USoft Blend  >  Expressions


USoft Blend combines operating system file paths, XML fragments, XPath expressions, SQL statements, JSON fragments, and many more to provide a complete and highly expressive tool for installing, delivering and maintaining instances of USoft applications.

This help section helps you understand the most frequently encountered expression types and their data types. It concentrates on their use in a USoft Blend context. Look elsewhere for tutorials on the languages themselves, for example, on XPath.
