解析不工作在android
我解析从一个URL的XML。该网址有移动IMEI号和基于我的应用程序的搜索字符串。我把我的XML解析代码在Android项目中不起作用。但如果我作为单独的Java程序运行它正在工作。请帮帮我。解析不工作在android
Log.e("rsport-", "function1");
try{
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setIgnoringComments(true);
factory.setCoalescing(true); // Convert CDATA to Text nodes
factory.setNamespaceAware(false); // No namespaces: this is default
factory.setValidating(false); // Don't validate DTD: also default
DocumentBuilder parser = factory.newDocumentBuilder();
Log.e("rsport-", "function2");
Document document = parser.parse("http://demo.greatinnovus.com/restingspot/search?userid=xxxxxxxxxxxxxxxx&firstname=a&lastname=a");
Log.e("rsport-","function3");
NodeList sections = document.getElementsByTagName("Searchdata");
int numSections = sections.getLength();
for (int i = 0; i < numSections; i++)
{
Element section = (Element) sections.item(i);
if(section.hasChildNodes()==true){
NodeList section1=section.getChildNodes();
for(int j=0;j<section1.getLength();j++){
if(section1.item(j).hasChildNodes()==true) {
for(int k=0;k<section1.item(j).getChildNodes().getLength();k++)
xmlvalue=String.valueOf(section1.item(j).getChildNodes().item(k).getNodeValue()).trim();
arl.add(xmlvalue);
}
}
}
}
}
}
catch(Exception e){}
System.out.println("id"+id+" searchdatacount"+searchdatacount);
System.out.println("---------");
ListIterator<String> litr = arl.listIterator();
while (litr.hasNext()) {
String element = litr.next();
Log.e("rsport-", "elememt");
}
之后的Log.e("rsport-", "function2")
;不起作用。
请参阅我的博客,我已经给出了详细解释,http://sankarganesh-info-exchange.blogspot.com/2011/04/parsing-data-from-internet-and-creating.html,并确保您已在您的Manifest文件中添加Internet权限。
如果您已通过Myblog走了,那么你就能够发现你做下面一行是错误
Document document = parser.parse("http://demo.greatinnovus.com/restingspot/search?userid=xxxxxxxxxxxxxxxx&firstname=a&lastname=a");
使用这样
URL url =new URL("http://demo.greatinnovus.com/restingspot/search?userid=xxxxxxxxxxxxxxxx&firstname=a&lastname=a");
Document document= parser.parse(new InputSource(url.openStream()));
hi sangar ganesh i在Logcat中获得以下内容: 它显示异常是InputSource需要流或读取器logcat 04-25 19:01:22.443:ERROR/rsport(2177):{chap = hjdasgdas } 04-25 19:01:22.453:ERROR/listview(2177):[email protected] 04-25 19:01:22.563:ERROR/rsport-(2177):function1 04-25 19:01:22.563 :错误/ rsport-(2177):function2 04-25 19:01:22.583:错误/ rsport ---(2177):InputSource需要流或读取器 – 2011-04-25 13:35:43
感谢shangar它工作 – 2011-04-25 13:51:41
是否抛出异常?什么是logcat输出? – 2011-04-25 13:23:35
告诉我你在Logcat中发生了什么错误以及你想解析的xml中的哪个标记 – 2011-04-25 13:24:38
