XmlResourceParser使用例子

对于像这样一个xml文件:

<?xml version="1.0" encoding="UTF-8"?>
<level>
    <begin x="80" y="415" />
    <end x="720" y="415" />
    <walls count="3">
        <wall left="195" top="130" right="201" bottom="477" />
        <wall left="400" top="6" right="406" bottom="352" />
        <wall left="605" top="130" right="611" bottom="477" />
    </walls>
    <holes count="5">
        <hole x="130" y="106" />
        <hole x="270" y="106" />
        <hole x="270" y="424" />
        <hole x="470" y="328" />
        <hole x="730" y="60" />
    </holes>
</level>

可以这样来读取

           XmlResourceParser xmlParser = this.mActivity.getResources().getXml(R.xml.level001 + idxLevelXml);

		int eventType = xmlParser.getEventType();

		while (eventType != XmlResourceParser.END_DOCUMENT)

		{

			if(eventType == XmlResourceParser.START_TAG)

			{

				String strName = xmlParser.getName();

				if (strName.equals("begin"))

				{

					int m = xmlParser.getAttributeIntValue(0, -1);

					int n = xmlParser.getAttributeIntValue(1, -1);

					setBBegin(m, n);

				}

				else if(strName.equals("end"))

				{

					int i2 = xmlParser.getAttributeIntValue(0, -1);

					int i3 = xmlParser.getAttributeIntValue(1, -1);

					setEnd(i2, i3);

				}

				else if(strName.equals("walls"))

				{

					int nWallCnt = xmlParser.getAttributeIntValue(0, 0);

					mwalls = new Rect[nWallCnt];

					int nCount = 0;

					do

					{

						if(XmlResourceParser.START_TAG == xmlParser.getEventType()

							&& xmlParser.getName().equals("wall"))

						{

							int iLeft = xmlParser.getAttributeIntValue(0, -1);

							int iTop = xmlParser.getAttributeIntValue(1, -1);

							int iRight = xmlParser.getAttributeIntValue(2, -1);

							int iBottom = xmlParser.getAttributeIntValue(3, -1);

							mWalls[nCount] =  new Rect(iLeft, iTop, iRight, iBottom);

							nCount ++;

						}	

						xmlParser.next();

					}while(nCount < nWallCnt);



				}

				else if (strName.equals("holes"))

				{

					int nHoleCnt = xmlParser.getAttributeIntValue(0, 0);

					mHoles = new Point[nHoleCnt];

					int nCount = 0;

					do

					{

						if(XmlResourceParser.START_TAG == xmlParser.getEventType()

								&& xmlParser.getName().equals("hole"))

						{

							int iX = xmlParser.getAttributeIntValue(0, -1);

							int iY = xmlParser.getAttributeIntValue(1, -1);

							mHoles[nCount] = new Point(iX, iY);

							nCount++;

						}

						xmlParser.next();

					}while(nCount < nHoleCnt);

				}

			}

			eventType = xmlParser.next();

		}

		xmlParser.close();
