基本上,我想要XML的精确副本,除了我想按ID属性对某些节点进行排序。并非所有具有ID属性的元素都应进行排序。
我已经将一个工作样式表拼凑在了一起,但它要求我将所有兄弟节点的< xsl:apply-template>硬编码到我正在排序的节点上。我没有正式的架构,我不能确定它不会改变。我希望能够创建一个更通用的样式表,它将在没有这些显式调用的情况下输出未排序的节点。
这可能吗?
我转换XML的Java代码:
String input = "C:\\presort.xml";
String output = "C:\\postsort.xml";
String xsl = "C:\\sort.xsl"
Document dom;
try
{
dom = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(input);
Element e = dom.getDocumentElement();
Transformer transform = TransformerFactory.newInstance().newTransformer(
new StreamSource( new File(xsl) ));
StreamResult result = new StreamResult(new File(output));
transform.transform(new DOMSource(dom), result);
}
catch (Exception e)
{
e.printStackTrace();
}
我的XML:
