hi there,

I have download a html page and try to replace all the href value and scr value to a certain domain, I have tried to use JQuery to do so, but SEO has index the source code in original href link, which is not good for search engine. Therefore, I have to do it at backend.

My Question is after i download the html page as a string, how can I replace all the href and scr value to my domain link, I was thinking about doing it by Linq, any idea will be helpful, Thanks.

What I have tried:

i try

XDocument doc = XDocument.parse(html);

，it has throw an exception, I think the tag format is not standardize.

As suggested, use the agility pack or use regex. If you google regex to replace href you'll find lots of examples. Don't use xml and you don't really need linq either.

You shouldn't use XML parsers for reading/writing HTML, because valid HTML is not necessarily valid XML. Use an actual HTML parser instead, for example the Html Agility Pack: Html Agility Pack | HAP[^]
