```
import lxml.html

doc = lxml.html.document_fromstring("""
    <nav class="Paging">
            <a href="/women/dresses/cat/4?page=1" class="active">1</a>
            <a href="/women/dresses/cat/4?page=2">2</a>
            <a href="/women/dresses/cat/4?page=2" rel="next">Next »</a>
    </nav>
""")
res = doc.xpath('//nav[@class="Paging"][position() = 1]/a[position() = last() and @rel != "next"]/text()')

print(res)
