How to regex scrape HTML and ignore whitespace and newlines in code?

How to regex scrape HTML and ignore whitespace and newlines in code?

seems to work fine Needless to caution you that you're playing with fire by trying to use regex with HTML code. Anyway to answer your question you can use this regex:
code :
$regex='#^<td class="things">\s*<div class="stuff">\s*<p>(.*)</p>\s*</div>\s*</td>#si';
$html = <<< EOF
<td class="things">
    <div class="stuff">
        <p>I need to capture this text.</p>
    </div>
</td>
EOF;
$doc = new DOMDocument();
libxml_use_internal_errors(true);
$doc->loadHTML($html); // loads your html
$xpath = new DOMXPath($doc);
$nodelist = $xpath->query("//td[@class='things']/div[@class='stuff']/p");
for($i=0; $i < $nodelist->length; $i++) {
    $node = $nodelist->item($i);
    $val = $node->nodeValue;
    echo "$val\n"; // prints: I need to capture this text.
}

How to convert html code to a string that replaces the newlines with \n and tabs with \t

it fixes the issue Is there an easy way to convert HTML code, that is structured in a certain way, to a single string (that can then be used in a Javascript variable). The new lines and tabs in the html code need to be converted to \n and \t so that the formatting can stay in tact.
code :
    function format(data) {
        var returnStr = "";
        var lines = data.split("\n");
        var block = [];
        for (var i = 0; i < lines.length; i++) {
            block = lines[i].split('\t');
            for (var j = 0; j < block.length; j++) {
                returnStr += block[j];
                if (block.length>1) {
                    returnStr +=  "\\t";
                }
            };
            returnStr +=  "\\n";
        };
        return returnStr;
    }

this one helps. Your question appears to be "why doesn't the reverse of the original approach [of converting spaces to newlines] work?".
In sed, the newline is more of a record separator than part of the line. Consider that $, the null at the end of the pattern space, comes after the last character of the line, and is not a newline of every line.
code :
printf 'foo\nbar\nbaz\n' | sed -n '1h;2,$H;${;x;s/\n/ /gp;}'

To fix this issue Yes, Intellij has code style option called 'Keep line breaks in text' for HTML. Disable that option, and then reformat code.

With these it helps In LaTex you need to have a double-newline in order to start a new line (if you are not using some other command that does that for you). Since you are using 'asis', your output is directly interpreted as LaTex code.
