查找一个

<div class="id1">
	<table>
		<thead>
			<tr>
				<th>company</th>
				<th>urls</th>
				<th>zipcode & city</th>
			</tr>
		</thead>
		<tbody>
			<tr>
				<td>Hegland GmbH</td>
				<td>
				    <ul>
				        <li>http://www.companylink1.ch</li>
				        <li>http://www.companylink2.ch</li>
				        <li>http://www.companylink3.ch</li>
                    </ul>
                </td>
				<td>8400 Winterthur</td>
			</tr>
		</tbody>		
	</table>
</div>
<ul>
<li>http://www.link1.ch</li>
<li>http://www.link2.ch</li>
<li>http://www.link3.ch</li>
</ul>
<div class="id2">
           ^^^^^^
	<table>
		<thead>
			<tr>
				<th>name</th>
				<th>street</th>
				<th>zipcode & city</th>
			</tr>
		</thead>
		<tbody>
		^^^^^^^
			<tr>
				<td>Roger Hegland</td>
				^^^^=============^^^^^
				<td>Châtelstrasse 13</td>
				<td>8355 Aadorf</td>
			</tr>
		</tbody>		
	</table>
</div>

在以下示例中，我们得到名字 "Roger Hegland"

$name = Parser::findOne($text, '"id2">', '<tbody>', '<td>', '</td>');

/*
result = (string) 'Roger Hegland'
*/

查找多个

请注意，第一个参数用于结束搜索。

在以下示例中，我们得到所有链接名称

<div class="id1">
	<table>
		<thead>
			<tr>
				<th>company</th>
				<th>urls</th>
				<th>zipcode & city</th>
			</tr>
		</thead>
		<tbody>
			<tr>
				<td>Hegland GmbH</td>
				<td>
				    <ul>
				        <li><a href="http://www.companylink1.ch">companylink1</a></li>
				        ^^^^                                   ^^============^^^^
				        <li><a href="http://www.companylink2.ch">companylink2</a></li>

                    </ul>
                </td>
				<td>8400 Winterthur</td>
			</tr>
		</tbody>		
	</table>
</div>
<ul>
<li><a href="http://www.link1.ch">link1</a></li>
^^^^                            ^^=====^^^^
<li><a href="http://www.link2.ch">link2</a></li>
^^^^                            ^^=====^^^^
<li><a href="http://www.link3.ch">link3</a></li>
^^^^                            ^^=====^^^^
</ul>
<div class="id2">
	<table>
		<thead>
			<tr>
				<th>name</th>
				<th>street</th>
				<th>zipcode & city</th>
			</tr>
		</thead>
		<tbody>
			<tr>
				<td>Roger Hegland</td>
				<td>Châtelstrasse 13</td>
				<td>8355 Aadorf</td>
			</tr>
		</tbody>		
	</table>
</div>

Parser::findMany($text, '</a>', '<li>', '">' );

/*
result = array
[
    'companylink1',
    'companylink2',
    'companylink3',
    'link1',
    'link2',
    'link3'
]
*/

如果您只需要在表格中链接名称，您可以这样做

<div class="id1">
	<table>
		<thead>
			<tr>
				<th>company</th>
				<th>urls</th>
				<th>zipcode & city</th>
			</tr>
		</thead>
		<tbody>
			<tr>
				<td>Hegland GmbH</td>
				<td>
				    <ul>
				        <li><a href="http://www.companylink1.ch">companylink1</a></li>
				        ^^^^                                   ^^============^^^^
				        <li><a href="http://www.companylink2.ch">companylink2</a></li>
				        ^^^^                                   ^^============^^^^
				        <li><a href="http://www.companylink3.ch">companylink3</a></li>
				        ^^^^                                   ^^============^^^^
                    </ul>
                </td>
				<td>8400 Winterthur</td>
			</tr>
		</tbody>
	</table>
</div>
<ul>
<li><a href="http://www.link1.ch">link1</a></li>
<li><a href="http://www.link2.ch">link2</a></li>

$text = Parser::findOne($text, '<tbody>', '</tbody>' );
Parser::findMany($text, '</a>', '<li>', '">' );
