java - Use XPath to create DOM-Nodes

Question

I'm using javax.xml.xpath to read nodes out of a XML-DOM and to create Java-Objects from the read data. After changing the data of these objects and perhaps creating new objects, I would like to write them back to the XML-DOM. So I was wondering if it is possible to use xpath to also create nodes at specific positions in the XML-DOM. I am not sure if xpath is designed to write to DOM because its a "Query"-Language. But on the other hand SQL is also a query-language and is able to write data to databases.

So my general question is: Is it possible to create DOM-Nodes with XPaths?

Answer 1

不，您将需要使用低级 DOM 方法来创建新节点。

您确定您使用的是正确的方法吗？整个应用程序可以用 XSLT 更容易地编写吗？即使你想使用基于 Java 树的 API，为什么 DOM 与 JDOM 和 XOM 等后续树模型相比如此缓慢和笨拙？

Answer 2

不，据我所知，这是不可能的。但是返回的元素是“活的”，这意味着对它们所做的任何更改都会直接反映在 dom 中。
