The address strings, not the physical image. <img src="blabalbalbal.jpeg" /> I need to pull the source of each img tag. I just want to get a feel for the library and what it can offer.

HTML Agility pack - parsing tables

由 自闭症网瘾萝莉.ら 提交于 2019-11-26 12:42:13

Last, the OuterHtml is like this: <select id=\"foo_Bar\" name=\

问题 I\'m trying to retrieve a specific image from a html document, using html agility pack and this xpath: //div[@id=\'topslot\']/a/img/@src As far as I can see, it finds the src-attribute, but it returns the img-tag. Why is that? I would expect the InnerHtml/InnerText or something to be set, but both are empty strings. OuterHtml is set to the complete img-tag. Are there any documentation for Html Agility Pack? 回答1: Html Agility Pack does not support attribute selection. 回答2: You can directly
