将计划文本与 HTML 内容匹配

Question

我需要在植物文本与HTML内容之间进行匹配，一旦找到匹配，我需要提取匹配的HTML内容（不改变HTML内容因为我需要完全相同的HTML内容），我可以使用 java regex 实用程序在许多场景中进行匹配，但在以下场景中失败。

下面是我用来匹配文本和 HTML 字符串的示例代码

public static void main(String[] args) {

    String text = "A crusader for the rights of the weaker sections of the Association's (ADA's),choice as the presidential candidate is being seen as a political masterstroke.";
    String regex = "A crusader for the rights of the weaker sections of the Association's (ADA's) ".replaceAll(" ", ".*");

    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(text);
    // Check all occurrences
    while (matcher.find()) {

        System.out.print("Start index: " + matcher.start());
        System.out.print(" End index: " + matcher.end());
        System.out.println(" Found: " + matcher.group());

    }
}

在边缘情况下会失败

案例一：

原文： = "A crusader for the rights of the weaker sections of the Association's (ADA's),choice as the presidential candidate is being seen as a political masterstroke.";

要匹配的文本 = "A crusader for the rights of the weaker sections of the Association's (ADA's)"

预期输出： “A crusader for the rights of the weaker sections of the Association's (ADA's)”

案例 2：

原文：

“<ul>
   <li>Lorem ipsum dolor sit amet, consectetuer adipiscing elit.</li>
   <li>Aliquam tincidunt mauris eu risus.</li>
   <li>Vestibulum auctor dapibus neque.</li>
see (<a href=\"https://www.webpagefx.com/web-design/html-ipsum/">HTML Content Sample </a>.)
</ul>”

要匹配的文本： “see (HTML Content Sample.)”

预期输出： “see (<a href=\"https://www.webpagefx.com/web-design/html-ipsum/">HTML Content Sample </a>.)”

案例 3： 原文： = "Initial history includes the following:</p>\n<p>Documentation of <li>Aliquam tincidunt mauris eu risus.</li>"

要匹配的文本 = "Initial history includes the following: Documentation of"

匹配的预期输出：”Initial history includes the following :</p>\n<p>Documentation of”

我最近想出了一个匹配 HTML 标记的正则表达式，支持带引号的属性和带引号的属性中的转义引号：它类似于
<([^'">]|"([^\\"]|\\"?)+"|'([^\\']|\\'?)+')+>。

我认为在 HTML 中搜索纯文本同时保留 HTML 的最简单方法是修改纯文本，使其忽略单词边界处的标签，à la

// Usage: htmlSearch("ab cd").matcher("<b>ab</b> <i>cd</i>").matches();
public static Pattern htmlSearch(String plain) {
    // Check for tags before and after every word, number and symbol
    plain = plain.replaceAll("[A-Za-z]+|\\d+|[^\\w\\s]", 
            "``TAGS``$0``TAGS``";
    // Check for tags wherever (one or more) spaces are found
    plain = plain.replaceAll("\\s+", "((\\s|&nbsp;)+|``TAGS``)*");
    // Handle special characters
    plain = plain
            .replace("<", "(<|&lt;|&#60;)")
            .replace(">", "(>|&gt;|&#62;)")
            .replace("&", "(&|&amp;|&#38;)")
            .replace("'", "('|&apos;|&#39;)")
            .replace("\"", "(\"|&quot;|&#34;)")
            .replaceAll("[()\\\\{}\\[\\].*+]", "\\$0");
    // Insert the ``TAGS`` pattern
    String tags = "(<([^'\">]"
                + "|\"([^\\\"]|\\\"?)+"
                + "|'([^\\']|\\'?)+')+>)*";
    plain = plain.replace("``TAGS``", tags);

    return Pattern.compile(plain);
}
