Is there a way you can get all get all children of a parent with a specific attribute value using xpath, for instance if i wanted to get all the children of the first <b> below i could write 

/a/b[0]/c

but is there a way i can do that using a fixed attribute value, something like 

/a/b=ref:123/c

so that i wouldn't matter were in the feed that instance of <b> would be

XML

    <a>
      <b ref="123"></b>
        <c></c>
        <c></c>
        <c></c>
      <b></b>

      <b ref="456"></b>
        <c></c>
        <c></c>
        <c></c>
      <b></b
    </a>

您可以使用如下固定值执行此操作：

/a/b[@ref='123']/c
