Question

java利用xmlparser解析字符串，哪位大侠有示例的？ 网上找不到相关文档...

解析xml字符串 ， 像 <req><command>login</command><version>1.0</version></req>

Answer 1

例：
XML文档：
<?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="伏谨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"烂让 y="60"饥厅局 />
</holes>
</level>

解析：
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();

嗯~ 谢谢 ... 可以问下 相关jar哪里有下 ？ 如果不是文档 是字符串 怎么初始化？

Answer 2

org.dom4j.Document document;
try {
document = org.dom4j.DocumentHelper.parseText(strValue);
List projects = document.selectNodes("/datasource/configclob/锋判querycondition/condition"山简);
Iterator it = projects.iterator();
while (it.hasNext()) {
Element elm = (Element) it.next();
if(((Element) elm.selectObject("银唯改columncode")).getText().equalsIgnoreCase(code)){
defaultValue=((Element) elm.selectObject("value")).getText();
break;
}
}
} catch (Exception ee) {
ee.printStackTrace();
}

.....dom4j 不要这个
