Parsing a tag with JSOUP force closing for nullPointerException
When trying to parse the link
http://pc.gamespy.com/pc/bastion/
using
Element overview = doc.select("div#object-overview").last();
Element paragraph = overview.select("p").last();
It gives me a nullpointerexception.
And also with t开发者_如何学运维his one
http://wii.gamespy.com/wii/jerry-rice-nitus-dog-football/
it gives null pointer here
Element featureList = doc.select("div.callout-box").last();
featuresText.setText("FEATURE: " + featureList.text());
Why is this? I am trying to retrieve the overview section. it works for all the other items.
On the first one you should be able to simply call
Element overview = doc.select("#object-overview").last();
You shouldn't need the div as part of it since object-overview
is an id
. You were getting the NullPointerException because the expression in your select was incorrect, so select
returned null because it couldn't find anything.
Not sure why the second one wouldn't work for you. I can see there is at least one div with the class callout-box. Unless featuresText
is null?
According to http://jsoup.org/apidocs/, Jsoup throws NullPointerException
if the argument is null. In other words rather .select("div#object-overview")
returns null or .select("p")
. Try to check for null first, then use .last()
method like this
Elements overviews = doc.select("div#object-overview");
if(!overview==null){
Element overview = overviews.last();
}
etc
