Hi,

We're trying to fetch data from an html page where content is distributed under multiple tabs. We're using "Send HTTP Request" smart service for this purpose. Content that we receive as an output of this smart service consists of data from first tab only.

Is there a better way to get entire page content (from all tabs) and then extract data out of it using xpath ?

Thanks in advance,
Sandeep Kumar

It depends on how the website is built. If switching between tabs is done using javascript and the tabs are not accessible by some URL parameters it will get difficult.

Thanks @stefanh791

Attached is the response body that we received as "Send HTTP Request" service output for url: ted.europa.eu/udl

This page has two tabs: Original Language, Data

But we're getting details of 1st tab only.

I see. The tabs are rendered dynamically and only the content is delivered for the selected tab. So to get both you would have to do two calls.

We're using following code to extract title of active tab for which content is displayed in response body.

xpathsnippet(pv!responseBodyText, "//[id='tabs']//ul/li[@class='activated']/div/a/text()")

But unfortunately it throws an error saying "Error parsing xml..."

The problem is that HTML does not have to be valid XML to be rendered by a browser, so many websites use broken HTML which can not be parsed using xPath.

I would not recommend to scrape content from a website using Appian.
