Hello,
I'm attempting to generate a random story using xml as the document,
and lxml as the parser. I want the document to be simplified before
processing it further, and am very close to accomplishing my goal.
Below is what I have so far. Any ideas on how to move forward?
The goal:
read and edit xml file, replacing random elements with randomly picked
content from within
Completed:
[x] read xml
[x] access first random tag
[x] pick random content within random item
[o] need to replace <random> tag with picked contents
xml sample:
<contents>Here is some content.</contents>
<random>
<item><contents>Here is some random content.</contents></item>
<item><contents>Here is some more random content.</contents></item>
</random>
<contents>Here is some content.</contents>
Python code:
from lxml import etree
from StringIO import StringIO
import random
theXml = "<contents>Here is some content.</
contents><random><item><contents>Here is some random content.</
contents></item><item><contents>Here is some more random content.</
contents></item></random><contents>Here is some content.</contents>"
f = StringIO(theXml)
tree = etree.parse(f)
r = tree.xpath('//random')
if len(r) > 0:
randInt = random.randInt(0,(len(r[0]) - 1))
randContents = r[0][randInt][0]
#replace parent random tag with picked content here
now that I have the contents tag randomly chosen, how do I delete the
parent <random> tag, and replace it to look like this:
final xml sample (goal):
<contents>Here is some content.</contents>
<contents>Here is some random content.</contents>
<contents>Here is some content.</contents>
Any idea on how to do this? So close! Thanks for the help in
advance. :)
