When reading in the site element from my xml file using rexml it seems
to be chopping the rest of the text off after the first <br/>
The value in the XML file is below
<Site>123 street<br/>amstown<br/>amserland</Site>
element = REXML::XPath.first(doc, '//Site')
puts element.text #shows 123 Street
How can i get the full data and once i have it i can remove the <br/>
I cant find any information on this???

I'd suggest using a bit more XPath, both text() and a each {} to
iterate through the text nodes (which are distinct):
$ irb -r rexml/document --prompt xmp
a = REXML::Document.new("<Site>123 street<br/>amstown<br/>amserland</Site>")
# => <UNDEFINED> ... </>
REXML::XPath.first(a, '//Site').text
# => "123 street"
REXML::XPath.first(a, '//Site/text()').to_s
# => "123 street"
REXML::XPath.each(a, '//Site/text()') {|el| puts el}
123 street
amstown
amserland
# => ["123 street", "amstown", "amserland"]

Not quite. It gives you the *first* text element.
The value in the XML file is below
<Site>123 street<br/>amstown<br/>amserland</Site>element = REXML::XPath.first(doc, '//Site')
puts element.text #shows 123 Street

You can't find any specific info because there isn't anything specific.
You have an XML element that contains a text node, an empty element named
br, another text node, another empty element named br and another text
node. In the XML world, <br/> is a node like any other.
The REXML::Element.texts method is what you are looking for:
$ irb
irb(main):001:0> require "rexml/document"
=> true
irb(main):002:0> doc=REXML::Document.new("<Site>123 street<br/>amstown<br/
amserland</Site>")
=> <UNDEFINED> ... </>
irb(main):003:0> doc.root.texts
=> ["123 street", "amstown", "amserland"]
irb(main):004:0> doc.root.texts.join " "
=> "123 street amstown amserland"
Enjoy!

Seems like that just REXML::XPath.first(a, '//Site').to_s
returns the whole content.

The assert_xpath plugin wraps that up in this convenient method:
class REXML::Element
def inner_text
return self.each_element( './/text()' ){}.join( '' )
end
end
...
def test_absolve_breaks
a = REXML::Document.new("<Site>123
street<br/>amstown<br/>amserland</Site>")
assert_equal "123 streetamstownamserland", a.inner_text
end
Come to think of it, that's not terribly programmer-friendly! Let's upgrade
it a little...
assert_equal "123 streetamstownamserland", a.inner_text
assert_equal "123 street\namstown\namserland", a.inner_text("\n")
...
def inner_text(interstitial = '')
return self.each_element( './/text()' ){}.join(interstitial)
end
