title: what is the difference between tidy functions parseString(),repairString(),cleanRepair()
body: <p>I have just begun using tidy but i am confused by its functions <code>parseString()</code>, <code>repairString()</code>, <code>cleanRepair()</code>. i have gone through the php.net manual and other sites but can get it? the php manual says that <code>parseString()</code> parses the document stored in a string and <code>repairString()</code> repairs the document stored in a string. But what is the difference between parsing and repairing. the both accept optional parameters and they can be given the same parameters so what is the difference? when to use which function and when both? i have seen in a tutorial,it used both the functions. can somebody help? also point to any useful links if you know. Thanks</p>
