Extracting from XML with regex

The following regex may also work for extracting strings from XML when a file is uploaded to import:

```
/<\s*?(string|plurals|string-array).*?name\s*?=\s*?"\s*?([^"]+)\s*?".*?>(.*?)<\s*?\/\s*?\1\s*?\s*?>/gis
```

Results:
- \1 = type
- \2 = key/name
- \3 = contents
