LXP provides a core set of features that include external file inclusion, XML parsing, and a direct SQL interface to
PostgreSQL. As of Version 0.8, SQL execution is performed with either a dynamic or persistent connection to the PostgreSQL
RDBMS.
LXP also supports a few more advanced techniques commonly found in programming languages, such as variable setting,
insertion and substitution, arrays, branching logic, loop iteration, and a basic search-and-replace variable formatting
interface.
