Careful with the XMLStreamReader#getText()!

Let's read the tags content in following XML snippet:

<tag>foo&boo</tag>

with the single call to (supposing everything is initialized correctly up to this point):

xmlStreamReader.getText()

We expect the string 'foo&boo' as result, right?

No! The return value is (or may be) just 'foo'. XMLStreamReader#getText() is allowed to break the text content into several chunks! For above example, we have 3 xml events (of type CHARACTER) sent one after another: foo, &, boo.

Use getText() in a loop to concatenate chunks and retrieve the whole text content. Or use getElementText() :)

If the property javax.xml.stream.isCoalescing is set to true element content must be coalesced and only one CHARACTERS event must be returned for contiguous element content or CDATA Sections.
