从Xml.parse退出时发现匹配 [英] Exiting from Xml.parse when match is found
问题描述
我使用了Android SAX解析器在一个相当大的(6MB)XML文件来搜索条目。我基本上使用清单8的此处。我的问题是我怎么停止解析一次,我发现匹配?显示的code继续通过文件的末尾解析,但我想在那之前停下来。这是可能的,或者我需要使用比SAX以外的东西(例如XmlPullParser?)
I'm using the Android SAX parser to search for entries in a rather large (6MB) XML file. I'm basically using a derivative of the code shown in listing 8 here. The question I have is how do I stop parsing once my match has been found? The code shown continues parsing through the end of the file but I want to stop before then. Is this possible or do I need to use something other than SAX (e.g. XmlPullParser?)
推荐答案
生成的ArithmeticException并抓住它!如果(条件){int类型的= 1;一个/ = 0; }
...
Generate an ArithmeticException and catch it !
if (condition) { int a=1; a/=0; }
...
try {
Xml.parse(this.getInputStream(), Xml.Encoding.UTF_8, root.getContentHandler());
}
catch (ArithmeticException e) {
return true;
}
这是可怕的,但它的工作原理...
That's awful but it works...
