Learning RPA with UIPath. Happily extracting onscreen data from a website, processing it, using it, etc.
However, there's information in the page that isn't visible, but is in the source, eg, open graph meta tags:
<meta property="og:image" content="https://example.com/foo.jpg" />
What options are open to me to extract this with UIPath? I gather there's an ExtractMetaData flag from ExtractData but I've yet to find a useful tutorial that I can follow at this stage :/
You can try and use Data Scraping option by selecting the respected option from the Wizards Tab as show below:
Now you need to indicate on the screen the area of data that you need to scrape, like:
Structure data in form of table
Specific element on the web page
Or the whole window
Data scraping activity generates a container (Attach Browser or Attach Window) with a selector for the top-level window and an Extract Structured Data activity with a partial selector as per images below:
So all you need to do is place your XML tag as Input under ExtractMetadata field as per image below:
Hope these information will be useful.

I'm trying to create a clone of getpocket.com for learning. On that app, every saved link gets converted into a markdown; and it seems like the it's a filtered content with only the page title and body without headers, footers, etc.
I could get the page's title using puppeteer api thru different means:
using page.title()
or get the page's opengraph "og:title"
But how do i get like the summarized version containing only the main content of the page.
Note that i don't know beforehand the "css class" of the main content since i'm planning on just entering a url in a textbox and scrape that site from there.
I have found what i've needed for this scenario.
I used the Readability.js library for making webpages readable by removing some certain html tags. Here's the library.
This library is what mozilla uses behind the scenes when rendering their reader view
I have used python scrapy to extract data from a website. Now i am able to scrape most of the details of a site using scrapy. But my main problem is that iam not able to extract all the reviews of products from the site. I am only able to extract the top 4 reviews which they display on the page and for getting other reviews i have to go to a pop up window which has all the reviews. I looked for 'href' for the popup window but im not able to find it. This is the link that i tried to scrape. The reviews and ratings are at the bottom of the page: https://www.coursera.org/learn/big-data-introduction
Can any one help me by explaining how to extract the reviews from this popup window. Another think to note is that there is infinite scrolling for the pop up.
Thanks in advance.
Scrapy, unlike tools like Selenium and PhantomJS, does not drive a full web browser in the background. You cannot just click a button.
You need to understand what the button does (e.g. does it simply submit a form? Does it do something with JavaScript? Etc.) and reproduce the functionality in your own code.
For example, you might need to read the content of a script element, apply regular expressions to it to pull a URL from a string literal, then make a new HTTP request to that URL, the pell the data you want from the new DOM.
... and then repeat for the next “page” of the infinite scroll.
How do you get rid of or replace the Microsoft Azure Media Services logo overlay (water mark) that is put onto dynamic packaged video? The following link shows the topic area:
https://azure.microsoft.com/en-us/documentation/articles/media-services-dynamic-packaging-overview/
My html contains embedded code taken from http://amsplayer.azurewebsites.net/azuremediaplayer.html
It seems that you are attempting to use the iframe embed code on the "get embed code" section of the player. Please note that this is currently under development, as it is listed on the site: "this embed code is for demo purposes only. Do not use in production."
For your player needs in production, especially if you want to use the large amounts of API's available, you should create your own player page following the instructions in the documentation and by using the samples provided.
Specifically for the question regarding the logo, there is an API available to remove to logo and can be found in the logo option section of the documentation. This is the correct way to remove to logo using the APIs provided.
It might be helpful to post some of the HTML that you are using when you say "My html contains embedded code taken from..."
It looks like the code on that page has the following div:
<div class="amp-logo" style="opacity: 0.5;"></div>
This appears to be what is placing the logo on the page you reference. Not know what HTML is actually in your page, I don't know if this is the HTML they are generating for you as embedded or whether you cut and paste the HTML from the given page.
You may be able to remove it from your HTML. If not, try creating a style that overrides the amp-logo class.
I'm trying to create a CSS documentation library in Orchard. I want to save a description, CSS snippet and HTML snippet against each content type. The first view would show the description and CSS and HTML code written out. The second view would show a preview of what the CSS and HTML look like rendered.
cssdocumentation.com/content/item1
cssdocumentation.com/content/item1/live-preview
I've created the content type and the first view. But I'm not sure how to create the second view. I can see if I can create the alternative URL I can use the Url Alternates module to create an overriding .cshtml
To create an alternative URL I've looked at the autoroute module but this only allows you to adapt a single URL (unless I'm missing something?) and I've looked at Alias UI but this forces me to manually create an alternative URL everytime I create a content item.
Is this possible in Orchard without writting too much C#? (I'm a frontend developer so I only dabble in the behind the scenes stuff)
Thanks for any help
Best solution is to do this within your own module. But as a secondary option instead of having a second page, combine this content with your first page and hide it with CSS. When the user clicks a button to navigate to the next step render the CSS/HTML result on the same page. You can do this in many ways, here are a few ideas:
Render the CSS/HTML result out straight away on the same page but hide it. Show it when the user clicks a button
using jQuery to render the result on the client side. More dynamic if you allow editing of the HTML and CSS.
Redirecting the user to the same page with specific url parameters which you can pick up in your alternate to modify the output.
I'm a coldfusion developer working on a reporting application to display information from a CFSTOREDPROC process. I've been able to get the data from my query to display correctly in a CFGRID, and I'm really happy with the display of the data. The grid saves a lot of time because it avoids using the CFOUTPUT tag and formatting the data in HTML for hundreds of reports.
All I would like to do is add a simple Disk Icon somewhere on the datagrid control that would save the contents of the datagrid and export it into an XLSX(2010) file that an end user could then manipulate in a spreadsheet program. This is important because the data needs to have a 'snapshot' at certain times of year saved.
Solutions Tried:
I looked into having a link from the report options page that would fire into a report_xls.cfm page but designing a page that catches all of the report options a second time seems dumb and would add thousands of CFM's to the website.
CFSPREADSHEET seems not to work for a variety of reasons. One is that the server seems to constantly fight me with the 'write' function in this tag. Another is that I don't know how to make the javascript work for this button to get the output that I want.
I also looked into doing this as a Javascript button that would fire based on the data entered. Although the data from a CFSTOREDPROC will display correctly if I use a CFOUTPUT block, CFGRID seems to have a hard time with all output styles except HTML. This has caused some difficulty with these solutions because the application doesn't spit out a neat HTML table but instead sends a javascript page section.
Raymond Camden's blog contains an entry Exporting from CFGRID that we used in our project.
The example in the article exports to PDF, but it is rather simple to modify the download.cfm file to export to Excel files as well:
You modify the file to generate the <table>...</table> HTML from his example in a <cfsavecontent variable="exportList"> tag, so that the #exportList# variable contains the table that will be shown in the spreadsheet.
Next we have a URL parameter mode that determines whether it is exported to PDF or Excel.
So the end of our download.cfm looks like the following:
<cfif url.mode EQ "PDF">
<cfheader name="Content-Disposition" value="inline; filename=report.pdf">
<cfdocument format="pdf" orientation="landscape">
<cfoutput>#exportList#</cfoutput>
</cfdocument>
<cfelse>
<cfcontent type="application/vnd.ms-excel">
<cfheader name="Content-Disposition" value="report.xls">
<cfoutput>#exportList#</cfoutput>
</cfif>
