此代码用于从其String表示生成XML文档.它在我的小单元测试中工作正常,但在我的实际xml数据中失败了.它触发的行是Document doc = db.parse(is);
有任何想法吗?
public static Document FromString(String xml)
{
// from http://www.rgagnon.com/javadetails/java-0573.html
try
{
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(xml));
Document doc = db.parse(is);
doc.normalize();
return doc;
}
catch (Exception e)
{
Log.WriteError("Failed to parse XML", e, "XML.FromString(String)");
return null;
}
}
