有如下xml文件：
<?xml version="1.0" encoding="GB2312"?>
<usecase>
<usecasename>initialize</usecasename>
<precondition>idle</precondition>
<precondition>managefail</precondition>
<precondition>connectfail</precondition>
<scenario>

当我用ＪＤＯＭ的addContent方法给ｕｓｅｃａｓｅ节点添加一个元素<precondition>newPrecondition</precondition>后，整个文件结构变成下列这种格式(注意黑体部分)：
<?xml version="1.0" encoding="GB2312"?>
<usecase>
<usecasename>initialize</usecasename>
<precondition>idle</precondition>
<precondition>managefail</precondition>
<precondition>connectfail</precondition>
<scenario>
<scenarioname>scn1</scenarioname>
<scenarioprobability>1</scenarioprobability>
<postcondition>initialized</postcondition>
<critical>true</critical>
<message>
<messagename>IN</messagename>
<sender>GCS</sender>
<receiver>SCS</receiver>
<time>t0</time>
<timeconstraint>null</timeconstraint>
</message>
<message>
<messagename>INA</messagename>
<sender>SCS</sender>
<receiver>GCS</receiver>
<time>t1</time>
<timeconstraint>null</timeconstraint>
</message>
</scenario>
<ｐｒｅｃｏｎｄｉｔｉｏｎ>ｎｅｗＰｒｅｃｏｎｄｉｔｉｏｎ</ｐｒｅｃｏｎｄｉｔｉｏｎ>
</usecase>
<p>

而我希望生成这种格式(注意黑体部分)：
<?xml version="1.0" encoding="GB2312"?>
<usecase>
<usecasename>initialize</usecasename>
<precondition>idle</precondition>
<precondition>managefail</precondition>
<precondition>connectfail</precondition>
<ｐｒｅｃｏｎｄｉｔｉｏｎ>ｎｅｗＰｒｅｃｏｎｄｉｔｉｏｎ</ｐｒｅｃｏｎｄｉｔｉｏｎ>
<scenario>
<scenarioname>scn1</scenarioname>
<scenarioprobability>1</scenarioprobability>
<postcondition>initialized</postcondition>
<critical>true</critical>
<message>
<messagename>IN</messagename>
<sender>GCS</sender>
<receiver>SCS</receiver>
<time>t0</time>
<timeconstraint>null</timeconstraint>
</message>
<message>
<messagename>INA</messagename>
<sender>SCS</sender>
<receiver>GCS</receiver>
<time>t1</time>
<timeconstraint>null</timeconstraint>
</message>
</scenario>
</usecase>

怎样才能让一个ｄｏｃｕｍｅｎｔ中或者同一节点下名字相同的子节点连在一起。这样看起来整个文档的结构会更加清晰。
