Like normal scraping action, add scrape page and capture content actions, then change extract type to regular expression, input the re string to the control. For scrape the email address.īecause FMiner will run the re string for the target html code, you should keep target xpath to /html for the whole page. FMiner run the re string with javscript fuction RegExp.match with parameter " igm", and you must make sure the string is correct. Normally you can select all targets with group select. For complex selections, you can input XPath manually, here's a basic tutorial of XPath: I can't select all the contents I want to scrape.įMiner locate the targets with XPath and Postion, see select target. You can also create more scrap page actions for the different block groups if you really can't select all the contents you need in a selection. How to see the html code of a page?įMiner has a tool of web inspector, when disable record and right click the page select option "Inspect" in the menu, it will show. Stay connected as I am going to post more code templates that will make your web scraping life easy and manipulate data on fly.If you want to wait some time for ajax to update the page, you should add a wait time node after it.įrom 8.00 version, FMiner add a new action of "scroll down" , you can add this action directly.įor some pages without searching button, must input Enter key to get result, "fill" action may not work, you can use "runjs" code and write some code like this to fire the event: evt = document.createEvent("KeyboardEvent") Įvt.initKeyboardEvent("keyup", true, true, window, false, false, false, false, 13, 0)ĭocument.getElementById("suggestBo圎Q").dispatchEvent(evt) It's helpful to write XPath of targets manually.Īdd an action “run javascript in browser”, and input code: window.scrollBy(0,20000) You can see the page code and DOM tree structure on it. '''Strip HTML will remove all html tags of a column in data table.ĬolNew = ''Ĭleantext = re.sub(cleanr,'', row) Below is the code of template for stripping html: I have created one template which I use to remove HTML code that comes while scraping badly organized HTML pages. Templates are stored at following path so you can create your own template with customized code. In many web scraping projects I found this template code very handy for cleaning data and making life easy. Step 4: Now you can see the code of that template, now you can click on execute icon and script will start running, based on number of records it will take time to finish execution. Step 3: Now the window will appear for configuration that will ask you to choose the table and column under that table on which you want to execute the code. Step 2: One popup will appear, you need to click on “Templates” icon and choose the template you want to execute and then click on Ok. Step 1: Click on second icon from right that says “Run Code” under the Data section Below are the steps how you can execute template python code on scraped data. This template comes with Fminer and few other template like “merge_tables_with_same_columns”. Remove the blank of data in the head and the tail.ĬolName = '' '''Strip all data of a column in data table Assume if you get white space in scraped data then you can easily trim this left and right spaces by just executing “strip_column” template, see the code of that template below. While Run Code Templates are the saved python code snippets that you can run on the data tables after scraping completes. The Run Code Action you can use inside the data scraping flow and python code get executed when scraper start running. In this post I am going to introduce one of the interesting feature of fminer which is Run Code Template that is recently added to Fminer, this feature is similar to “Fminer Run Code” action but it’s different in a way you can use it. Run Code Template – New Feature Added to Fminer Web Scraping Toolįminer is one of the powerful web scraping software, I already given brief of all the Fminer features in previous post.
