Just imagine that any tag has a "plaintext" attribute and use standart attribute selectors.

So, HTML:
```
  London is the capital of Great Britain


  Washington is the capital of the USA
```
can be imagined in mind as:
```
  London is the capital of Great Britain


  Washington is the capital of the USA
```
And PHP to resolve your task is just:
```
      London is the capital of Great Britain
    
```
Washington is the capital of the USA '; $html = str_get_html($t); $foo = $html->find('span[plaintext^=London]'); echo "ID: " . $foo[0]->parent()->id; // div1 ?>
(take in mind that "plaintext" for tags is right-padded with a space symbol; this is default behaviour of Simple HTML DOM, defined by constant DEFAULT_SPAN_TEXT)
