First of all, I'm new to working with Python, especially Selenium. So I connected to a page with the webdriver and also already grabbed the InnerHTML I need. Here's my problem, InnerHTML is a "list" and I only want to output one value. It looks something like this:
<html>
<body>
<pre style="example" xpath="1">
"amount": 12{
"value" : 3
},
</pre>
</body>
</html>
^It's just for illustration, because the actual thing is much longer. InnerHTML looks like this:
"amount": 12{
"value" : 3
},
^This is where I am now. I can't specify a line because the page is not static. How do I make python find "value" from a variable in InnerHTML ? Please note that there is a colon after "value"!
Thank you very much in advance!
I suggest using regular expression to find the value. I assume that you only need the number part, so here's the code:
innerHTML = '''
"amount": 12{
"value" : 3
},"value":4
'value': 5
'''
import re
regex = re.compile(r'''("|')value("|')\s*:\s*(?P<number>\d+)''')
startpos = 0
m = None
while 1:
m = regex.search(innerHTML, startpos)
if m is None: break
print(m.group("number"))
startpos = m.start() + 1
# output:
# 3
# 4
# 5
This will print out all the value numbers found, as strings. You can convert them to integers afterwards, for example.
NOTE: My code also accounts for the case value is surrounded by single quotes ' rather than double quotes ". This is for your convenience; if not, you can change the appropriate line above to:
regex = re.compile(r'''"value"\s*:\s*(?P<number>\d+)''')
In that case, the output would not include the value 5.
