Querying Qt Graphs

XPath-like query system, designed for axising Qt but usable elsewhere.

Differences from XPath:

• Leading slash is ignored, since we are always passing in root objects.

Axis specifiers:

• attribute

  @abc -> self.abc

• child

  xyz -> child::xyz

• self

  . -> self

• parent

  .. -> self.parent()

uitools.qpath.qpath(root, query, globals=None)

Return a list of results by applying a query string to a context.

Parameters:

• root (object) – The object to start the search at.
• query (str) – The QPath query to process in the context of the given root.

Return list:

The results.
