 # todo: haven't looked at the code for years,
 # probably needs some work...
 
+# @@
+#
+# All occurences of contains(...) need some re-work to deal with
+# selectors that involve quote marks, the outer marks should be
+# choosen based on the inner marks and if the string contains
+# both types of quote marks, the string needs to be split up and
+# use concat(...) to put them together again. For example
+#
+#   :contains(\"\'\"\')
+#
+# should become
+#
+#   ... contains(..., concat('"', "'", '"', "'")) ...
+# 
+# This can be done by e.g. the following code
+#
+#   my $result = join ", ", map { /'/ ? qq("$_") : qq('$_') }
+#                           grep length,
+#                           split(/(['"])/, $string);
