Trouble reaching a text object in DOM with selenium (java)

Question

I have the below element in the page I am currently testing:

<li>
"At least 4 of the following rules must be satisfied:"
<br>
"Password should contain at least 1 upper latin characters (A-Z)"
<br>
"Password should contain at least 1 lower latin characters (a-z)"
"<br>
Password should contain at least 1 digits (0-9)"
<br>
"Password should contain at least 1 special characters: ! @ # $ % ^ & * ( ) _ + [ ] \ ; , . / { } | : " < > ?"
</li>

And I want to check that each of the lines of text is shown in the page. Each line is not an element but a text object, so after some searching I came to this post but the answer did not work as expected :( I used this chunk of code:

JavascriptExecutor javascriptExecutor = (JavascriptExecutor)driver;
String value = (String)javascriptExecutor.executeScript("document.evaluate(\"//*[@id='mainContainer']/form/div/div/div/div[2]/div/ul/li/text()[2]\", document, null, XPathResult.STRING_TYPE, null ).stringValue;");
System.out.println(value);

The xpath works and points to the correct object when checking in on Chrome, but the print command prints null. I know I cannot access the text node as a web element, so I wanted to pick every line separately and compare them with the relevant, expected, string (using softassert).

What am I doing wrong?

Thank you very much

You are not returning from the execute script

JavascriptExecutor javascriptExecutor = (JavascriptExecutor)driver;
String value = (String)javascriptExecutor.executeScript("return document.evaluate(\"//*[@id='mainContainer']/form/div/div/div/div[2]/div/ul/li/text()[2]\", document, null, XPathResult.STRING_TYPE, null ).stringValue;");
System.out.println(value);
