What is libxmlb

XML is slow to parse and strings inside the document cannot be memory mapped as they do not have a trailing NUL char. The libxmlb library takes XML source, and converts it to a structured binary representation with a deduplicated string table – where the strings have the NULs included. This allows an application to mmap the binary XML file, do an XPath query and return some strings without actually parsing the entire document. This is all done using (almost) zero allocations and no actual copying of the binary data.
