Question

我正在使用Simple html dom（http://simplehtmldom.sourceforge.net/）库来实现此功能。

我想解析网站的pre标签内容，我正在使用此代码：

    <?php include '/libraries/simple_html_dom.php' ?>
    <?php
    // Create DOM from URL or file
    $html = file_get_html('testing.html');

     // Find the Text
    foreach($html->find('pre') as $element) 
           echo '<p>' . $element . '<p>';      
    ?>

这是文件＆＃39; testing.html＆＃39;：

的内容

    <html>
    <head>
    </head>
    <body bgcolor="#FFFFFF">
    <pre>
    am.o                 V      1 1 PRES ACTIVE  IND 1 S    
    amo, amare, amavi, amatus  V   [XXXAO]  
    love, like; fall in love with; be fond of; have a tendency to;
    am.as                N      1 1 ACC P F                 
    ama, amae  N  F   [XXXDO]    lesser
    bucket; water bucket; (esp. fireman's bucket);
    am.as                V      1 1 PRES ACTIVE  IND 2 S    
    amo, amare, amavi, amatus  V   [XXXAO]  
    love, like; fall in love with; be fond of; have a tendency to;
    </pre>
    </body>
    </html>

正如您所看到的，预文本有carridge返回，我想在输出中保留。目前这是解析器的输出：

  am.o                 V      1 1 PRES ACTIVE  IND 1 S      amo, amare, amavi, amatus  V   [XXXAO]    love, like; fall in love with; be fond of; have a tendency to;  am.as                N      1 1 ACC P F                   ama, amae  N  F   [XXXDO]    lesser  bucket; water bucket; (esp. fireman's bucket);  am.as                V      1 1 PRES ACTIVE  IND 2 S      amo, amare, amavi, amatus  V   [XXXAO]    love, like; fall in love with; be fond of; have a tendency to;

我该怎么做？

Answer 1

使用echo '<p>' . $element->innerHTML . '<p>';

Answer 2

用BR标签替换换行符。您可以使用nl2br()。

Answer 3

您必须指定文本节点：

foreach($html->find('pre') as $element) 
           echo '<p>' . $element->innertext . '<p>';

Answer 4

事实证明这真的很简单！简单的HTML Dom不是必需的，因为没有像这样的库可以完成：

$file = file_get_contents('testing.html');
$start = '<html>';
$end   = '<pre>';
$string = $file;
$whatwearelookingfor = strstr( substr( $string, strpos( $string, $start) + strlen( $start)), $end, true);
$parsedresult = str_replace($whatwearelookingfor,"",$file);
$parsedresult = str_replace("<html>","",$parsedresult);
$parsedresult = str_replace("</body></html>","",$parsedresult);
echo $parsedresult;

返回pre-Preserving返回的内容！

保留来自<pre> after parsing</pre>的文本中的回车
