XML_Util::collapseEmptyTags()

Description

This method collapses empty tags like <foo></foo> with the short version <foo/> by applying a regular expression. This is especially helpful when dealing with XHTML-documents, as there is an important difference in rendering these tags in the browser.

This method has been added in XML_Util 1.1.0.

Parameter

• string $string - string, in which empty tags should be collapsed

• integer $mode - collapse all empty tags (XML_UTIL_COLLAPSE_ALL) or only XHTML tags (XML_UTIL_COLLAPSE_XHTML_ONLY).

Return value

string string with collapsed empty tags

Note

This function should be called statically.
