I am trying to get the value from the given text, either by a CSS selector or an xpath expression but I don't know whether it's possible to carry this out or not. This is my HTML:
<select name="product" style="width: 430px">
<option value="0" selected="selected"></option>
<option value="3181">389-ds-base</option>
<option value="3511">7-Zip</option>
Let's say I want to get the value 3511 by giving the text.
The reason I want this is because I want to do webcrawling like this:
require_once '/root/PHP/goutte.phar';
use Goutte\Client;
$client = new Client();
$crawler = $client->request('GET', 'https://oval.mitre.org/repository/data/search/');
$form = $crawler->selectButton('Search')->form();
$crawler = $client->submit($form, array('product' => '3511'));
$nodeValues = $crawler->filterXPath('//td[@nowrap][position()>4]/a')->each(function ($node) {
return $node->text();
});
And I don't want to pass the number 3511 as an argument but the text.
Hope I made myself clear, thank you in advance.
The xpath expression string(//option[.="7-Zip"]/@value) will find any <option> element whose text content equals "7-Zip" and return its value attribute as a string.
