string XML_Util::collapseEmptyTags (
string $string
, integer $mode = XML_UTIL_COLLAPSE_ALL
)
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.
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).
string string with collapsed empty tags
This function should be called statically.
