我有一个XML下面的模式，我想检索周围的文本(左和右)标记如下(使用JAVA + DOM4j)

<p>
Extensible Markup Language (XML) is a markup language that defines a set of
rules for encoding documents in a format that is both human-readable and machine-
readable <ref id = 1>1</ref>. It is defined in the XML 1.0 Specification produced
by the W3C, and several other related specifications
</p>
<p>
Many application programming interfaces (APIs) have been developed to aid
software developers with processing XML <ref id = 2>2</ref>. data, and several schema
systems exist to aid in the definition of XML-based languages.

我想检索周围标记的文本。例如，这个XML的输出是
<ref id = 1>1</ref>

right:在XML 1.0规范中定义
