODE_ITERATOR_TYPE, null );

try {
  // init thisNode to the first item in the iterator
  var thisNode = iterator.iterateNext();

  // go through all items, alert their content (which should contain termino)
  while (thisNode) {
    alert( thisNode.textContent );
    thisNode = iterator.iterateNext();
  } 
}
catch (e) {
   dump( 'Error: Document tree modified during iteration ' + e );
}
