提取文本形式与特定属性

Question

我想写的XPath，将选择下div[@class="content"]但p[position() > 1 and position() < last() - 1]

到目前为止，我有这个<h3>, <ul> and <p>标签嵌套节点....

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

但它不没有工作。

确定你的XML并没有很好地形成，所以我固定的这首。

<?xml version="1.0" encoding="UTF-8"?> 
<div class="content">

</div> 

现在，如果我正确地理解你的问题，你想找到所有的H3，UL和p标签，这是DIV的子节点[=“内容” @类]每个选定子节点必须满足条件[position（）> 1和position（）< last（） - 1]。对于这个我认为这个单一的XPATH将做到：

//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]
