I'm using this code to parse strings. When string is returned by this function, it has some added tags:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">
<html><body><p>Some photos<br><br><br><br><br></p></body></html>
Is there any way to avoid this and to have clean string returned? This input string is just for example, in usage it can be any html string.

a simple google search answers this question - the doctype is a declaration and not an an element tag. It simply informs the browser about the page and how to render it - specifically that is a html5 configured document.
Definition and Usage DOCTYPE> declaration. The declaration is not an HTML tag. It is an "information" to the browser about what document type to expect.
An HTML tag is a piece of markup language used to indicate the beginning and end of an HTML element in an HTML document. As part of an HTML element, HTML tags help web browsers convert HTML documents into web pages.
Hey why not answer a 9 year old question? PHP version 5.4 (released 3 years after this question was asked) added the options parameter to DomDocument::loadHTML(). With it you can do this:
$dom = new DomDocument();
$dom->loadHTML($string, LIBXML_HTML_NODEFDTD | LIBXML_HTML_NOIMPLIED);
// do stuff
echo $dom->saveHTML();
We pass two constants: LIBXML_HTML_NODEFDTD says not to add a document type definition, and LIBXML_HTML_NOIMPLIED says not to add implied elements like <html> and <body>.
