Grab all text (including new lines) with Regex – Artificial Intelligence

I’m trying to figure out how to grab all the text after [text](URL), but I’m having difficulty including the entire text after it because of the new lines (nn). I’m currently trying variations of (?<=.)nn)(.*n+), but it’s only including the next paragraph.

Here’s what the text looks like:

How should we think about artificial general intelligence (AGI), and the risks it might pose? What constraints exist on technical solutions to the problem of aligning superhuman AI systems with human intentions? In this episode, I talk to Richard Ngo about his report analyzing AGI safety from first principles, and recent conversations he had with Eliezer Yudkowsky about the difficulty of AI alignment.

**Daniel Filan:**
Hello, everybody. Today, I'll be speaking with Richard Ngo. Richard is a researcher at OpenAI, where he works on AI governance and forecasting. He also was a research engineer at DeepMind, and designed the course ["AGI Safety Fundamentals"](https://www.eacambridge.org/agi-safety-fundamentals). We'll be discussing his report, [AGI Safety from First Principles](https://www.alignmentforum.org/s/mzgtmmTKKn5MuCzFJ), as well as his [debate with Eliezer Yudkowsky](https://www.alignmentforum.org/s/n945eovrA3oDueqtq) about the difficulty of AI alignment. For links to what we're discussing, you can check the description of this episode, and you can read the transcripts at [axrp.net](https://axrp.net/). Well, Richard, welcome to the show.

**Richard Ngo:**
Thanks so much for having me.

Thanks for the help!

    I've decided to opt for the following approach:

    end = re.search('[(Google Podcasts link)]((.+))nn)', text).end()
text = text[end:]

    So I just look for the text I want to start the text afterwards, and just use the .end() to slice the text string where I want to.

    Assuming you can afford to read in this entire text into a string variable, you may use re.search here:

    s = re.search(r'[.*?](https?://.*?)s+(.*)', text, flags=re.S)
print(s.group(1)))

    This prints the text you seem to want:

    Note that we are doing this regex find in dot all mode, so that .* will match across newlines.

    As there seems to be 1 occurrence, you could also use split with the pattern:

    (?m)^s*[[^][]*](https?://[^s()]*)s*

    Explanation

    • (?m) Enable multiline
    • ^ Start of string
    • s* Match option whitespace character
    • [[^][]*] Match from [...]
    • (https?://[^s()]*) Match an url between parenthesis
    • s* Match trailing whitespace characters

    See the matches at the regex101 demo

    Example

    result = re.split(r"(?m)^s*[[^][]*](https?://[^s()]*)s*", text)
print(result[1])

    Or more specific

    result = re.split(r"(?m)^s*[Google Podcasts link](https?://[^s()]*)s*", text)
print(result[1])

    See a Python demo.
