属性中的简单HTML Dom空间

my code is the following

foreach($html->find('div[class=this attribute]') as $itemtitle) {
    echo $itemtitle;
}

I have a space in the middle of the attribute and so my code seems to not be working. Is there a way to get around the space so it picks it up? The space as to stay.

HTML class names actually cannot have spaces. Spaces delimit multiple classes, so you're actually giving the element two classes: this and attribute.

So, find elements with both classes. This should do the trick:

foreach($html->find('div.this.attribute') as $itemtitle) {
    echo $itemtitle;
}

(The . is a shorthand for class.)

Actually, your original code as posted will work fine. You've got an error somewhere else in your code—$html does not contain the necessary parsed HTML. Could you post that section of your code?

Yes, just quote it:

foreach($html->find('div[class="this attribute"]') as $itemtitle) {
    echo $itemtitle;
}

Try:

find('div[class="this attribute"]')

Since you are looking at the class attribute you could use:

foreach($html->find('div.this.attribute') as $itemtitle) {
    echo $itemtitle;
}

Which will test that it has both the classes this and attribute, but not necessarily separated by a single space in the attribute (could have other classes in between, before, and after, and the order may be reversed like class="attribute this").
