Selenium - get all children divs but not grandchildren
python,html,parsing,selenium,selenium-webdriver
Here is a way to find the direct div children of the div with class name "main_div": driver.find_elements_by_xpath('//div[@class="main_div"]/div') The key here is the use of a single slash which would make the search inside the "main_div" non-recursive finding only direct div children. Or, with a CSS selector: driver.find_elements_by_css_selector("div.main_div > div")...

Whats the simplest way when writing & reading a 2D-boolean-Array to a CSV File?
Use uniVocity-parsers to write/read your booleans. public static void main(String ... args){ CsvWriterSettings writerSettings = new CsvWriterSettings(); ObjectRowWriterProcessor writerProcessor = new ObjectRowWriterProcessor(); // handles rows of objects and conversions to String. writerProcessor.convertAll(Conversions.toBoolean("T", "F")); // will write "T" and "F" instead of "true" and "false" writerSettings.setRowWriterProcessor(writerProcessor); CsvWriter writer = new CsvWriter(writerSettings);...
How to translate parts of source program to library calls without writing a full parser?
There's a lot of parsing wrapper generators out there, chief among these SWIG (which is awesome, and horrible at the same time). If you can't use SWIG or something like existing parsers: I'd completely avoid changing the original code -- the C functions must be externally visible, anyway, so it's...

How to parse Selenium driver elements?

find_elements_by_css_selector() would return you a list of WebElement instances. Each web element has a number of methods and attributes available. For example, to get a inner text of the element, use .text: for element in driver.find_elements_by_css_selector("div.flightbox"): print(element.text) You can also make a context-specific search to find other elements inside the...

Parse.Cloud.httpRequest not returning response
Parse.Cloud.httpRequest() is an asynchronous function call. It doesn't block the thread, so your code keeps running to status.success("Saved successfully."); before you get the result from httpRequest(). Parse.Cloud.httpRequest() returns a Promise now, so you can simply chain them together. Parse.Cloud.job("Loader", function(request, status) { var xmlreader = require('cloud/xmlreader.js'); var moment = require('cloud/moment.js');...
