一般来说处理xml,采用jdom和dom4j这两种方式解析,这两种方式几乎是一样的,我曾经试了一次,把jdom的jar包移除,在导入dom4j的jar包,使用Eclipse自动修复功能导入,程序完全是可以运行的,可能是我接触到的解析方式都很基础的原因。
1.将输入流转换为String字符串
// 把流转换为字符串
private String convertStreamToString(InputStream is) throws IOException {
BufferedReader reader = null;
StringBuilder builder = new StringBuilder();
if(is == null){
return "";
}
String line = null;
try {
reader = new BufferedReader(new InputStreamReader(is,"UTF-8"));
while ((line = reader.readLine()) != null) {
builder.append(line + "\n");
}
} catch (IOException e) {
throw e;
} finally {
try {
if(is != null){
is.close();
}
} catch (IOException e) {
throw e;
}
}
return builder.toString();
}
2.把String类型转换为Doucument类型
//把字符串转化为xml document
private Document convertStringToDocument(String xmlString) throws DocumentException {
Document doc = null;
if(!xmlString.equals("")){
try {
doc = DocumentHelper.parseText(xmlString);
} catch (DocumentException e) {
throw e;
}
}
return doc;
}
