Hi all,
Here is a version that should not fail when encountering punctuation.
```PHP
#!/usr/bin/env php
<?php
//---
function jj_ucwords($string) {
return preg_replace_callback('/\b(\w)/', function ($matches) {
return strtoupper($matches[0]); }, $string);
}
//---
function capitalize_skipping_inner_tags($string) {
$array = preg_split('/(<[^>]+?>)/iusx', $string, -1,
PREG_SPLIT_DELIM_CAPTURE);
$m = count($array);
$i = 0;
while($i < $m) {
if (strpos($array[$i], '<') === 0) {
$i++;
} else {
$array[$i] = jj_ucwords(strtolower($array[$i]));
}
$i++;
}
return implode($array);
}
//---
$input = file_get_contents('php://stdin');
$split_pattern = '/(<a[^>]+?>|<\/a>)/iusx';
$array = preg_split($split_pattern, $input, -1,
PREG_SPLIT_DELIM_CAPTURE);
$m = count($array) - 1 ;
$i = 0;
while($i < $m) {
if (stripos($array[$i], '<a') === 0) {
$i++;
$array[$i] = capitalize_skipping_inner_tags($array[$i]);
}
$i++;
}
$output = implode($array);
file_put_contents('php://stdout', $output);
exit(0);
//---
```
And another version using NodeJS:
```JavaScript
#!/usr/bin/env node
process.stdin.resume();
process.stdin.setEncoding('utf8');
// Capitalize words but leave inner tags untouched.
function capitalize(text) {
const splits = text.split(/(<[^>]+?>)/i);
const n = splits.length;
let i = 0;
while (i < n) {
if (!splits[i].startsWith('<')) {
splits[i] = splits[i].toLowerCase().replace(/\w\S*/g, (w)
=> (w.replace(/^\w/, (c) => c.toUpperCase())));
}
i++
}
return splits.join('');
}
process.stdin.on('data', function(text) {
const splits = text.split(/(<a[^>]+?>|<\/a>)/i);
const n = splits.length - 1; // Last item is itself an closing
anchor tag of not inside an anchor. Hence, no need to capitalize it.
let i = 0;
while (i < n) {
if (splits[i].toLowerCase().startsWith('<a')) {
i++;
splits[i] = capitalize(splits[i]);
}
i++
}
process.stdout.write(splits.join(''));
})
```
BTW does anyone know how to add code highlighting to this posts ?
Best regards,
Jean Jourdain
