简单的 HTML DOM 空格变成 class
Simple HTML DOM spaces into class
我正在使用 Simple HTML DOM 从网站获取元素，但是当 class 属性有空格时，我什么也得不到。

Class-名字没有空格，不要尝试匹配
SimpleHtmlDom 不支持这样的属性选择器。另外，您尝试匹配 class 就好像它在 class 名称中有空格一样。所以，而不是这个：
$wins = $html->find("td[class=wins col_wins]");
$draws = $html->find("td[class=draws col_draws]");
$losses = $html->find("td[class=losses col_losses]");
执行以下操作以匹配同时匹配两个 class 名称的 td 元素：
$wins = $html->find("td.wins.col_wins");
$draws = $html->find("td.draws.col_draws");
$losses = $html->find("td.losses.col_losses");
此外，HTML 标记不要求您匹配两个 class 来获取数据，您可以简单地执行以下操作：
$wins = $html->find("td.col_wins");
$draws = $html->find("td.col_draws");
$losses = $html->find("td.col_losses");
获取重复的选择器（遍历行）。
您要提取的是 table 行中的数据数组。更具体地说，看起来像这样：
$teams = [
['Arsenal', matches, wins, ...],
['Liverpool', matches, wins, ...],
...
];
这意味着您需要 运行 对 table 的每一行进行相同的数据提取。 SimpleHtmlDom 通过 jQuery-like find 方法使这变得容易，可以从任何匹配的元素调用这些方法。
完整的解决方案
这个解决方案实际上定义了一个 Team 对象来加载每一行的数据。应该使未来的调整更简单。
这里要注意的重要一点是，首先我们循环遍历每个 table 行作为 $row，并从 $row->find([selector]).[=20= 收集球队和号码]
// START team.php
class Team
{
public $name, $matches, $wins, $draws, $losses, $goals;
public function __construct($row)
{
$this->name = $this->parseMatch($row, 'span.team_name_span a');
if (null === $this->name) {
return; // couldn't even match the name, probably not a team row, skip it
}
$this->matches = $this->parseMatch($row, 'td.col_matches_played');
$this->wins = $this->parseMatch($row, 'td.col_wins');
$this->draws = $this->parseMatch($row, 'td.col_draws');
$this->losses = $this->parseMatch($row, 'td.col_losses');
$this->goals = $this->parseMatch($row, 'td.col_goals');
}
private function parseMatch($row, $selector)
{
if (!empty($match = $row->find($selector, 0))) {
return $match->innertext;
}
return null;
}
public function isValid()
{
return null !== $this->name;
}
public function getMatchData() //example

return "<br><b>". $this->wins .' : '. $this->matches . "</b>";
}
}
// END team.php
// START DOM parsing block
$teams = [];
foreach($html->find('table.stats-table tr') as $row) {
$team = new Team($row); // load the row into a Team object if possible
