解析從錶鏈接用PHP

Question

我用下面的代碼來解析從澳大利亞證券交易所表元素：

<?php 

$dom = new DOMDocument(); 


//load the html 
$html = $dom->loadHTMLFile("http://www.asx.com.au/asx/statistics/prevBusDayAnns.do"); 

    //discard white space 
$dom->preserveWhiteSpace = false; 

    //the table by its tag name 
$tables = $dom->getElementsByTagName('table'); 

    //get all rows from the table 
$rows = $tables->item(0)->getElementsByTagName('tr'); 
    // get each column by tag name 
$cols = $rows->item(0)->getElementsByTagName('th'); 
$row_headers = NULL; 
foreach ($cols as $node) { 
    //print $node->nodeValue."\n"; 
    $row_headers[] = $node->nodeValue; 
} 

$table = array(); 
    //get all rows from the table 
$rows = $tables->item(0)->getElementsByTagName('tr'); 

foreach ($rows as $row) 
{ 
    // get each column by tag name 

    $cols = $row->getElementsByTagName('td'); 

    $companysymbol = $cols->item(0)->nodeValue; 
    $pubtime = $cols->item(1)->nodeValue; 
    $newstitle = $cols->item(3)->nodeValue; 

    $row = array(); 

    echo $companysymbol . '<br>'; 
    echo $pubtime . '<br>'; 
    echo $newstitle . '<br><br>'; 

} 

?> 

的代碼工作正常，但除了呼應$ companysymbol，$ pubtime和$ newstitle我想回顯表格內的鏈接（PDF鏈接）。有人能告訴我如何？

在此先感謝您的幫助！

Answer 1

你需要得到href屬性，然後重新創建鏈接。

(...) 
$pdflink = $cols->item(5)->nodeType === XML_ELEMENT_NODE ? $cols->item(5)->getElementsByTagName('a')->item(0)->getAttribute('href') : ''; 
(...) 
echo "<a href='http://www.asx.com.au$pdflink'>pdf</a>".'<br>'; 

這將創建一個可點擊的鏈接到PDF。
