PHP - DOM 提取锚元素的一部分

Question

不需要

第一个td。如果我循环可以枚举单元格吗？然后滑动例如 TD1 ？

// [Download simple_html_dom.php][1]
include "simple_html_dom.php";
$table = '<table>
 <tr bgcolor="#F3F3F3" height="22" style="height:25px">
// The first  td not needed          
<td width="20"></td>
// The second td need the node value. 
<td width="295" ><a href="/projecten/482039/N1.asp">a needed cell 1</a>      
</td>   
// The third td need the user from it.
<td width="90"><center><a href="?p=companyprofile&user=abcd" target="_blank"></a>   
</center></td>       

   //*******************************************************************************
   //and so on and so on till eod   
   <tr bgcolor="#FFFFFF" height="22" style="height:25px">
   <td width="20"></td>
   <td width="295" ><a class="d_link" href="/projecten/482320/xxx.asp">xxx</a></td>
   <td width="90"><center><a href="?p=companyprofile&user=yyyyy"         
    target="_blank"></a></center></td>    <td width="120" ><span     
    class="d_tekst">Brussel</span></td>    <td width="65" ><span 
    class="d_tekst">13:54</span></td>    <td width="120" ><font face="Verdana" </small>
    color="#808080"><small><small>0  &nbsp;(<font color="#008080">nieuw project</font>)     
    </small>        </font></td></tr>    
</table>';
$html = str_get_html($table);

header('Content-type: application/ms-excel');
header('Content-Disposition: attachment; filename=sample.csv');
$fp = fopen("php://output", "w");
foreach($html->find('tr') as $element)
{ 
    $td = array();
 //foreach( $element->find('td') as $row)  
 //there must be another way
 //I want to read them one bij one. 
 //Well the fields are put in the array.  

{
        $td [] = $row->plaintext;
    }
    fputcsv($fp, $td);
}

fclose($fp);

问题我需要提取标签名称和节点值，我需要将它们放在一起。以便第 1 行中的用户对应于第 1 行中的其他字段。例如项目。

Answer 1

像这样做...

<?php
$html='<td><a href="?p=companyprofile&user=abcd" target="_blank"></a></td>';
$dom = new DOMDocument;
@$dom->loadHTML($html);
foreach ($dom->getElementsByTagName('a') as $tag) {
        parse_str($tag->getAttribute('href'));
}
echo $user; //"prints" abcd

Answer 2

我会使用 jquery， http：//jquery.com，来做到这一点。

    $(document).ready(function(){
        var userArray = new Array();
        $('a').each(function(){
             var href_text = $(this).attr('href');
             if( href_text.indexOf('user=')>=0 ){
                  var index_of_username = href_text.indexOf('user=') + 5;
                  var user_name = href_text.substring(index_of_username);
                  userArray.push(user_name);
             }
        });
        //console.log(userArray);
    });

对阵列执行任何操作。删除控制台上的注释.log以测试在调试模式下查看数组输出。
