I am currently using PHP's file_get_contents($url)
to fetch content from a URL. After getting the contents I need to inspect the given HTML chunk, find a 'select'
that has a given name attribute, extract its options, and their values text. I am not sure how to go about this, I can use PHP's simplehtmldom class to parse html, but how do I get a particular 'select' with name 'union'
<span class="d3-box">
<select name='union' class="blockInput" >
<option value="">Select a option</option> ..
Page can have multiple 'select' boxes and hence I need to specifically look by name attribute
<?php
include_once("simple_html_dom.php");
$htmlContent = file_get_contents($url);
foreach($htmlContent->find(byname['union']) as $element)
echo 'option : value';
?>
Any sort of help is appreciated. Thank you in advance.
Try this PHP code:
<?php
require_once dirname(__FILE__) . "/simple_html_dom.php";
$url = "Your link here";
$htmlContent = str_get_html(file_get_contents($url));
foreach ($htmlContent->find("select[name='union'] option") as $element) {
$option = $element->plaintext;
$value = $element->getAttribute("value");
echo $option . ":" . $value . "<br>";
}
?>
how about this:
$htmlContent = file_get_html('your url');
$htmlContent->find('select[name= "union"]');
in object oriented way:
$html = new simple_html_dom();
$htmlContent = $html->load_file('your url');
$htmlContent->find('select[name= "union"]');
From DOMDocument documentation: http://www.php.net/manual/en/class.domdocument.php
$html = file_get_contents( $url );
$dom = new DOMDocument();
$dom->loadHTML( $html );
$selects = $dom->getElementsByTagName( 'select' );
$select = $selects->item(0);
// Assuming all children are options.
$children = $select->childNodes;
$options_values = array();
for ( $i = 0; $i < $children->length; $i++ )
{
$item = $children->item( $i );
$options_values[] = $item->nodeValue;
}
