問題描述

我正在嘗試編寫一個代碼來幫助我創建一個 XML 對象.例如，我將一個字符串作為函數的輸入，它會返回一個 XMLObject.

I am trying to write a code that helps me to create a XML object. For example, I will give a string as input to a function and it will return me a XMLObject.

XMLObject convertToXML(String s) {}

當我在網上搜索時，我通常會看到有關創建 XML 文檔的示例.所以我看到的所有關于創建 XML 并寫入文件并創建文件的事情.但我做過類似的事情:

When I was searching on the net, generally I saw examples about creating XML documents. So all the things I saw about creating an XML and write on to a file and create the file. But I have done something like that:

Document document = new Document();
Element child = new Element("snmp");
child.addContent(new Element("snmpType").setText("snmpget"));
child.addContent(new Element("IpAdress").setText("127.0.0.1"));
child.addContent(new Element("OID").setText("1.3.6.1.2.1.1.3.0"));
document.setContent(child);

您認為創建一個 XML 對象就足夠了嗎?你能幫我如何從 XML 中獲取數據嗎?例如，如何從該 XML 中獲取 IpAdress?

Do you think it is enough to create an XML object? and also can you please help me how to get data from XML? For example, how can I get the IpAdressfrom that XML?

非常感謝大家

編輯 1: 實際上，現在我認為擁有一個像 base.xml 這樣的文件對我來說可能會容易得多，我會將所有基本內容寫入其中例如:

EDIT 1: Actually now I thought that maybe it would be much easier for me to have a file like base.xml, I will write all basic things into that for example:

<snmp>
<snmpType><snmpType>
<OID></OID>
</snmp>

然后使用這個文件創建一個 XML 對象.你怎么看?

and then use this file to create a XML object. What do you think about that?

推薦答案

如果您可以創建字符串 xml，您可以輕松地將其轉換為 xml 文檔對象，例如-

If you can create a string xml you can easily transform it to the xml document object e.g. -

String xmlString = "<?xml version="1.0" encoding="utf-8"?><a><b></b><c></c></a>";  

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();  
DocumentBuilder builder;  
try {  
    builder = factory.newDocumentBuilder();  
    Document document = builder.parse(new InputSource(new StringReader(xmlString)));  
} catch (Exception e) {  
    e.printStackTrace();  
} 

您可以使用文檔對象和xml解析庫或xpath來取回ip地址.

You can use the document object and xml parsing libraries or xpath to get back the ip address.
