Automatic Feed Translation

Using the XSLT file listed below you can automatically translate a foreign language feed into your language, utilizing Google's Translation API, whenever Awasu updates the associated Channel. Here is the list of supported languages.

Customising the XSLT file

Your language

There is a constant in the XSLT file called "yourLanguage" which you can change to a specific two-character language code of your language. If your language is English, the XSLT file below should work well without any modification.

Feed language

There is a constant in the XSLT file called "feedLanguage" which you can change to a specific two-character language code if you know the language of the feed; this will improve Google's language translation accuracy. Leaving the "feedLanguage" constant blank (empty quotation marks: "") should still work as Google will attempt to guess the feed's langauge.
