xmlByteConsumed: @ctxt: an XML parser context

This function provides the current index of the parser relative to the start of the current entity. This function is computed in bytes from the beginning starting at zero and finishing at the size in byte of the file if parsing a file. The function is of constant cost if the input is UTF-8 but can be costly if run on non-UTF-8 input.

Returns the index in bytes from the beginning of the entity or -1 in case the index could not be computed.

xmlCleanupParser()

XMLPUBFUN void XMLCALL xmlCleanupParser

xmlCleanupParser:

This function name is somewhat misleading. It does not clean up parser state, it cleans up memory allocated by the library itself. It is a cleanup function for the XML library. It tries to reclaim all related global memory allocated for the library processing. It doesn't deallocate any document related memory. One should call xmlCleanupParser() only when the process has finished using the library and all XML/HTML documents built with it. See also xmlInitParser() which has the opposite function of preparing the library for operations.

WARNING: if your application is multithreaded or has plugin support calling this may crash the application if another thread or a plugin is still using libxml2. It's sometimes very hard to guess if libxml2 is in use in the application, some libraries or plugins may use it without notice. In case of doubt abstain from calling this function or do it just before calling exit() to avoid leak reports from valgrind !

xmlKeepBlanksDefault: @val: int 0 or 1

Set and return the previous value for default blanks text nodes support. The 1.x version of the parser used an heuristic to try to detect ignorable white spaces. As a result the SAX callback was generating xmlSAX2IgnorableWhitespace() callbacks instead of characters() one, and when using the DOM output text nodes containing those blanks were not generated. The 2.x and later version will switch to the XML standard way and ignorableWhitespace() are only generated when running the parser in validating mode and when the current element doesn't allow CDATA or mixed content. This function is provided as a way to force the standard behavior on 1.X libs and to switch back to the old mode for compatibility when running 1.X client code on 2.X . Upgrade of 1.X code should be done by using xmlIsBlankNode() commodity function to detect the "empty" nodes generated. This value also affect autogeneration of indentation when saving code if blanks sections are kept, indentation is not generated.

Returns the last value for 0 for no substitution, 1 for substitution.
