xpaf开源解析框架

XPath-based Parsing Framework (XPaF) 是一个简单、方便的开源解析框架，便于从 HTML 和 XML 文档中提取语法上的相关性(subject-predicate-object triples)。

代码示例：

<table>

  <tr>

    <td class="name">Aaron</td>

    <td class="occ">Engineer</td>

  </tr>

  <tr>

    <td class="name">Jennifer</td>

    <td class="occ">Archeologist</td>

  </tr>

</table>

parser_name: "my_parser"

relation_tmpls {

  subject: "//td[@class='name']"

  predicate: "occupation"

  object: "//td[@class='occ']"



  subject_cardinality: MANY

  object_cardinality: MANY

}
