Question

I’m trying to get rid of all data- attributes in a document. If my document looks like

<div id="person" data-name="John Smith" data-age="32" data-location="UK">...</div>

I want to strip out the data to just leave

<div id="person">...</div>

I’ve tried a lot of combinations, and can a least get to things like data-name with

doc.xpath('//@data-name')

but sometimes, there will be more data-? properties, and I’d like to avoid manually adding them all. This SO answer is close, but it’s not returning anything for me when I try

doc.xpath("//*[@*[contains(., 'data-')]]")

Answer 1

To select all attributes whose name starts with data-:

//@*[starts-with(name(), 'data-')]
