I am trying to get all the texts not any attributes from HTML tags from a webpage using a search term and then trying to replace them with some other text. My regular expression $pattern1 = "/>([^<]*)</g" for this which gets the text from the tags. Though it isn't working here but it works here https://regex101.com/r/bExomf/2
Even if it works, I am having a problem integrating it with the search term like $pattern variable.
Here below is the code:
<?php
$file = 'j2-regex.html';
$searchfor = 'J2';
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
// escape special characters in the query
$pattern = preg_quote($searchfor, '/');
// finalise the regular expression, matching the whole line
$pattern = "/^.*$pattern.*\$/m";
$pattern1 = ">[^<]*</g";
// search, and store all matching occurences in $matches
if(preg_match_all($pattern, $contents, $matches)){
echo "Found matches:\n";
echo implode("\n", $matches[0]);
// Old string
$str_old = $searchfor;
// New string
$str_new = "J<sup>2</sup>";
// Replacing part of string
$final_str = str_ireplace($str_old,$str_new,$contents);
echo("Modified String : ");
echo($final_str);
}
else{
echo "No matches found";
}Maybe this helps a bit, if you really have to use regex.
<?php
$file = 'j2-regex.html';
$searchfor = 'J2';
$str_new = "J<sup>2</sup>";
$regex = "/<.*?>(*SKIP)(*FAIL)|" . $searchfor . "/";
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
$final_str = preg_replace($regex, $str_new, $contents);
echo("Modified String : ");
echo($final_str);
This is the working code:
<?php
$file = '../j2-regex.html';
$searchfor = $_POST['searchTerm'];
$replaceTerm = $_POST['replaceTerm'];
$regex = "~<.*?>(*SKIP)(*FAIL)|" . $searchfor . "~";
// the following line prevents the browser from parsing this as HTML.
header('Content-Type: text/plain');
// get the file contents, assuming the file to be readable (and exist)
$contents = file_get_contents($file);
if(preg_match_all($regex, $contents)){
echo $msg = "Matches Founded & File Replaced <a class='btn btn-success' target='_blank' href='j2-regex.html' style='float: right;bottom: 9px;position: relative;'>Visit Webpage</a>";
// // Replacing part of string
$final_str = preg_replace($regex, $replaceTerm, $contents);
// echo("Modified String : ");
// echo($final_str);
$myfile = fopen("../j2-regex.html", "w") or die("Unable to open file!");
fwrite($myfile, $final_str);
fclose($myfile);
// file_put_contents($file , $final_str, FILE_APPEND | LOCK_EX);
}
else{
echo $msg = "No Matches Founded <a class='btn btn-success' target='_blank' href='j2-regex.html' style='float: right;bottom: 9px;position: relative;'>Visit Webpage</a>";
}
?>
