阅读更多关于 Jsoup POST: Defining a selected option to return HTML?

问题 I'm trying to generate a HTML post to a page which has a list of options. There is a drop down list where the user selects an item and then clicks a generate button.

Bonus question: Is there any reason why

How do I load a local html file into Jsoup?

阅读更多关于 How do I load a local html file into Jsoup?

问题 I can't seem to load in a local html file, using the Jsoup library. Or at the very least it doesn't seem to be recognising it. I hardcoded the exact html in the local file (as the var 'html') and when I switch to that instead of a file input the code works perfectly. But the file is read on both occasions. import java.io.File; import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.nodes.Element; import org.jsoup.select.Elements; public class FileHtmlParser{ public String

问题 I'm having an issue getting JSOUP going on my computer. I've downloaded JSOUP1.8.3 from the web and have tried many things to get it going. I'm running JRE7 on Windows 7.

Here's what I've tried: 1)setting CLASSPATH to point to my JSOUP.jar file. This works with compiling but when I try to run my file I get the error "Could not find or load main Class"
