Parameters:
string Content with subpart wrapped in fx. "###CONTENT_PART###" inside.
string Marker string, eg. "###CONTENT_PART###"
array If $subpartContent happens to be an array, it's [0] and [1] elements are wrapped around the content of the subpart (fetched by getSubpart())

Checks whether block/solo tags are found in the correct amounts in HTML content Block tags are tags which are required to have an equal amount of start and end tags, eg. "<table>...</table>" Solo tags are tags which are required to have ONLY start tags (possibly with an XHTML ending like ".../>") NOTICE: Correct XHTML might actually fail since "<br></br>" is allowed as well as "<br/>". However only the LATTER is accepted by this function (with "br" in the "solo-tag" list), the first example will result in a warning. NOTICE: Correct XHTML might actually fail since "<p/>" is allowed as well as "<p></p>". However only the LATTER is accepted by this function (with "p" in the "block-tag" list), the first example will result in an ERROR! NOTICE: Correct HTML version "something" allows eg.

and to be NON-ended (implicitly ended by other tags). However this is NOT accepted by this function (with "p" and "li" in the block-tag list) and it will result in an ERROR!

Parameters:
string HTML content to analyze
string Tag names for block tags (eg. table or div or p) in lowercase, commalist (eg. "table,div,p")
string Tag names for solo tags (eg. img, br or input) in lowercase, commalist ("img,br,input")
Returns:
array Analyse data.

t3lib_parsehtml::HTMLcleaner ( content,
tags = array(),
keepAll = 0,
hSC = 0,
addConfig = array() 
)

Function that can clean up HTML content according to configuration given in the $tags array.

Initializing the $tags array to allow a list of tags (in this case ,,<U> and ), set it like this: $tags = array_flip(explode(',','b,a,i,u')) If the value of the $tags[$tagname] entry is an array, advanced processing of the tags is initialized. These are the options:

$tags[$tagname] = Array( 'overrideAttribs' => '' If set, this string is preset as the attributes of the tag 'allowedAttribs' => '0' (zero) = no attributes allowed, '[commalist of attributes]' = only allowed attributes. If blank, all attributes are allowed. 'fixAttrib' => Array( '[attribute name]' => Array ( 'set' => Force the attribute value to this value. 'unset' => Boolean: If set, the attribute is unset. 'default' => If no attribute exists by this name, this value is set as default value (if this value is not blank) 'always' => Boolean. If set, the attribute is always processed. Normally an attribute is processed only if it exists 'trim,intval,lower,upper' => All booleans. If any of these keys are set, the value is passed through the respective PHP-functions. 'range' => Array ('[low limit]','[high limit, optional]') Setting integer range. 'list' => Array ('[value1/default]','[value2]','[value3]') Attribute must be in this list. If not, the value is set to the first element. 'removeIfFalse' => Boolean/'blank'. If set, then the attribute is removed if it is 'false'. If this value is set to 'blank' then the value must be a blank string (that means a 'zero' value will not be removed) 'removeIfEquals' => [value] If the attribute value matches the value set here, then it is removed. 'casesensitiveComp' => 1 If set, then the removeIfEquals and list comparisons will be case sensitive. Otherwise not. ) ), 'protect' => '', Boolean. If set, the tag <> is converted to < and > 'remap' => '', String. If set, the tagname is remapped to this tagname 'rmTagIfNoAttrib' => '', Boolean. If set, then the tag is removed if no attributes happend to be there. 'nesting' => '', Boolean/'global'. If set true, then this tag must have starting and ending tags in the correct order. Any tags not in this order will be discarded. Thus '' will be converted to ''. Is the value 'global' then true nesting in relation to other tags marked for 'global' nesting control is preserved. This means that if and are set for global nesting then this string '' is converted to '' )

Parameters:
string $content; is the HTML-content being processed. This is also the result being returned.
array $tags; is an array where each key is a tagname in lowercase. Only tags present as keys in this array are preserved. The value of the key can be an array with a vast number of options to configure.
string $keepAll; boolean/'protect', if set, then all tags are kept regardless of tags present as keys in $tags-array. If 'protect' then the preserved tags have their <> converted to < and >
integer $hSC; Values -1,0,1,2: Set to zero= disabled, set to 1 then the content BETWEEN tags is htmlspecialchar()'ed, set to -1 its the opposite and set to 2 the content will be HSC'ed BUT with preservation for real entities (eg. "&amp;" or "&#234;")
array Configuration array send along as $conf to the internal functions ->processContent() and ->processTag()
Returns:
string Processed HTML content
