How to extract information from the following text?

Question

I'm trying to extract title, description & address from text of different websites. I'm currently doing some web crawling which extracts the information stated above. However, I am having trouble coming up with a regular expression that matches to the expected text output that I want below.

Can I know how can I improve my regular expression and embed the suggested set of rules to meet and extract the information above?

My Regex:

(^.+\n)(^.+\n)?(^\d+.*\d{6})

Set of rules to embed:

First line (title)
    - can contain any alphabets and numbers
    - should not contain dot(.)
Second line (description or additonal information)
    - can contain any alphabets and numbers
    - should contain dot(.)
    - second line can be empty
    - if its empty then extract the first line which is the title
Third line (address)
    - address extraction

Answer 1

One option is to match words using \\w and repeat the first capturing group to get the value of the last iteration as the title.

^(\w+(?: \w+)*\r?\n)*(?:(?![^.\r\n]*\.|.*\d{6}).*\r?\n)*(?:([^\r\n.]*\..*(?:\r?\n(?!.* \d{6}).*)*)\r?\n)?(.* \d{6}(?:\r?\n(?![A-Z]).*)*)$
