{ These are the various options you can configure the parser with. These are
101
chosen such that an option flag of 0 (kCFXMLParserNoOptions) leaves the XML
102
as "intact" as possible (reports all structures; performs no replacements).
103
Hence, to make the parser do the most work, returning only the pure element
104
tree, set the option flag to kCFXMLParserAllOptions.
106
kCFXMLParserValidateDocument -
107
validate the document against its grammar from the DTD, reporting any errors.
108
Currently not supported.
110
kCFXMLParserSkipMetaData -
111
silently skip over metadata constructs (the DTD and comments)
113
kCFXMLParserReplacePhysicalEntities -
114
replace declared entities like <. Note that other than the 5 predefined
115
entities (lt, gt, quot, amp, apos), these must be defined in the DTD.
116
Currently not supported.
118
kCFXMLParserSkipWhitespace -
119
skip over all whitespace that does not abut non-whitespace character data.
120
In other words, given <foo> <bar> blah </bar></foo>, the whitespace between
121
foo's open tag and bar's open tag would be suppressed, but the whitespace
122
around blah would be preserved.
124
kCFXMLParserAddImpliedAttributes -
125
where the DTD specifies implied attribute-value pairs for a particular element,
126
add those pairs to any occurances of the element in the element tree.
127
Currently not supported.

{ These functions are called as a parse progresses.
169
called as new XML structures are encountered by the parser. May return NULL to indicate
170
that the given structure should be skipped; if NULL is returned for a given structure,
171
only minimal parsing is done for that structure (enough to correctly determine its end,
172
and to extract any data necessary for the remainder of the parse, such as Entity definitions).
173
createXMLStructure (or indeed, any of the tree-creation callbacks) will not be called for any
174
children of the skipped structure. The only exception is that the top-most element will always
175
be reported even if NULL was returned for the document as a whole. NOTE: for performance reasons,
176
the node passed to createXMLStructure cannot be safely retained by the client; the node as
177
a whole must be copied (via CFXMLNodeCreateCopy), or its contents must be extracted and copied.
180
called as children are parsed and are ready to be added to the tree. If createXMLStructure
181
returns NULL for a given structure, that structure is omitted entirely, and addChild will
182
NOT be called for either a NULL child or parent.
185
called once a structure (and all its children) are completely parsed. As elements are encountered,
186
createXMLStructure is called for them first, then addChild to add the new structure to its parent,
187
then addChild (potentially several times) to add the new structure's children to it, then finally
188
endXMLStructure to show that the structure has been fully parsed.
190
createXMLStructure, addChild, and endXMLStructure are all REQUIRED TO BE NON-NULL.
192
resolveExternalEntity -
193
called when external entities are referenced (NOT when they are simply defined). If the function
194
pointer is NULL, the parser uses its internal routines to try and resolve the entity. If the
195
function pointer is set, and the function returns NULL, a place holder for the external entity
196
is inserted into the tree. In this manner, the parser's client can prevent any external network
199
handleError - called as errors/warnings are encountered in the data stream. At some point, we will
200
have an enum of the expected errors, some of which will be fatal, others of which will not. If
201
the function pointer is NULL, the parser will silently attempt to recover. The
202
handleError function may always return false to force the parser to stop; if handleError returns
203
true, the parser will attempt to recover (fatal errors will still cause the parse to abort
