@Deepak_Kumar_Patel
as mentioned by Adrian it is a RSS is XML
Kindly note the Webtable in the description element value
XML Processing we do with the help of the Deserialize XML Activity and then further with different methods / options e.g. LINQ for XML
When looking to the XML Details we do see that the XML is defining a document namespace which is to handle:

We do as described here:
So we do see:

the updated element is using the Atom namespace
In general we would loop over all items:
which would look like this:

for the demo we retrieves: title and updated (XML Namespace Demo)

For generic nested loop we can use the Elements method:

the table from the description we can again handle as XML (in some other scenarios we cannot)

And can apply the following:

Just for a quick retrieval RnD
So for the table generation we suggest:
- prepare the structure with a build Datatable Activity
- parse the xml and loop over the “item” elements the loop
- extract the values as introduced above
- populate and add the data row
Let us know when you need further help
Kindly note: The Demo snippets from the immediate panel will be adapted later to the implementation details. But as you can see we can quick prechecks our ideas can get support by the implementation work
