我需要解析这些信息：标题，艺术家，城市，国家，地理位置，日期和描述
while (parser.next() != XmlPullParser.END_TAG) {
if (parser.getEventType() != XmlPullParser.START_TAG) {
continue;
}
String tag = parser.getName();
MyLog.d(TAG, "tag == " + tag);
if (tag.equals("title")) {
title = readTitle(parser);
MyLog.d(TAG, "tag == " + tag + ": " + title);
} else if (tag.equals("artists")) {
MyLog.d(TAG, "tag == " + tag);
} else if (tag.equals("artist")) {
if (artists == null) {
artists = readArtist(parser);
} else {
artists += ", " + readArtist(parser);
}
MyLog.d(TAG, "tag == " + tag + ": " + artists);
} else if (tag.equals("headliner")) {
artists += ", " + readHeadliner(parser);
MyLog.d(TAG, "tag == " + tag + ": " + artists);
parser.nextTag();
} else if (tag.equals("venue")) {
MyLog.d(TAG, "tag == " + tag);
} else if (tag.equals("location")) {
MyLog.d(TAG, "tag == " + tag);
} else if (tag.equals("city")) {
city = readCity(parser);
MyLog.d(TAG, "tag == " + tag + ": " + city);
} else if (tag.equals("country")) {
country = readCountry(parser);
MyLog.d(TAG, "tag == " + tag + ": " + country);
} else if (tag.equals("geo:point")) {
MyLog.d(TAG, "tag == " + tag);
} else if (tag.equals("geo:lat")) {
geoLat = readGeoLat(parser);
MyLog.d(TAG, "tag == " + tag + ": " + geoLat);
} else if (tag.equals("geo:long")) {
geoLong = readGeoLong(parser);
MyLog.d(TAG, "tag == " + tag + ": " + geoLong);
} else if (tag.equals("startDate")) {
date = readDate(parser);
MyLog.d(TAG, "tag == " + tag + ": " + date);
} else if (tag.equals("description")) {
description = readDescription(parser);
MyLog.d(TAG, "tag == " + tag + ": " + description);
} else {
skip(parser);
}
}
private String readTitle(XmlPullParser parser) throws IOException,
XmlPullParserException {
MyLog.d(TAG, "readTitle");
parser.require(XmlPullParser.START_TAG, ns, "title");
String name = readText(parser);
parser.require(XmlPullParser.END_TAG, ns, "title");
return name;
}
private String readText(XmlPullParser parser) throws IOException,
XmlPullParserException {
MyLog.d(TAG, "readText");
String result = "";
if (parser.next() == XmlPullParser.TEXT) {
result = parser.getText();
parser.nextTag();
}
return result;
}
private void skip(XmlPullParser parser) throws XmlPullParserException,
IOException {
MyLog.d(TAG, "skip");
if (parser.getEventType() != XmlPullParser.START_TAG) {
throw new IllegalStateException();
}
int depth = 1;
while (depth != 0) {
switch (parser.next()) {
case XmlPullParser.END_TAG:
depth--;
break;
case XmlPullParser.START_TAG:
depth++;
break;
}
}
}
我解析除日期和描述之外的所有信息。我认为我的错误是解析后的位置找不到下一个标签。你能改变我的代码或者给我教程如何使用XmlPullParser解析复杂的XML吗？
答案 0 :(得分：0)
我使用此代码运行良好..例如使用此代码..
在解析START_TAG时，解析标记时，取一个计数器变量并将其分配1然后每当你得到标记时，在该增量处它为1.现在，在解析标记时，只检查标记是否第一次出现，如果它然后解析所需的值。
<spaces>
<space>
<name></name>
<desc></desc>
<songs>
<song>
<name></name>
<thumb></thumb>
</song>
<song>
<name></name>
<thumb></thumb>
</song>
</songs>
</space>
</spaces>
case XmlPullParser.START_TAG:
name = parser.getName();
if (name.equalsIgnoreCase("space")) {
cnt=1;
currentSpace = new Space();
System.out.println("space");
} else if (currentSpace != null) {
if (name.equalsIgnoreCase("name"))
{
currentSpace.setName(parser.nextText());
if(cnt==1)
{
// you have <name> from <space>
}
System.out.println(":::"+currentSpace.getName());
cnt++;
} else if (name.equalsIgnoreCase("id")) {
if (currentSpace.getId() == null) {
currentSpace.setId(parser.nextText());
}
}
}
break;
