Beautiful Soup is a Python package for parsing HTML and XML documents, including those with malformed markup. It creates a parse tree for documents that can be used to extract data from HTML, [3] which is useful for web scraping. [2] [4]
Written in the C programming language, libxml2 provides bindings to C++, Ch, [3] XSH, C#, Python, Swift, Kylix/Delphi and other Pascals, Ruby, Perl, Common Lisp, [4] and PHP. [5] It was originally developed for the GNOME project , but can be used outside it. libxml2's code is highly portable [ 6 ] since it only depends on standard ANSI C ...
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
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, [ 1 ] and can be used to compute values (e.g., strings , numbers, or Boolean values ) from the content of an XML document.
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. It is also bound in many other languages.
It is used to parse source code into concrete syntax trees usable in compilers, interpreters, text editors, and static analyzers. [1] [2] It is specialized for use in text editors, as it supports incremental parsing for updating parse trees while code is edited in real time, [3] and provides a built-in S-expression query system for analyzing ...
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
Efficient XML Interchange (EXI) is a binary XML format for exchange of data on a computer network. It was developed by the W3C's Efficient Extensible Interchange Working Group and is one of the most prominent efforts to encode XML documents in a binary data format, rather than plain text. Using EXI format reduces the verbosity of XML documents ...
