XML : select checkbox tag python

If have a XML document like this :

  <!-- Location -->  <w:t>Lokacioni:</w:t>  <w:t>Kucni:</w:t>  <w:t>Extension:</w:t>  <w:t>Hajvali –Prishtinë</w:t>  <w:t>Rr. " Dëshmorët e Gollakut "</w:t>  <w:t>P. N. Prishtinë</w:t>    <!-- Date -->  <w:t>Dat:</w:t>  <w:t>Datum:</w:t>  <w:t>Date:</w:t>  <w:t xml:space="preserve"> </w:t>    <!-- Free text - contains time and description-->  <w:t>1.</w:t><w:t>08:05 Aksident trafiku me dëme materiale Audi dhe Kombi te Kisha Graqanic</w:t>    <!-- Checkboxes - 1 means it is checked -->  <w:t>Informuar:PK</w:t><w:checkBox><w:sizeAuto/><w:default w:val="1"/></w:checkBox>   <w:t>SHME</w:t><w:checkBox><w:sizeAuto/><w:default w:val="0"/></w:checkBox>  <w:t>SHZSH</w:t><w:checkBox><w:sizeAuto/><w:default w:val="0"/></w:checkBox>  <w:t>,Shërbimet tjera</w:t><w:checkBox><w:sizeAuto/><w:default w:val="0"/></w:checkBox>    

In python I want to select values from that xml that is generated from a .docx document, that contain checkbox. I wrote code like this:

  WordNameSpace = '{http://schemas.openxmlformats.org/wordprocessingml/2006/main}'  para_tag = WordNameSpace + 'p'  text_tag = WordNameSpace + 't'  checkBox_tag = WordNameSpace + 'checkBox'  def get_docx_text(path):      document = zipfile.ZipFile(path)      xml_content = document.read('word/document.xml')      document.close()      tree = XML(xml_content)        paragraphs = []      for paragraph in tree.getiterator(checkBox_tag):          texts = [node.text for node in paragraph.getiterator(text_tag) if node.text]          if texts:              paragraphs.append(''.join(texts))        return paragraphs    results = get_docx_text('test.docx')    print results    

when i print results variable, result is only [] ? Why is this happening?
