re.match doesn't pick up on txt file format

around this issue "^.+.\txt$" is an incorrect pattern for match .txt files you can use the following regex :
code :
r'^\w+\.txt$'
r'^[a-zA-Z]+\.txt$'
re.match (r'^\w+\.txt$',file)
file.endswith('.txt')

cts:uri-match to pick a particular format

Hope that helps Unfortunately, cts:uri-match takes a wildcard pattern, not a regex. The closest you can get is with a pattern like "/documents/*.xml". It could trim down the number of results drastically already though, depending on your dataset. You can then filter out false positives with an additional predicate with fn:matches. Something like:
code :
cts:uri-match('/documents/*.xml')[fn:matches(., '^/documents/\d+\.xml$')]

Any of those help I want to match a pattern and pick next line completely once that pattern matches. I have file with below input in file1: , Answer 1:
code :
egrep -A 1 "Envvi|Department" example_1.txt | awk -F: -v ORS="-" '/Value/ {print tolower($2)}' | sed -e 's/[" ]//g' -e 's/-$/\n/' -e 's/^/aws_/'
{
    "Key": "Envvi",
    "Value": "model"
 },

    "Key": "Department",
    "Value": "Sys"
 }

I hope this helps you . Your problem is due to how the "contains" block works. It is natural to assume that it would compare the value you give it to each value in the list, and would evaluate to "true" if there's a match and "false" if there's not. But unfortunately, that's not what it does. Instead, it treats the list as a single string formed by concatenating all of the elements in the list (separating each element with a space), and then checks to see if the thing you asked was contained by the list is in that string.
You can see this in action if you run this snippet:

To fix this issue You may want to use a better selector for the input elements. You can use input[id^='points'] for example. This will look for input elements with a the id that starts with points.
Consider the following example:
code :
var results = $("input[id^='points']");
var points = 'Enter a valid point.';
var regex = '/^[A-Za-z!@#></!?\$%\^\&*\)\(+=._-]+$/g';
results.each(function(i, el) {
  if ($(el).val().match(regex)) {
    console.log("Match on #" + $(el).attr("id"));
    $(el).next('span').html('');
    $("<span>", {
      class: "errTextboxClass"
    }).css("color", "#e03b3b;").html(points).insertAfter($(el));
    $(el).focus();
  }
});
^[\D]+$
$(function() {
  $("input[id^='points']").keypress(function(e) {
    console.log(e.which);
    if (e.which !== 46 && (e.which < 48 || e.which > 57)) {
      e.preventDefault();
    }
  });
});
label {
  width: 80px;
  display: inline-block;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div>
  <label>Points 1</label> <input id="points1" type="text">
</div>
<div>
  <label>Points 2</label> <input id="points2" type="text">
</div>
<div>
  <label>Name</label> <input id="name1" type="text">
</div>

wish of those help If you want to find the fifth line that matches and print that line and all subsequent matching lines:
code :
awk '/new mining work/ && ++count >= 5 {print $2,$3}' /home/ubuntu/geth-general/node1.txt
awk '/new mining work/ && ++count >= 5 && count <=23 {print $2,$3}' /home/ubuntu/geth-general/node1.txt
