次の XPATH式を使用します。

(/article[contains(@class,"module_article")]//@href)[1]

出力:

h/mother-and-baby/2013091914634/vincent-simone-baby-boy-born/

更新（最後の編集による）

/article[contains(@class,"module_article")]/a[1]/@href

デモの例:

<foo>
  <a href='#1'>1</a>
  <bar>
  <a href='#2'>2</a>
  </bar>
</foo>
<foo>
  <a href='#3'>3</a>
  <baz> <a href='#4'>4</a> </baz>
</foo>

XPATH

/foo/a[1]/@href

出力：
