pugixml 1.16 release

Tue, 16 Jun 2026 00:00:00 +0000

pugixml-1.16 is out. This is an anniversary release: pugixml turns 20 this year!

In early 2006, I was evaluating existing XML parsers to parse large COLLADA files quickly and nothing fit the bill; existing DOM parsers were very slow and often cumbersome to use, existing SAX parsers required a tricky parsing flow for documents with many internal references with unspecified order. The most promising existing parser was pugxml (no i), which had a nice API and an interesting parsing approach - but still left a lot of performance on the table so I thought I could quickly patch it up and call it a day. The project was named pugixml (where i stands for improved) in late May 2006.

The first version was assigned a number 0.1 in July, and was used in a few internal projects. It was tiny: 1800 lines of code (plus 700 line header), no tree modification, no Unicode support, no XPath, no compact mode, slower parser. But it was quite useful and so the first version 0.2 was released to the public in November. Originally pugixml was developed in Subversion, until eventually migrating to Git on github.com. Over the following years it quickly gained important features that were missing in the original release; code got faster through continuous tuning; some APIs were adjusted or removed. The library started gaining wider adoption.

In 2010, v1.0 came out. This represented a major stability point: it was the last release to remove or break any APIs, and since then pugixml has remained API-stable and also maintained binary compatibility. Since then, other important improvements have been introduced; for example, in 2015 a major new compilation mode, PUGIXML_COMPACT, allowed to significantly reduce the DOM memory consumption at a small performance cost with no change in API/ABI.

Development continues to this day, 20 years later; in some sense, pugixml is “complete” - the library has worked great for the last decade and all critical functionality is there. But it still requires continued maintenance, as new compilers and language features introduce new problems, some latent bugs are occasionally found, and occasional new minor features are being added. What started as a quick excursion turned into a life-long project - here’s to the next decade!

Highlights for this release (read the changelog for details) include:

Add xml_node::ensure_child and xml_node::ensure_attribute that return the child/attribute with the specified name, adding one if it does not exist
PUGIXML_CHARCONV_FLOAT option can be enabled to switch floating point conversions to <charconv>, making conversions locale-independent and improving performance
Several performance improvements (XPath queries, node/attribute lookup) and bug fixes (remove_child stack overflow, load_file integer overflow on 32-bit systems)

pugixml moves to GitHub

Sun, 26 Oct 2014 00:00:00 +0000

pugixml project used to be hosted on Google Code since time immemorial. About a year ago the active development switched to Git but the Subversion repository on Google Code was still maintained via svn-git and the primary way to report issues was via Issue Tracker on Google Code.

Since Google disabled the downloads feature on Google Code, pugixml releases are hosted on github anyway; also git-svn makes some git workflows more complicated. As of this day, pugixml moves to GitHub and Google Code project is no longer maintained.

You can use GitHub’s issue tracker, submit pull requests, use pugixml as Git submodules, etc.

Note that you can still use Subversion to access pugixml repository on github as follows:

svn checkout https://github.com/zeux/pugixml/tags/latest

Please let me know if you find any issues with GitHub’s Subversion access.

pugixml 1.4 release

Fri, 28 Feb 2014 00:00:00 +0000

pugixml-1.4 is finally out. This is a major release with several new features and compatibility improvements (read the changelog for details).

Highlights for this release include:

Improved validation of documents without element nodes
More parsing options (parse_fragment flag to parse XML document fragments, parse_trim_pcdata flag to remove leading/trailing whitespace)
Better integer support for attribute and text nodes (long long types and hexadecimal conversion)
More stack-efficient XPath compilation and evaluation

You can download the source package or get the new version from Subversion using the latest tag (http://pugixml.googlecode.com/svn/tags/latest).

pugixml 1.2 release

Tue, 01 May 2012 00:00:00 +0000

pugixml-1.2 is finally out. This is a major release with lots of new features and compatibility improvements (read the changelog for details).

Enhanced interface for PCDATA manipulation using an xml_text object
C++11 range-based for-loop support for node/attribute iteration
Compatibility improvements for many mobile platforms (including Android, Windows Mobile and other SDKs/devices)

You can download the source package or get the new version from Subversion using the latest tag (http://pugixml.googlecode.com/svn/tags/latest).

All deprecated functions and types were removed
File loading/saving functions can now work with wide character paths

You can download the source package or get the new version from Subversion using the latest tag (http://pugixml.googlecode.com/svn/tags/latest).

New project site

Thu, 14 Oct 2010 00:00:00 +0000

pugixml now has a new home, pugixml.org. This site acts as a frontend for all pugixml-related stuff (downloads, documentation, support and other information). Additionally, there is a news feed, which you can subscribe to via RSS.

All downloads, documentation, Subversion repository and issue tracker are still hosted at Google Code; the existing links still work, and this is not going to change.

pugixml 0.9 release

Sun, 11 Jul 2010 00:00:00 +0000

pugixml-0.9 is out. This is a major release with lots of fixes/improvements (read the changelog for the details). The most important changes are:

Unicode support is completely reworked: now pugixml can be configured to use wchar_t instead of char for all string-based interfaces; also encoding conversion is performed during parsing/saving (with automatic encoding detection). All popular Unicode encodings are supported.
New version features a new documentation, with detailed description of library interface and behavior, more samples, quick-start guide and so on.
There are new functions for loading document from memory; they do not require the input buffer to be null-terminated. Old functions still work, but are deprecated and will be removed in the future version.

Also there are a lot of other changes, including performance and memory consumption improvements.
