dompdf
dompdf is an HTML-to-PDF converter. At its heart, dompdf is (mostly) a CSS 2.1-compliant HTML layout and rendering engine written in PHP. It is a style-driven renderer: it will download and read external stylesheets, inline style tags, and the style attributes of individual HTML elements. It also supports most presentational HTML attributes. PDF rendering is currently provided either by PDFLib or by a bundled version of the R&OS CPDF class written by Wayne Munro. (Some important changes have been made to the R&OS class, however). In order to use PDFLib with dompdf, the PDFLib PECL extension is required. Using PDFLib improves performance and reduces the memory requirements of dompdf somewhat, while the R&OS CPDF class, though slightly slower, eliminates any dependencies on external PDF libraries. Supports external stylesheets, either locally or through HTTP/FTP. Supports complex tables, including row & column spans, separate & collapsed border models, and individual cell styling.

Our subprojects use the Java and C++ programing languages to implement the XSLT libraries. The Xalan-Java 2.7.2 was released in April 2014. You can download the current release the current Xalan-Java 2.7.2 release for your development. The current work in progress can be found in the subversion repository. The current release fixes a security issue that was registered against version 2.7.1. The old Xalan-J 2.7.1 distributions are still available on the Apache Archives. This is a mature project. There has been some discussion about supporting XPath-2. We could use your support in this major rework of the library. You can follow the efforts and post your own contributions on the Java users and developers mail lists.
