The event-driven model of SAX is useful for XML parsing, but it does have certain drawbacks. Virtually any kind of XML validation requires access to the document in full. . The most trivial example is that an attribute declared in the DTD to be of type IDREF, requires that there be only one element in the document that uses the same value for an ID attribu
libxml2 is a software library for parsing XML documents. It is also the basis for the libxslt library which processes XSLT-1.0 stylesheets. Description
Unlike the DOM parser, the SAX parser does not create an in-memory representation of the XML document and so runs faster and uses less memory. Instead, the SAX parser informs clients of the XML document structure by invoking callbacks, that is, by invoking methods on an DefaultHandler instance provided to the parser.
Streaming API for XML (StAX) is an application programming interface to read and write XML documents, originating from the Java programming language community. Traditionally, XML APIs are either: DOM based - the entire document is read into memory as a tree structure for random access by the calling application
Expat is a stream-oriented XML 1.0 parser library, written in C, more precisely C99. [3] As one of the first available open-source XML parsers, Expat has found a place in many open-source projects. Such projects include the Apache HTTP Server, Mozilla, Perl, Python and PHP.
XML also provides a mechanism whereby an XML processor can reliably, without any prior knowledge, determine which encoding is being used. [17] Encodings other than UTF-8 and UTF-16 are not necessarily recognized by every XML parser (and in some cases not even UTF-16, even though the standard mandates it to also be recognized).
When used in parsing mode, VTD-XML is a general purpose, high performance [17] XML parser which compares favorably with others: VTD-XML typically outperforms SAX (with NULL content handler) while still providing full random access and built-in XPath support.
TinyXML is a small, simple, operating system-independent [1] XML parser for the C++ language. [2] It is free and open source software, distributed under the terms of the zlib License. [3] TinyXML-2 replaces TinyXML-1 completely and only this version should be used.
