How to add a node to XML with XMLBeans XmlObject
提问by wsams
My goal is to take an XML string and parse it with XMLBeans XmlObject and add a few child nodes.
我的目标是获取一个 XML 字符串并使用 XMLBeans XmlObject 解析它并添加一些子节点。
Here's an example document (xmlString),
这是一个示例文档（xmlString），
<?xml version="1.0"?>
<rootNode>
<person>
<emailAddress>[email protected]</emailAddress>
</person>
</rootNode>
Here's the way I'd like the XML document to be after adding some nodes,
这是添加一些节点后我希望 XML 文档的方式，
<?xml version="1.0"?>
<rootNode>
<person>
<emailAddress>[email protected]</emailAddress>
<phoneNumbers>
<home>555-555-5555</home>
<work>555-555-5555</work>
<phoneNumbers>
</person>
</rootNode>
Basically, just adding the <phoneNumbers/>node with two child nodes <home/>and <work/>.
基本上，只需添加<phoneNumbers/>具有两个子节点的节点<home/>和<work/>.
This is as far as I've gotten,
这是我得到的，
XmlObject xml = XmlObject.Factory.parse(xmlString);
Thank you
谢谢

XMLBeans seems like a hassle, here's a solution using XOM:
XMLBeans 看起来很麻烦，这里有一个使用XOM的解决方案：
import nu.xom.*;
Builder = new Builder();
Document doc = builder.build(new java.io.StringBufferInputStream(inputXml));
Nodes nodes = doc.query("person");
Element homePhone = new Element("home");
homePhone.addChild(new Text("555-555-5555"));
Element workPhone = new Element("work");
workPhone.addChild(new Text("555-555-5555"));
Element phoneNumbers = new Element("phoneNumbers");
phoneNumbers.addChild(homePhone);
phoneNumbers.addChild(workPhone);
nodes[0].addChild(phoneNumbers);
System.out.println(doc.toXML()); // should print modified xml

Here is an example of using the XmlCursor to insert new elements. You can also get a DOM Node for an XmlObject and using those APIs.
下面是使用 XmlCursor 插入新元素的示例。您还可以获得 XmlObject 的 DOM 节点并使用这些 API。
import org.apache.xmlbeans.*;
/**
* Adding nodes to xml using XmlCursor.
* @see http://xmlbeans.apache.org/docs/2.4.0/guide/conNavigatingXMLwithCursors.html
* @see http://xmlbeans.apache.org/docs/2.4.0/reference/org/apache/xmlbeans/XmlCursor.html
*/
public class AddNodes
{
public static final String xml =
"<rootNode>\n" +
" <person>\n" +
" <emailAddress>[email protected]</emailAddress>\n" +
" </person>\n" +
"</rootNode>\n";
public static XmlOptions saveOptions = new XmlOptions().setSavePrettyPrint().setSavePrettyPrintIndent(2);
public static void main(String[] args) throws XmlException
{
XmlObject xobj = XmlObject.Factory.parse(xml);
XmlCursor cur = null;
try
{
cur = xobj.newCursor();
// We could use the convenient xobj.selectPath() or cur.selectPath()
// to position the cursor on the <person> element, but let's use the
// cursor's toChild() instead.
cur.toChild("rootNode");
cur.toChild("person");
// Move to </person> end element.
cur.toEndToken();
// Start a new <phoneNumbers> element
cur.beginElement("phoneNumbers");
// Start a new <work> element
cur.beginElement("work");
cur.insertChars("555-555-5555");
// Move past the </work> end element
cur.toNextToken();
// Or insert a new element the easy way in one step...
cur.insertElementWithText("home", "555-555-5555");
}
finally
{
if (cur != null) cur.dispose();
}
System.out.println(xobj.xmlText(saveOptions));
}
}

It may be a little difficult to manipulate the objects using just the XmlObject interface. Have you considered generating the XMLBEANS java objects from this xml?
仅使用 XmlObject 接口操作对象可能有点困难。您是否考虑过从此 xml 生成 XMLBEANS java 对象？
If you don't have XSD for this schema you can generate it using XMLSPY or some such tools.
如果您没有此模式的 XSD，您可以使用 XMLSPY 或一些此类工具生成它。
If you just want XML manipulation (i.e, adding nodes) you could try some other APIs like jdom or xstream or some such thing.
如果您只想要 XML 操作（即添加节点），您可以尝试其他一些 API，例如 jdom 或 xstream 或类似的东西。

Method getDomNode()gives you access to the underlying W3C DOM Node. Then you can append childs using W3C Document interface.
方法getDomNode()使您可以访问底层的 W3C DOM 节点。然后您可以使用 W3C Document 接口附加孩子。
