Sort of a two part question but maybe one answers the other. I'm trying to get a piece of information out of an
<div id="foo">
<div class="bar"><a data1="xxxx" data2="xxxx" href="http://foo.bar">Inner text"</a>
<div class="bar2"><a data3="xxxx" data4="xxxx" href="http://foo.bar">more text"</a>
Here is what I'm using now.
$articles = array();
$html=file_get_html('http://foo.bar');
foreach($html->find('div[class=bar] a') as $a){
$articles[] = array($a->href,$a->innertext);
}
This works perfectly to grab the href and the inner text from the first div class. I tried adding a $a->data1 to the foreach but that didn't work.
How do I grab those inner data tags at the same time I grab the href and innertext.
Also is there a good way to get both classes with one statement? I assume I could build the find off of the id and grab all the div information.
Thanks
To grab all those attributes, you should before investigate the parsed element, like this:
foreach($html->find('div[class=bar] a') as $a){
var_dump($a->attr);
}
...and see if those attributes exist. They don't seem to be valid HTML, so maybe the parser discards them.
If they exist, you can read them like this:
foreach($html->find('div[class=bar] a') as $a){
$article = array($a->href, $a->innertext);
if (isset($a->attr['data1'])) {
$article['data1'] = $a->attr['data1'];
}
if (isset($a->attr['data2'])) {
$article['data2'] = $a->attr['data2'];
}
//...
$articles[] = $article;
}
To get both classes you can use a multiple selector, separated by a comma:
foreach($html->find('div[class=bar] a, div[class=bar2] a') as $a){
...
I know this question is old, but the OP asked how they could get all the attributes in one statement. I just did this for a project I'm working on.
You can get all the attributes for an element with the getAllAttributes()
method. The results are automatically stored in an array property called attr
.
In the example below I am grabbing all links but you can use this with whatever you want. NOTE: This also works with data-
attributes. So if there is an attribute called data-url
it will be accessible with $e->attr['data-url']
after you run the getAllAttributes
method.
In your case the attributes your looking for will be $e->attr['data1']
and $e->attr['data2']
. Hope this helps someone if not the OP.
Get all Attributes
$html = file_get_html('somefile.html');
foreach ($html->find('a') as $e) { //used a tag here, but use whatever you want
$e->getAllAttributes();
//testing that it worked
print_r($e->attr);
}
Check this code
<?php
$html = file_get_html('somefile.html');
foreach ($html->find('a') as $e) {
$filter = $e->getAttribute('data-filter-string');
}
?>
