Out of memory

I don't know why, but it crashes when I run it. The version I am using is 0.0.4, the python version is 2.7.
Below is my code
```
  with open(xmlPath, 'rb') as f:
                ap = axmlprinter.AXMLPrinter(f.read())
                dom = xml.dom.minidom.parseString(ap.getBuff()).toxml()
                print dom
```
