We are a group of veteran developers of internet technologies for over 20 years.
We frequently need the ability to modify an HTML file programmatically. Sometimes we wanted to preserve the spacing we had in the HTML, making it easy for us to see sections, troubleshoot, and see differences in before-and-after file comparisons. We couldn’t find a parser that preserved the whitespace when saving the HTML back to a file, so we used our 20 years of development experience and created one.
The parser met our needs, and we found that others needed it too. And others use it because they find it easier than the native HTML parser in PHP.
