Expat XML Parser
Fast XML parser library in C
PLEASE NOTE that we are in the process of moving to GitHub: https://github.com/libexpat/libexpat This is James Clark's Expat XML parser library in C. It is a stream oriented parser that requires setting handlers to deal with the structure that the parser discovers in the document.

lxml
The lxml XML toolkit for Python
A Python library for efficient XML and HTML processing, known for speed and compatibility. The lxml XML toolkit is a Pythonic binding for the C libraries libxml2 and libxslt. It is unique in that it combines the speed and XML feature completeness of these libraries with the simplicity of a native Python API, mostly compatible but superior to the well-known ElementTree API. The latest release works with all CPython versions from 3.6 to 3.12. See the introduction for more information about the background and goals of the lxml project. -

decimal
Arbitrary-precision fixed-point decimal numbers in go
Arbitrary-precision fixed-point decimal numbers in go. Note: Decimal library can "only" represent numbers with a maximum of 2^31 digits after the decimal point. The zero-value is 0, and is safe to use without initialization. Addition, subtraction, and multiplication with no loss of precision. Division with specified precision. Database/sql serialization/deserialization. JSON and XML serialization/deserialization. big.Int's API is built to reduce the number of memory allocations for maximal performance. This makes sense for its use-case, but the trade-off is that the API is awkward and easy to misuse. In contrast, it's difficult to make such mistakes with decimal. Decimals behave like other go numbers types: even though a = b will not deep copy b into a, it is impossible to modify a Decimal, since all Decimal methods return new Decimals and do not modify the originals. The downside is that this causes extra allocations, so Decimal is less performant. -

RestSharp
Simple REST and HTTP API Client for .NET
RestSharp is probably the most popular HTTP client library for .NET. Featuring automatic serialization and deserialization, request and response type detection, variety of authentications and other useful features, it is being used by hundreds of thousands of projects. RestSharp passed over 32 million downloads on NuGet, with average daily download count of 10,000. It's being used by many popular OSS projects, including Roslyn and Swagger. The main purpose of RestSharp is to make synchronous and asynchronous calls to remote resources over HTTP. As the name suggests, the main audience of RestSharp are developers who use REST APIs. However, RestSharp can call any API over HTTP (but not HTTP/2), as long as you have the resource URI and request parameters that you want to send comply with W3C HTTP standards. RestSharp can take care of serializing the request body to JSON or XML and deserialize the response. It can also form a valid request URI based on different parameter kinds. -

SimpleXlsxWriter
C++ library for creating XLSX files for MS Excel 2007 and above.
This library represents XLSX files writer for Microsoft Excel 2007 and above. The main feature of this library is that it uses C++ standard file streams. On the one hand it results in almost unnoticeable memory and CPU resources consumption while processing (that may be very useful at saving a large data arrays), but on the other hand it makes unfeasible to edit data that were written. Hence, if using this library the structure of the future report should be known enough. The library is written in C++ with using STL functionality and based on the ZIP library (included), which has a free license: http://www.codeproject.com/Articles/7530/Zip-Utils-clean-elegant-simple-C-Win32 This library is distributed under the terms of the zlib license: http://www.zlib.net/zlib_license.html -

gawk libraries for XML, PostgreSQL,...
Dynamically loaded extension libraries for GNU AWK
The gawkextlib project provides several extension libraries for gawk (GNU AWK), as well as libgawkextlib containing some APIs that are useful for building gawk extension libraries. These libraries enable gawk to process XML data, interact with a PostgreSQL database, use the GD graphics library, and perform unlimited precision MPFR calculations. These extensions work with GNU AWK version 4.1.1 or later. We have created a framework for packaging gawk extensions, and we welcome further contributions. Recent additions include haru, redis, and select for I/O multiplexing. -

data2bin
Create structured binary files from XML data.
Need to create binary files with data for Your program, game etc.? Tired of using hex-editor and editing the file manually with the risk of structure-mismatches? Too lazy to reedit complete file after changing structure members order or size? "data2bin" is a utility that takes: 1. Your structures description (you can use integers of different sizes and endiannesses, null-terminated text strings, fixed-size binary strings, structures, arrays...) 2. Your data in a XML file written down according to defined structure. ... and produces final binary file. It is able to pad Your strings with defined padding, check Your integers' sizes, it can fill default values where You didn't supply data, it can also, for example, put a "blank" array member at the end of an array etc. Whenever You change your structure in Your code, just update the data-description file and "rebuild" Your binary files without touching XML data files! -

XML Unit
XMLUnit provides assertions that help testing code that produces XML.
XMLUnit 2.x Development Moved to GitHub XMLUnit provides help with testing code that creates or consumes XML. XMLUNit 2.x is available for both Java and .NET with a similar API. Development of this version has moved to a GitHub organization[1] with two git repositories for Java and .NET respectively. All discussion about XMLUnit independent of any version will happen on the XMLUnit general mailing list[2]. XMLUnit for Java 1.x is no longer maintained, please use the legacy artifacts of XMLUnit 2.x if you still need APIs compatible with XMLUnit 1.x. We keep using the Sourceforge infrastructure that has served as well for many years to host forums and mailing lists. XMLUnit for .NET 0.x is not maintained any longer.
