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]
Thus, the minimum memory required for a SAX parser is proportional to the maximum depth of the XML file (i.e., of the XML tree) and the maximum data involved in a single XML event (such as the name and attributes of a single start-tag, or the content of a processing instruction, etc.). This much memory is usually considered negligible. A DOM ...
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 ...
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.
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.
So XML files that rely upon DTD-defined entities will not parse correctly in TinyXML. Though it does handle processing instructions , it has no facilities for handling XSLT stylesheet declarations. That is, it does not apply an XSLT declared in a stylesheet processing instruction to the XML file when parsing it.
xml.dom for Python; XML for <SCRIPT> is a JavaScript-based DOM implementation [16] PHP.Gt DOM is a server-side DOM implementation based on libxml2 and brings DOM level 4 compatibility [17] to the PHP programming language; Domino is a Server-side (Node.js) DOM implementation based on Mozilla's dom.js. Domino is used in the MediaWiki stack with ...
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).
