Tidying Html5 Output Indentation In Php
My web application produces HTML5 output as a concatenation of a variable number of views. The end result is a mess of indentation:
Solution 1:
If you want to obscure the origin of individual views, I suggest you to minify the HTML. This will have the added benefit of reducing the document size.
As for making the HTML output easier to follow, browsers come with debug utilities that parse and render out DOM tree in an indented format, e.g. https://trac.webkit.org/wiki/WebInspector, http://getfirebug.com/.
Solution 2:
The closest to what you are looking for in the PHP land is Dindent, https://github.com/gajus/dindent. Dindent is a HTML beautifier that uses regular expressions to indent the markup. This is different from Tidy, that acts as a DOM parser.
From the documentation:
There is a good reason not to use regular expression to parse HTML. However, DOM parser will rebuild the whole HTML document. It will add missing tags, close open block tags, or remove anything that's not a valid HTML. This is what Tidy does, DOM, etc. This behavior is undesirable when debugging HTML output. Regex based parser will not rebuild the document. Dindent will only add indentation, without otherwise affecting the markup.
Dindent sole purpose is to indent the HTML markup. It allows to configure what elements to treat as inline and what elements to treat as block.
