|
|
// Synopsis: This function is used to filter HTML tags from a block of
|
|
// text. Based on the flags the filtering routine can be used
|
|
// to filter tags out, disable them, and can do a few other
|
|
// types of filtering.
|
|
//
|
|
// Arguments: szContent - This is the block of text that should be
|
|
// filtered. The filtering is done in place.
|
|
// Therefore depending on the flags, the block
|
|
// may grow and there must be enough space in
|
|
// the buffer for the expansion.
|
|
// dwMaxLen - This is the size of the buffer, and any
|
|
// can not exceeed these limits.
|
|
// iFilterHow - This controls what filtering process is
|
|
// applied to the data.
|
|
// pszNewBuffer- This will hold the adress of the dynamic
|
|
// buffer if there was a need to allocate one
|
|
// dwNewBufferSize - if not 0 and the initial string is not
|
|
// large enough to hold the result, a new
|
|
// buffer of that size will be allocated
|
|
//
|
|
//
|
|
// Returns: HRESULT
|
|
//
|
|
// S_OK - means that the data was successfully filtered and
|
|
// enough space existed to perform all required
|
|
// modifications to the data.
|
|
//
|
|
// Notes: The grsValidTags table is used to determine which tags
|
|
// and attributes are allowed.
