Macro or equivalent in reStructuredText?

.. raw:: html

    <form action="txmt://open/?url=file:///Users/smcho/smcho/works/prgtask/ni/gtest_boost_options/readme.txt">
    <button type="submit">Edit</button>
    </form>

Is there any macro or equivalent in reStructuredText so that I can get the same result, for example?

.. form :: /Users/smcho/smcho/works/prgtask/ni/gtest_boost_options/readme.txt
