Since you are converting your XML to Java objects, I will demonstrate how this could be done using a <a href="http://jcp.org/en/jsr/detail?id=222" rel="nofollow">JAXB (JSR-222)</a> implementation. A JAXB implementation is included in the JDK/JRE starting with Java SE 6.

I would recommend changing the contents of the <code>NEARBOXID</code> element to be space separated.

<pre><code>&lt;NEARBOXID&gt;2 3 4 5&lt;/NEARBOXID&gt;
</code></pre>

The corresponds to the following entry in an XML schema. This means that you could validate that the element contains space separated int values instead of space separated Strings. 

<pre><code> &lt;xs:element name="NEARBOXID" minOccurs="0"&gt;
 &lt;xs:simpleType&gt;
 &lt;xs:list itemType="xs:int"/&gt;
 &lt;/xs:simpleType&gt;
 &lt;/xs:element&gt;
</code></pre>

Config

Then you could map the element using JAXB's <code>@XmlList</code> annotation (see: <a href="http://blog.bdoughan.com/2010/09/jaxb-collection-properties.html" rel="nofollow">http://blog.bdoughan.com/2010/09/jaxb-collection-properties.html</a>).

<pre><code>import javax.xml.bind.annotation.*;

@XmlAccessorType(XmlAccessType.FIELD)
public class Config {

 @XmlElement(name="BOXID")
 private int boxId;

 @XmlElement(name="LENGTH")
 private int length;

 @XmlElement(name="NEARBOXID")
 @XmlList
 private int[] nearBoxIds;

}
</code></pre>

Configuration

The object below would map to the root of your XML document.

<pre><code>import java.util.List;
import javax.xml.bind.annotation.*;

@XmlRootElement(name="CONFIGURATION")
@XmlAccessorType(XmlAccessType.FIELD)
public class Configuration {

 @XmlElement(name="CONFIG")
 private List&lt;Config&gt; configs;

}
</code></pre>

Demo

Below is some demo code to prove that everything works.

<pre><code>import java.io.File;
import javax.xml.bind.*;

public class Demo {

 public static void main(String[] args) throws Exception {
 JAXBContext jc = JAXBContext.newInstance(Configuration.class);

 Unmarshaller unmarshaller = jc.createUnmarshaller();
 File xml = new File("src/forum14305301/input.xml");
 Configuration configuration = (Configuration) unmarshaller.unmarshal(xml);

 Marshaller marshaller = jc.createMarshaller();
 marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
 marshaller.marshal(configuration, System.out);
 }

}
</code></pre>

input.xml/Output

Below is the input to and output from running the demo code.

<pre><code>&lt;?xml version="1.0" encoding="UTF-8" standalone="yes"?&gt;
&lt;CONFIGURATION&gt;
 &lt;CONFIG&gt;
 &lt;BOXID&gt;1&lt;/BOXID&gt;
 &lt;LENGTH&gt;100&lt;/LENGTH&gt;
 &lt;NEARBOXID&gt;2 3 4 5&lt;/NEARBOXID&gt;
 &lt;/CONFIG&gt;
 &lt;CONFIG&gt;
 &lt;BOXID&gt;2&lt;/BOXID&gt;
 &lt;LENGTH&gt;200&lt;/LENGTH&gt;
 &lt;NEARBOXID&gt;1 8&lt;/NEARBOXID&gt;
 &lt;/CONFIG&gt;
&lt;/CONFIGURATION&gt;
</code></pre>

blocks|key|486814|text|我认为这是一个选择的问题。您可以这样使用它：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|486815|<NEARBOXID>2,3,4,5</NEARBOXID>|code-block|syntax|javascript|486816|或者你这样使用它：|486817|<NEARBOXID>2</NEARBOXID>
<NEARBOXID>3</NEARBOXID>
<NEARBOXID>4</NEARBOXID>
<NEARBOXID>5</NEARBOXID>|486818|第二种方法要求您使用与第一种方法不同的解析代码，但您可以节省一些拆分和处理字符串的代码。|486819|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I think it is a matter of choice. You can use it that way as:

<pre><code>&lt;NEARBOXID&gt;2,3,4,5&lt;/NEARBOXID&gt;
</code></pre>

or you use it that way:

<pre><code>&lt;NEARBOXID&gt;2&lt;/NEARBOXID&gt;
&lt;NEARBOXID&gt;3&lt;/NEARBOXID&gt;
&lt;NEARBOXID&gt;4&lt;/NEARBOXID&gt;
&lt;NEARBOXID&gt;5&lt;/NEARBOXID&gt;
</code></pre>

Second way requires you to have different parsing code than the first one, but you can save some code on splitting and dealing with string.

blocks|key|486841|text|将数据提取为字符串并对其执行split()。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|486842|更好的方法是在单个标记中维护，比如|486843|<NEARBOXID>2</NEARBOXID>

Extract the data as a String and perform split() on it.

Better approach for it is to maintain in individual tags like

<pre><code>&lt;NEARBOXID&gt;2&lt;/NEARBOXID&gt;
&lt;NEARBOXID&gt;3&lt;/NEARBOXID&gt;
&lt;NEARBOXID&gt;4&lt;/NEARBOXID&gt;
&lt;NEARBOXID&gt;5&lt;/NEARBOXID&gt;
</code></pre>

For parsing the xml query you can use XPath, XQuery or JAXB depending on your requirement.

i'm reading an xml file which contain the attributes of many objects of a Class; I'm using a DOM xml parser; in this Class there is also an array field (NEARBOXID), so I would know if is a good way to read it from the xml file like a single String and then split its content, or is there any better way to do this?

the file is like this:

<pre><code>&lt;CONFIGURATION&gt;
&lt;CONFIG&gt; 
 &lt;BOXID&gt;1&lt;/BOXID&gt; 
 &lt;LENGTH&gt;100&lt;/LENGTH&gt;
 &lt;NEARBOXID&gt;2,3,4,5&lt;/NEARBOXID&gt;
&lt;/CONFIG&gt;
 &lt;CONFIG&gt; 
 &lt;BOXID&gt;2&lt;/BOXID&gt; 
 &lt;LENGTH&gt;200&lt;/LENGTH&gt;
 &lt;NEARBOXID&gt;1,8&lt;/NEARBOXID&gt;
&lt;/CONFIG&gt;
</code></pre>

我正在读取一个xml文件，它包含一个类的许多对象的属性；我正在使用一个DOM xml解析器；在这个类中还有一个数组字段(NEARBOXID)，所以我想知道从xml文件中像读取单个字符串一样读取它然后拆分其内容是不是一个好方法，或者有没有更好的方法呢？该文件如下所示：<CONFIGURATION><CONFIG> <BOXID>1</BOXID> <LENGTH>100</LENGT
