<h3>, <ul> and <p>下のタグを選択するXPathを作成しようとしていますdiv[@class="content"]が、p[position() > 1 and position() < last() - 1]

これまでのところ私はこれを持っています...

//div[@class="content"]/*[self::h3 or self::ul or self::p[position() > 1 and position() < last() - 1]]//text()

しかし、それは機能しません。

HTMLは次のとおりです：https ：//gist.github.com/umrashrf/5167711

OK あなたの XML は整形式ではなかったので、まずこれを修正しました。

私があなたの質問を正しく理解していれば、div[@class="content"] の子ノードであるすべての h3、ul、および p タグを見つけようとしており、選択された各子ノードは [position() > 1] の条件を満たさなければなりません。および position() < last() - 1]。このために、この単一の XPATH で十分だと思います：

//div[@class="content"]/h3[position() > 1 and position() < last() - 1]  |        
//div[@class="content"]/p[position() > 1 and position() < last() - 1]  |  
//div[@class="content"]/ul[position() > 1 and position() < last() - 1]
