unclosed-tag-finder
Advanced tools
A library that finds unclosed html5 tags that are normally optional (via W3C check). These optional tags could be:
user$ npm install unclosed-tag-finder
user$ npm install unclosed-tag-finder -g
Create a W3C valid html5 file (but with some unclosed tags):
user$ vi w3cValid.html
<!DOCTYPE html>
<html>
<head>
<title>test</title>
</head>
<body>
<p>123
<p>456
<ul>
<li>123
</ul>
</body>
</html>
Install a W3C checker and check the file. You will see that the w3c checker above will accept the unclosed tags:
user$ npm install html-validator-cli -g
user$ html-validator --file=w3cValid.html
Page is valid
The page is valid. Now use the unclosed-tag-finder to find unclosed html5 tags:
user$ npm install unclosed-tag-finder
user$ vi listUnclosedTags.js
user$ unclosed-tag-finder w3cValid.html
The following tags don't seem to be closed
line 7: <p>
line 8: <p>
line 10: <li>
Although the html file is valid, we found some unclosed html5 tags.
#!/usr/bin/env node
/* load some libraries */
var unclosedTagFinder = require('unclosed-tag-finder');
var fs = require('fs');
var finder = new unclosedTagFinder.builder();
/* check command line arguments */
if (process.argv.length < 3) {
console.error('No file to validate was given. Abort..');
process.exit(1);
}
/* read given file */
fs.readFile(process.argv[2], 'utf-8', function(err, html) {
if (err) {
console.log(err);
process.exit(1);
return;
}
var unclosedTags = finder.getUnclosedTags(html);
if (unclosedTags.length == 0) {
console.info('Congratulations! No unclosed tags.');
} else {
if (unclosedTags.length == 1) {
console.info('The following tag doesn\'t seem to be closed');
} else {
console.info('The following tags don\'t seem to be closed');
}
for (var i = 0; i < unclosedTags.length; i++) {
console.info('line ' + unclosedTags[i].line + ': ' + unclosedTags[i].full);
}
}
});
user$ chmod 775 listUnclosedTags.js
Now check the file with the listUnclosedTags.js script:
user$ ./listUnclosedTags.js w3cValid.html
The following tags don't seem to be closed
line 7: <p>
line 8: <p>
line 10: <li>
