Few examples with HTML SIMPLE DOM - php

Question

i have some problems with html simple dom and dont know how to get some specific data, i read manual and try by my self, but it looks i miss something so hope somebody can help me.
1th problem:
HTML:
<div>
<h4>Režie:</h4>
<span data-truncate="60">
Ridley Scott
</span>
</div>
<div>
<h4>Scénář:</h4>
<span data-truncate="60">
William Monahan
</span>
</div>
<div>
<h4>Kamera:</h4>
<span data-truncate="60">
John Mathieson
</span>
</div>
<div>
<h4>Hudba:</h4>
<span data-truncate="60">
Harry Gregson-Williams
</span>
</div>
My PHP code:
$ret = $html->find('span[data-truncate*="60"]'); //rezia
foreach ($ret as $rezia) {
echo "rezia <br/>";
}
But this code print just name and a href from all of this name, and what i need is just name which is under "REŽIE"(Ridley Scott) and "Scénář" (William Monahan)
2th Problem
HTML:
<div id="rating">
<h2 class="average">71%</h2>
<p class="charts">
PHP code:
$percenta = $html->find('h2[class*="average"]'); //pocet ˇ%
foreach ($percenta as $hodnotenie) {
echo "$hodnotenie";
}
What i get from this is 71% and i want just number, not that HTML around, is it possible?
3th problem (the last one:P):
HTML:
<table>
<tr>
<th>
V kinech ČR
od:
</th>
<td class="date">
06.05.2005
</td>
</tr>
<tr>
<th>
V kinech SR
od:
</th>
<td class="date">
05.05.2005
</td>
</tr>
<tr class="separator">
<th>
Na DVD
od:
</th>
<td class="date">
01.10.2005 Bonton
</td>
</tr>
PHP code:
$ret = $html->find('td[class="date"]');
$kino = array();
foreach ($ret as $kino) {
$datum[] = $datum->innertext;
}
echo "$datum[0]";
I get not output from this and i have no idea whats wrong on my code. I just want to get that DATEs (so should be 06.05.2005, 05.05.2005, 01.10.2005)

Answer 1

You didn't load the html, look at this
$html = str_get_html('Some text bla bla bla bla<br /><b>Date</b>: 2012-12-13<br /><br /><b>Name</b>: Peter Novak<br /><b>Hobby</b>: books,cinema,facebook');
foreach($html->find('text') as $t){
if(substr($t, 0, 1)==':')
{
// do whatever you want
echo substr($t, 1).'<br />';
}
}
Output will be
2012-12-13
Peter Novak
books,cinema,facebook
Also, check this one to load a remote site's content
$html = file_get_html('http://heera.it');
// Find all article blocks
foreach($html->find('div.post-entry') as $article) {
echo $article->find('div.post-entry-content h2 a', 0) . '<br />';
echo $article->find('div.post-entry-content p', 0)->plaintext. '<br />';
echo "<hr />";
}
The result will be
