Importing Custom (Trumba ) RSS Feeds into Node
Consider using the Feeds XPath Parser. Here is a quote from its project page:


  Feeds XPath Parser is a Feeds plugin for parsing XML and HTML documents. It enables site builders to leverage the power of Feeds to easily import data from complex, external data sources. Each element you wish to extract is setup using configurable mapping queries, saving time for developers who would otherwise have to code complex, specific-use modules. It also enables end-users to build web scrapers and other useful tools within Drupal.
