Boost HTML Library

Written by Andreas Haberstroh

Monday, 03 September 2007

Release of the Boost HTML library, a cross-platform C++ library for reading and writing HTML documents.

License

Boost-HTML is released under the Boost Software License.

Dependencies

Boost::HTML requires Boost version 1.33 or later.

Downloading

The Boost-HTML library is available here.

Using Boost-HTML

The Boost-HTML library is relatively simplistic in design. All read and write operations are based on streams.

#include <boost/html/document.hpp>
#include <iostream>

#include <fstream>
using namespace std;
int main(int argc, char* argv[])
{
fstream ifile("index.html", ios_base::in);
boost::html::document htmlDOM;

htmlDOM.read(ifile);

htmlDOM.write(cout);

return 0;
}

Why did I write Boost-HTML?

I was searching the Internet for a c++ HTML parser library that would create a tree of HTML elements and their attributes. I was looking for an c++ interface similar to JavaScript's DOM. I found plenty of XML parsers (Boost-Property Tree Library, Xerces) and a few HTML parsers that spat out information in a SAX like manner. I just simply couldn't find a C++ library that did what I wanted.

So, I did some reading of the W3C's Core DOM specification and a few other sources and decided to write my own HTML parser. The IDL interface in the Core DOM specification gave me the starting point for my c++ implementation, and that is where I started. Boost-HTML Library is simple, no frills, since it was a Labor Day weekend project. I can read in a document and write it back, almost the same as I read it. I say almost the same, because I decided to use the XHTML notation for elements that are singular in nature, for instance <br />.

With this library, you can also pull out a list of elements by searching for a tag name or a tag id attribute. That was really the main feature I was looking for, pull out all the <a> tags from a document.

Hopefully, you'll find this library useful and tell me about it.

Better yet, if you find a glaring bug, I hope you'll tell me about that too!

What Boost Libraries are Used ?

I've used a few of my favorite Boost libraries:

shared_ptr	Pretty much every element object is encapsulated as a shared_ptr. I like automagic clean up
multi_index	Attributes and element references are placed in multi_index_containers. Makes life easy to look up objects.
hash	Easier to search by a hash, and that is just what I do!
string_algo	Pretty cool library giving Perl like functionality for strings. I personally use the join function a few times.

I want to read the html file and make the DOM out of it .Then modify that and regenerate the html file again out of my DOM tree.Would you PLZ tell me which tarball do I need and How I can do sth like that example?

#include

#include
using namespace std;
int main(int argc, char* argv[])
{
fstream ifile("index.html", ios_base::in);
