yarrrml-parser generates faulty mapping when using xpath functions

[johndoe888]

When parsing

prefixes:
  test: http://www.test.test/

mappings:
  Project:
    sources:
      - [test.xml~xpath, "/"]
    s: test:$(lower-case(test))
    po:
      - [a, test:Test]

with the yarrrml-parser version 1.3.5 I get

@prefix rr: <http://www.w3.org/ns/r2rml#>.
@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>.

The brackets at the end of the line with "{lower-case(test})" are swapped ("})" instead of ")}").

This looks to be a duplicate of #164. The suggested fix is to add a backslash to escape the closing parenthesis:

    s: test:$(lower-case(test\))

[johndoe888]

Okay. Closing this.
