Extract text from tag content using regular expression

[snippsat]

In your 'a[href^⁼"/Cybersecurity"]' there is a Unicode ⁼ the normal is =.
This is not the best way for this anyway,as it find all Cybersecurity links and return a list then have to clean up some more.

Could it possible to search using keyword 3319988417, which is ISBN for this book.

Think i did answer this in your other Thread post #6.
