element qualifier
open element namespace-modifier? (element-name | element-name-list) (of element-expression )?
The element qualifier open element selects the current element or one of its ancestors using element-name, or by using the first name in element-name-list that matches the current element or
one of its ancestors. If there is more than one opened element with the same name in the element stack of the
currently-active parse, it will always refer to the innermost one.
For example, in the following XML fragment, when parsing the innermost title element,
<manual> <chapter> <title>First Chapter</title> <p>Introduction paragraph</p> <section id="S01.01"> <title>First Section</title> <section id="昭和01年01月01日"> <title>Nested Section</title> ... </section> ... </section> </chapter> </manual>
open element can refer to elements title, section,
chapter, or manual. Additionally, when parsing the innermost title, the
expression attribute "id" of open element "section" would evaluate to 昭和01年01月01日.
