A:
I don't have nokogiri, but here's an alternative using just basic string manipulation.
html=<<EOF
<body>
<div>some text</div>
I NEED THIS TEXT ONLY
<div>some text</div>
more text here
<div>some text</div>
one more text here
<div>some text</div>
</body>
EOF
p html.split(/<\/*body>/)[1].split(/<\/div>/)[1].split(/<div>/)[0]

**Really?** String manipulation instead of parsing?

O.M.G., if this was a Perl question lightning would have struck. For anything but the most trivial task string manipulation and/or its cousin REGEX will fail badly. For fun search for perl, regex and parsing html.

OP's requirement is trivial. For me, there's no reason to use nokogiri or some other parsing tool.

A:
this returns the first text node within body between two div elements:
/body/text()[
./preceding::element()[1][local-name()="div"] and
./following::element()[1][local-name()="div"]
][1]
should return
I NEED THIS TEXT ONLY

A:
This XPath 1.0:
/body/text()[preceding-sibling::*[1][self::div]]
[following-sibling::*[1][self::div]][1]
Also:
/body/text()[normalize-space()][1]

A:
Use:
/*/div[1]/following-sibling::text()[1]
This selects the first text-node sibling of the first div child of the top element of the document.
