Question

我有一个结构如下的xml文件：

<channel>
 <title>abc</title>
 <link>domain.com</link>
 <description>Bla bla.</description>
<item>
  <title>xyz </title>
  <link>domain.com/</link>
<description>
  <table border="1" width="100%"><tr><th colspan="2"></th><th>P</th><th>W</th><th>D</th><th>L</th><th>GF</th><th>GA</th><th>Dif</th><th>Pts</th></tr><tr><td width="7%">1</td><td width="27%"><a target="_blank" href="domain[dot]com/new-york/"/>New York</td><td width="7%"><center>12</center></td><td width="7%"><center>8</center></td><td width="7%"><center>2</center></td><td width="7%"><center>2</center></td><td width="7%"><center>17</center></td><td width="7%"><center>10</center></td><td width="7%"<center>+7</center></td><td width="7%"><center>26</center></td></tr><tr><td width="7%">2</td><td width="27%"><a target="_blank" href="domain[dot]com/lon-don/"/>London</td><td width="7%"><center>12</center></td><td width="7%"><center>6</center></td><td width="7%"><center>4</center></td><td width="7%"><center>2</center></td><td width="7%"><center>22</center></td><td width="7%"><center>12</center></td><td width="7%"><center>+10</center></td><td width="7%"><center>22</center></td></tr></table><br/>
</description>

我使用这段代码来解析PHP中的table data，我成功了：

$url = "link to the above xml file";
$xml = simplexml_load_file($url);
foreach($xml->channel->item as $item){

    $desc = html_entity_decode((string)$item->description);
    $descXML = simplexml_load_string('<desc>'.$desc.'</desc>');
    $html = $descXML->table->asXML();
    $html .= "<hr />";          
    echo $html;
}

但是，它还在table data / array values中包含超链接，它们在输出时分别为domain[dot]com/newyork/和domain[dot]com/london/。

我期望的是我想在输出中输入exclude the hyperlinks，这意味着我只需要诸如Lon Don或New York之类的纯文本。

请在输出中没有超链接。

谢谢

由于您只是在

中显示整个表XML

$html = $descXML->table->asXML();

这包含表的所有标记，如果您只希望一些表数据，则需要做进一步处理以提取该数据...

$xml = simplexml_load_file($url);
foreach($xml->item as $item){

     $desc = html_entity_decode((string)$item->description);
     $descXML = simplexml_load_string('<desc>'.$desc.'</desc>');
     // Loop over each row of the table
     foreach ( $descXML->table->tr as $row ) {
        // If there are td elements
        if ( isset($row->td) )  {
            // Extract the value from the second td element, convert to a string and trim the result
            $html = trim((string)($row->td[1]));
            $html .= "<hr />";
            echo $html;

        }
    }
}

如果您想要除<tr>标记之外的所有<a> XML，则可以将其取消设置（假设它将始终存在）...

     foreach ( $descXML->table->tr as $row ) {
        // If there are td elements
        if ( isset($row->td) )  {
            unset($row->td[1]->a);
            $html = $row->asXML(). "<hr />";
            echo $html;

        }
    }

PHP解析XML内容而不循环超链接
