Cheerio: Explain \\: escaping colon for xml namespace pseudo

[dandv]

While attempting to parse an RSS feed, I got the SyntaxError: unmatched pseudo-class :origlink error. Looking through the issues, I only found references to jQuery pseudo-classes.

For XML parsing, it might help to mention escaping the : with a double backslash. On the other hand, that's a standard CSS selector feature, so maybe the text of this issue will be enough SEO to help others who run into the same error.

As you already said, it's a basic CSS feature. Having an issue to refer to is useful, but it hasn't to be open :)

Thanks, I had exactly this issue!

Me too! Hooray for SEO! :smile:

In case anyone stumbles upon this with the intention to use attr, escaping is not necessary (nor possible) in that use case.

lol just ended up back here a year and a half later. It might be nice if this error message were slightly different when xmlMode:true to give a hint at the quick fix.
