As the need for mutual understanding on an international scale increases, more and more organisations and individuals are seeking comparable information across national and cultural boundaries using research instruments prepared in one language and culture for use in others. For example (taking English as the language in which the research is to be reported): an English-speaking researcher might conduct an interview in a language other than English; a researcher interviews in her primary language which in not English; researcher and participants are fully and fluently bilingual - they slip between the two languages during the interview (Rossman and Rallis, 191). The Localization update module helps you keep your interface translations for core and contributed modules up-to-date by grabbing them from the central Drupal translation repository (localize.drupal.org) or another ============= From (needs to be better incorporated) ============= Alternatively, locally stored translation files can be used as translation source too.By choice, updates are performed automatically or manually.Every time you do a select from process data, it will return the initial value. If you have more than two values, then you need to use the last function within your xpath.Here’s an example of concatenating a list of values separated by commas: node in process data. If the length is greater than 0, it means that it found a value already in process data.Since it’s the first value to be updated, it will not add a comma and just set the variable to the field.
