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 -g
user$ vi valid-utf8-unclosed.html
<!DOCTYPE html>
<html>
<head>
<title>Das sind Umlaute: öäü</title>
</head>
<body>
<p
class="test"
>Das ist ein Test.<br />
<p>äöü
<ul>
<li>123
</ul>
</body>
</html>
user$ npm install html-validator-cli -g
user$ html-validator --file=valid-utf8-unclosed.html
Page is valid
or
user$ xmllint --html --noout valid-utf8-unclosed.html
The page is valid.
user$ unclosed-tag-finder valid-utf8-unclosed.html
valid-utf8-unclosed.html:7 (missing close tag: <p/>)
opening tag: <p
class="test"
>
valid-utf8-unclosed.html:10 (missing close tag: <p/>)
opening tag: <p>
valid-utf8-unclosed.html:12 (missing close tag: <li/>)
opening tag: <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, process.argv[2]);
if (unclosedTags.length == 0) {
return;
}
/* prints out missing close tag issues */
for (var i = 0; i < unclosedTags.length; i++) {
if (unclosedTags[i].hasNoCloseTag) {
console.info(unclosedTags[i].filename + ':' + unclosedTags[i].line + ' (missing close tag: <' + unclosedTags[i].name + '/>)');
console.info(unclosedTags[i].tag);
console.info('');
}
}
/* prints out missing open tag issues */
for (var i = 0; i < unclosedTags.length; i++) {
if (unclosedTags[i].hasNoOpenTag) {
console.info(unclosedTags[i].filename + ':' + unclosedTags[i].line + ' (missing open tag: <' + unclosedTags[i].name + '>)');
console.info(unclosedTags[i].tag);
console.info('');
}
}
});
user$ chmod 775 listUnclosedTags.js
Now check the file with the listUnclosedTags.js script:
user$ ./listUnclosedTags.js valid-utf8-unclosed.html
valid-utf8-unclosed.html:7 (missing close tag: <p/>)
opening tag: <p
class="test"
>
valid-utf8-unclosed.html:10 (missing close tag: <p/>)
opening tag: <p>
valid-utf8-unclosed.html:12 (missing close tag: <li/>)
opening tag: <li>
