Systems and methods for building and/or simplifying structured-document path-language expressions are described. One of these systems or methods enables a user to graphically select structured-document path-language functions and addresses. With these addresses and functions, a structured-document path-language expression can be built without a user having to fully understand or type in syntax for the expression. Another of these systems or methods simplifies structured-document path-language address and function syntax. This simplification can aid a user in building and easily understanding a structured-document path-language expression.
