Issues importing nodes containing taxonomy terms with &/&amp; using feeds
I am using Feeds XPath Parser to import an XML file that contains a couple of fields that I then map to terms in two different vocabularies. It looks like the parser removes ampersands before Feeds Tamper kicks in. This leaves the terms with three spaces where previously there was a space, an ampersand and another space.

My solution - was to create a Find Replace tamper plugin that looks for three spaces in the imported text and replaces the three spaces with a space, an ampersand and another space.

Not pretty, but it works. Of course, this solution won't work if there are other special characters in the feed that would also be removed. In that case, I'd create multiple Find Replace plugins that look for the specific text strings, such as "Canada   Alaska" and replacing them with the corrected string, i.e. "Canada &amp; Alaska". Even less pretty but ...
