Не работает регулярное выражение по выборке HTML <table>

Рейтинг: 0Ответов: 1Опубликовано: 15.02.2023

Есть такое регуляроное выражение для извлечения всего тега ( включительно ):

Regex tableLookupPattern = new Regex("<table class=\"table\" style=\"table-layout:fixed; \">(.*)</table>");

Но оно работает только для первой таблицы, потом в него попадают ненужные символы. Как это можно исправить?

HTML:

<body>
      <div class="main-content">
        <main id="ID0EH">
          <header>
            <nav>
              <ul>
                <li>
                  <a title="1. Untitled Chapter">1. Untitled Chapter</a>
                </li>
              </ul>
            </nav>
            <img style="height:7mm" alt="logo" src="" />
          </header>

Так что не работает с примером из комментария?

<table class=""table"" style=""table-layout:fixed; "">(.*?)</table>

Мне кажется это ваш искомый вариант - https://regex101.com/r/JYQQb0/1
