我想将一些内容写入
XML文件.为此我创建了一个
XML文件和带有元素,属性和值的写标签,其中包含以下数据：
XmlSerializer serializer = Xml.newSerializer(); serializer.startTag(null,element); serializer.attribute(null,atbname,value); serializer.text(text); serializer.endTag(null,tag);
如果我想添加一个带有新元素,新属性等的新标签,我会在之前使用标签修改标签的位置输入元素.
如何将新标签附加到先前附加的标签？
解决方法
看一下
this link.它应该让您了解如何向XML添加节点.这是一个片段.
