Driving browsers: #3 The states

Because sometimes reinventing the wheel is fun!

Time for the final part of my series on controlling a web browser. With code to load a browser, and the overarching State Machine to control it, this part finishes off with the code for some states to load a page and extract its markup. Plus a few conclusions...

Driving browsers: #2 The state machine

Because sometimes reinventing the wheel is fun!

Continuing from my previous post about firing up a browser in order to automate it, this post moves on to the overall pattern for how the browser can be controlled.

Driving browsers: #1 The Browser

Because sometimes reinventing the wheel is fun!

I bumped into an issue recently where I needed to write some code to scrape a bit of HTML. The usual .Net approach of using an HttpClient didn't work here - the web site in question made use of some client-side JavaScript to generate mark-up at runtime. So I needed a different approach to fetch the resulting HTML.

It had worked in the past, but the behaviour suddenly changed so that one field no longer got the "you can edit this" overlay in Experience Editor. It took me longer than it should have to work out why...

Thinking about the future of your markup

My work sometimes involves picking up projects that were started by other developers / agencies and making changes or enhancements. Sometimes the approaches used by the original developers can make these enhancements harder than they need to be. The HTML, CSS and Javascript of a recent project I worked on caused some issues that I thought were worth calling out to try and help developers do better work in the future.

The power of relative URLs

Quick (and not Sitecore specific) one today, as I've got a very busy week in the office and it's eating into my time for blog posts. To make a break from a few weeks of writing about navigation patterns, here's an idea about something I've found a surprising number of developers don't know about: "Protocol agnostic" or "Schemeless" URLs.
