如何找到不属于任何元素的值，在这种情况下，它们是GLUCK MARTIN，MEDICINE，077798,05 / 05/56等。

Answer 1

使用jQuery很容易 - 组合不包含：

$("#content_column").not(":contains('GLUCK MARTIN')")

Answer 2

请参阅this answer：

$('#content_column').clone().children().remove().end().text()

以下是带有示例标记的fiddle。

Answer 3

在节点中，我建议使用DOM而不是像regex这样的scrape工作。 jsdom是一个很好的，它允许您从片段中构建DOM。从那里，您可以查询document.documentElement（在我的示例中，我将使用jquery）并提取未包含在标记中的任何直接文本节点。

// Count all of the text not in a tag
var jsdom = require("jsdom");

jsdom.env(
  "URL OR YOUR HTML STRING HERE",
  ["http://code.jquery.com/jquery.js"],
  function (errors, window) {
    var textNodes = window.$(window.document.documentElement)
        .find(":not(iframe)")
        .addBack()
        .contents()
        .filter(function() {
            return this.nodeType == 3;
        });
    //do something with textNodes
  }
);

使用javascript查找那些不在任何元素内的文本
