Null Text Node issue with xml.dom.minidom in Python
===

Environment: Python 2.6.5, Eclipse SDK 3.7.1, Pydev 2.3

I am trying to parse and change values in XML data in Python using xml.dom.minidom and I'm having an issue with blank text nodes.  

When I parse an XML file into a DOM object and then convert it back to a string using toxml(), the closing "Description" tags get messed up after all the blank text nodes.  

Does anyone know the problem is?


**Contents of issue.py**

    from xml.dom import minidom  
    xml_dom_object = minidom.parse('news_shows.xml')  
    main_node = xml_dom_object.getElementsByTagName('NewsShows')[0]  
    xml_string = main_node.toxml()  
    print xml_string  


**Contents of news_shows.xml** (notice the two blank Text nodes)**:**

    <NewsShows Planet="Earth" Language="English" Year="2012">
    <NewsShow ShowName="The_Young_Turks">
     <Description Detail="Best_show_of_all_time_according_to_many">True</Description>
     <Description Detail="The_only_source_of_truth"></Description>
     <Description Detail="Three_hours_of_truth_per_day">True</Description>
    </NewsShow>

**Output of the script** (notice the 2 "Description" tags that are messed up)**:**
