如何使用 php 解析 << 标签内的名称和<图像 src= - How to parse <a name and <image src= inside <li tag using php?

我得到了一个包含大量<li> .. </li>集的html字符串。我想解析每组<li> ...</li>的以下数据：

   1: call.php?category=fruits&amp;fruitid=123456
   2: mango season
   3: http://imagehosting.com/images/fru_123456.png

我用preg_match_all来获取第一个值，但是如何获取第二个和第三个值？如果有人告诉我得到第二和第三项，我会很高兴.提前谢谢。

.php：

preg_match_all('/getit(.*?)detailFruit/', $code2, $match);
var_dump($match);
  // iterate the new array
  for($i = 0; $i < count($match[0]); $i++)
{
$code3=str_replace('getit(''', '', $match[0]);
$code4=str_replace('&amp;'',detailFruit', '', $code3);
echo "<br>".$code4[$i];
}

示例<li> ..</li>数据：

<li><a id="FR123456" onclick="setFood(false);setSeasonFruitID('123456');getit('call.php?category=fruits&amp;fruitid=123456&amp;',detailFruit,false);">mango season</a><img src="http://imagehosting.com/images/fru_123456.png">
            </li>

编辑：我现在使用了 DOM，我得到了 2 和 3 个值，如何使用 DOM 获取第一个值？

libxml_use_internal_errors(true);
$dom = new DOMDocument;
$dom->loadHTML($code2);
$xpath = new DOMXPath($dom);
// Empty array to hold all links to return
$result = array();
//Loop through each <li> tag in the dom
foreach($dom->getElementsByTagName('li') as $li) {
    //Loop through each <a> tag within the li, then extract the node value
    foreach($li->getElementsByTagName('a') as $links){
        $result[] = $links->nodeValue;
        echo $result[0] . "'n";
    }
    $imgs = $xpath->query("//li/img/@src");
foreach ($imgs as $img) {
    echo $img->nodeValue . "'n";
}
}

有趣的问题：-）以下解决方案使用DOMDocument/SimpleXML的组合来轻松获取值 2 和 3。 DomDocument 被用作您的 HTML 代码段已损坏。为了从 JavaScript 内容中实际获取您的链接（值 1），使用了一个简单的正则表达式：

~getit'('([^']+)'')~
# search for getit( and a singlequote literally
# capture everything up to (but not including) a new single quote
# this is saved in the group 1

完整的演练可以在下面找到（显然我编造了banana部分）：

<?php
$html = '<ul>
<li><a id="FR123456" onclick="setFood(false);setSeasonFruitID(''123456'');getit(''call.php?category=fruits&amp;fruitid=123456&amp;'',detailFruit,false);">mango season</a><img src="http://imagehosting.com/images/fru_123456.png"></li>
<li><a id="FR7890" onclick="setFood(false);setSeasonFruitID(''7890'');getit(''call.php?category=fruits&amp;fruitid=7890&amp;'',detailFruit,false);">bananas</a><img src="http://imagehosting.com/images/fru_7890.png"></li>
        </ul>';
$dom = new DOMDocument;
$dom->strictErrorChecking = FALSE;
$dom->loadHTML($html);
$xml = simplexml_import_dom($dom);
# xpath to find list items
$items = $xml->xpath("//ul/li");
$regex = "~getit'('([^']+)'')~";
# loop over the items
foreach ($items as $item) {
    $title = $item->a->__toString();
    $imgLink = $item->img["src"];
    $jsLink = $item->a["onclick"];
    preg_match_all($regex, $jsLink, $matches);
    $jsLink = $matches[1][0];
    echo "Title: $title, imgLink: $imgLink, jsLink: $jsLink'n";
    // output: Title: mango season, imgLink: http://imagehosting.com/images/fru_123456.png, jsLink: call.php?category=fruits&fruitid=123456&
    //         Title: bananas, imgLink: http://imagehosting.com/images/fru_7890.png, jsLink: call.php?category=fruits&fruitid=7890&
}
?>
