HtmlAgilityPack by: ZZZ Projects, Simon Mourrier, Jeff Klawiter, Stephan Grell

This is an agile HTML parser that builds a read/write DOM and supports plain XPATH or XSLT (you actually don't HAVE to understand XPATH nor XSLT to use it, don't worry...). It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant with "real world" malformed HTML. The object model is very similar to what proposes System.Xml, but for HTML documents (or streams).

High performance x86 (16/32/64-bit) instruction decoder, encoder and formatter. It can be used for static analysis of x86/x64 binaries, to rewrite code (eg. remove garbage instructions), to relocate code or as a disassembler. - Supports all Intel and AMD instructions - The decoder doesn't allocate any memory and is 2x-5x+ faster than other similar libraries written in C or C# - Small decoded instructions, only 32 bytes - The formatter supports masm, nasm and gas (AT&T) and there are many options to customize the output - The encoder can be used to re-encode decoded instructions at any address - The block encoder encodes a list of instructions and optimizes branches to short, near or 'long' (64-bit: 1 or more instructions) - API to get instruction info, eg. read/written registers, memory and rflags bits; CPUID feature flag, flow control info, etc - All instructions are tested (decode, encode, format, instruction info) License: MIT
