Is is possible to update just the attribute value but leave the rest html unchanged? #551

pakhmedzianov commented 5 months ago

I need to update attribute value but preserve the rest html exactly like it was at the input. I'm configuring my document like:

        var htmlDoc = new HtmlDocument();
        htmlDoc.OptionFixNestedTags = false;
        htmlDoc.OptionCheckSyntax = false;
        htmlDoc.OptionAutoCloseOnEnd = false;

But unfortunately HtmlAgilityPack, automatically modifies html. And I could not find the way to properly disable it. Please help/advise.

Hello @pakhmedzianov ,

Unfortunately, HAP output HTML its own way. We cannot simply change only 1 attribute and have the same exact HTML outputted beside this one. This is currently not feasible through HAP.

Best Regards,

Jon
