从XML标签读取特定的字符串

Question

I am using java, I want to read strings from an XML tag. EX: < blank type="Something"> I need to be able to assign "Something" to a variable. Any ideas?

Answer 1

There are a lot of ways to do this:

• You can use the XML APIs provided with Java (SAX or STAX or DOM).

• There are libraries that build on the XML APIs (JDOM, DOM4J, or XOM) which are easier to use than the raw APIs.

• There's Java-XML databinding, described in Pratik's answer . Java-XML databinding is sometimes overkill, depending on your requirements, and when there are errors they can be hard to figure out. Sometimes it's worthwhile, though. I think JiBX is particularly interesting.

If you don't know where to start, start with XOM . XOM was created by a JDOM contributor, it was designed to be easy to use.

Answer 2

What you want to achieve is referred to as Unmarshalling an XML. Unmarshalling means extracting data from an XML document and using it to construct a Java object or graph of objects. There are various APIs available to do the same. You should have a look at the following links:

• JAXB: http://www.oracle.com/technetwork/articles/javase/index-140168.html
• Castor: http://castor.codehaus.org/
• JiBX: http://jibx.sourceforge.net/
