[Qgis-developer] Python - granular access to rules in rule-based renderer

[Tom Chadwin]

I'm implementing rule-based rendering in qgis2leaf. I know I can get the
filterExpressions with:

qgis.utils.iface.mapCanvas().layers().rendererV2().rootRule().children().filterExpression()

However, filterExpressions are in "SQL-like" syntax. I need to transform
these into JavaScript:

QGIS:  "name"  LIKE '%a%'
JS: feature.properties.name.indexOf('a') != -1

At the moment, I am facing a whole load of messy regexps to cover all
possible expressions (probably impossible). Is there more granular access to
the filterExpression than retrieving the whole string? That could allow me
to build the JS programmatically, which could be possible.
