python - Quick way to extract CSS style attributes from html elements -


for machine learning purposes, have html page input, extract style attributes of dom elements. so, here preliminary code:

from selenium import webdriver  start = time.time() driver = webdriver.phantomjs() driver.get('example page') elements = driver.find_elements(by.xpath, "//*[not(child::*)]") #select leaf nodes l = {} css_properties=("line-height", "text-align","font-size", "font-style")  in elements:     if i.text:         #print time.time() - end_dl         if i.text not in l:             l[i.text] = {}         el in css_properties:             l[i.text][el] = str(i.value_of_css_property(el))             l[i.text]["text_length"] = len(i.text)

the problem code taking long parse features (~8s). can think in faster way this?

are sure it's parsing step that's taking long?

if so, here few options...

  1. try beautifulsoup4 parsing dom.
  2. deploy on cloud server faster hardware. use amazon ec2 or digitalocean charges hour.
  3. deploy on distributed system.

c# - Send Image in Json : 400 Bad request -

from android trying send image class of data, iis webservice. (c#) the problem 400 bad request . the image being encoded base64 . , placed json rest of class elements. my guess base64 not valid inside json. server not understand it. if set string "" , post accepted fine. so question is, how make base64 valid within json array? ( tried url.encode no success). or how should send image android webservice? gson gson = new gson(); string json = gson.tojson(record); // record has param { string base64photo } how big image? i'm pretty sure surpassing iis json size limit (default 4 mb). check http://geekswithblogs.net/frankw/archive/2008/08/05/how-to-configure-maxjsonlength-in-asp.net-ajax-applications.aspx or http://www.webtrenches.com/post.cfm/iis7-file-upload-size-limits good luck!
