stax-以字符串形式获取xml节点 [英] stax - get xml node as string

问题描述

xml看起来像这样:

xml looks like so:

<statements>
   <statement account="123">
      ...stuff...
   </statement>
   <statement account="456">
      ...stuff...
   </statement>
</statements>

我正在使用stax一次处理一个"<statement>"，并且可以正常工作.我需要将整个语句节点作为字符串获取，以便可以创建"123.xml"和"456.xml"，甚至可以将其加载到按帐户索引的数据库表中.

I'm using stax to process one "<statement>" at a time and I got that working. I need to get that entire statement node as a string so I can create "123.xml" and "456.xml" or maybe even load it into a database table indexed by account.

使用这种方法: http://www.devx.com/Java/Article/30298/1954

我正在做这样的事情:

String statementXml = staxXmlReader.getNodeByName("statement");

//load statementXml into database

推荐答案

为什么不仅仅为此使用xpath?

Why not just use xpath for this?

您可以使用一个相当简单的xpath来获取所有语句"节点.

You could have a fairly simple xpath to get all 'statement' nodes.

像这样:

//statement

编辑#1:如果可能，请查看 dom4j .您可以读取String并相当简单地获取所有"statement"节点.

EDIT #1: If possible, take a look at dom4j. You could read the String and get all 'statement' nodes fairly simply.

编辑#2:使用dom4j，这是您要执行的操作: (摘自他们的食谱)

EDIT #2: Using dom4j, this is how you would do it: (from their cookbook)

String text = "your xml here";
Document document = DocumentHelper.parseText(text);

public void bar(Document document) {
   List list = document.selectNodes( "//statement" );
   // loop through node data
}
