Validating parser xml

As of release 2.4.16, libxml2 passed all 1800+ tests from the OASIS XML Tests Suite.

Extensible Markup Language (XML) is a set of rules for encoding documents in machine-readable form.

XML is a popular format for sharing data on the internet.

Uploading and parsing XML data is a common task for network-connected apps.

This lesson explains how to parse XML documents and use their data. The first step in parsing a feed is to decide which fields you're interested in. START_TAG) { continue; } String name = Name(); // Starts by looking for the entry tag if (name.equals("entry")) { entries.add(read Entry(parser)); } else { skip(parser); } } return entries; }public static class Entry { public final String title; public final String link; public final String summary; private Entry(String title, String summary, String link) { this.title = title; this.summary = summary; = link; } } // Parses the contents of an entry. START_TAG) { continue; } String name = Name(); if (name.equals("title")) { title = read Title(parser); } else if (name.equals("summary")) { summary = read Summary(parser); } else if (name.equals("link")) { link = read Link(parser); } else { skip(parser); } } return new Entry(title, summary, link); } // Processes title tags in the feed.

The parser extracts data for those fields and ignores the rest. If it encounters a title, summary, or link tag, hands them off // to their respective "read" methods for processing. private Entry read Entry(Xml Pull Parser parser) throws Xml Pull Parser Exception, IOException { parser.require(Xml Pull Parser. private String read Title(Xml Pull Parser parser) throws IOException, Xml Pull Parser Exception { parser.require(Xml Pull Parser.

Here is an excerpt from the feed that's being parsed in the sample app. START_TAG, ns, "entry"); String title = null; String summary = null; String link = null; while (parser.next() ! START_TAG, ns, "title"); String title = read Text(parser); parser.require(Xml Pull Parser.

"Programming with libxml2 is like the thrilling embrace of an exotic stranger." Mark Pilgrim Libxml2 is the XML C parser and toolkit developed for the Gnome project (but usable outside of the Gnome platform), it is free software available under the MIT License.

XML itself is a metalanguage to design markup languages, i.e.text language where semantic and structure are added to the content using extra "markup" information enclosed between angle brackets. Though the library is written in C a variety of language bindings make it available in other environments.Libxml2 is known to be very portable, the library should build and work without serious troubles on a variety of systems (Linux, Unix, Windows, Cyg Win, Mac OS, Mac OS X, RISC Os, OS/2, VMS, QNX, MVS, Vx Works, ...) Libxml2 implements a number of existing standards related to markup languages: In most cases libxml2 tries to implement the specifications in a relatively strictly compliant way.Each post to Stack appears in the feed as an parse(Input Stream in) throws Xml Pull Parser Exception, IOException { try { Xml Pull Parser parser = Pull Parser(); Feature(Xml Pull Parser. END_TAG, ns, "title"); return title; } // Processes link tags in the feed.FEATURE_PROCESS_NAMESPACES, false); Input(in, null); Tag(); return read Feed(parser); } finally { in.close(); } } ... private String read Link(Xml Pull Parser parser) throws IOException, Xml Pull Parser Exception { String link = ""; parser.require(Xml Pull Parser.START_TAG, ns, "link"); String tag = Name(); String rel Type = Attribute Value(null, "rel"); if (tag.equals("link")) { if (rel Type.equals("alternate")){ link = Attribute Value(null, "href"); Tag(); } } parser.require(Xml Pull Parser.
