[reportlab-users] Problem parsing file

[shawn a]

Its failing to open the image because you are passing the string
representation of the image node(tags and all) to the Image object,
which is then trying to open it.

 I believe you are looking for something more like this

file = open("violation.tmpl", "r")
       tree = parse(file)
       elem = tree.getroot()
       for para in elem.findall('para'):
           contents.append(Paragraph(ElementTree.tostring(para),
paragraphStyle, None))
       for image in elem.findall('image'):
           contents.append(Image(image.data))

Ive replaced ElementTree.tostring(image)
with
image.data
this should return the text in BETWEEN the image tags.(your path)
