xSkrape.APIWrapper.InProc.Sample

xSkrape provides data parsing for structured, semi and non-structured data sources. Extract tabular and discrete data from sources with minimal coding. Interact with HTML, JSON, XML, CSV, Excel and other sources over http/https using simple directives. Pull data from Google Docs, shape data from web API's, merge data over multiple requests, and more.

This assembly can be included directly in your .NET Framework projects (available on NuGet). Most functionality requires a client key that can be obtained by creating a free account at xskrape.com, confirming your email address, and visiting the Queries page under My Account. Note that you receive free credits each month. The in-proc library charges 200 credits per machine for the first 30 day period, then 500 credits every 30 days thereafter. More details can be found here: https://www.xskrape.com/home/faq. Examples of usage can be found here: https://github.com/codexguy/xSkrape.APIWrapper.InProc.Sample/blob/master/InProcExamples.cs.

One example is for pulling tabular data from an HTML source, in this case a spreadsheet published in Google Docs:

var result = await xSkrapeInProc.GetDataTable(CLIENT_KEY, "https://docs.google.com/spreadsheets/d/1r_gYGu8nawdIk7wpUrbL1evCqE0eygC-TZwVD9ViS-o/edit?usp=sharing", "columnname=Name");

Of note, one line of code is all that's needed here to fully express where the data is, and a hint is provided about what it looks like (a column titled "Name"). As a second example:

var url = "http://www.ndbc.noaa.gov/data/latest_obs/46042.rss";
Dictionary queries = new Dictionary()
{
  { "name", "firstelement=title" },
  { "windspeed", @"numberfollowsnear=Wind\ Speed" },
  { "winddir", @"followinginnertext=Wind\ Direction" },
  { "pubdate", "xpath=/rss[1]/channel[1]/pubDate[1]/text()" }
};
var result = await xSkrapeInProc.GetMultiple(CLIENT_KEY, url, queries);

Here we're pulling four discrete values from a single page source using four different approaches. The last approach of using an xpath expression works for virtually all pages: even ill-formed HTML. However, the simplest approaches are to use simple matching terms like "numberfollowsnear" - very easy to understand and use. We even have a tool that can make suggestions about how to extract values and tables - see https://www.xskrape.com/Home/XSPageExplorer.

The in-proc library can access local files and UNC files (the REST library cannot do this). This introduces solutions such as reading files from landing directories, log files, and more.
