一、举例读取的文件为:test.xml
<?xml version="1.0" encoding="UTF-8"?>
<IMIXML>
<SecDef Desc="国债" CentraQuoteBondIndic="Y">
<Instrmt ID="CFT" Sym="现券买卖"/>
</SecDef>
<SecDef Desc="债券" CentraQuoteBondIndic="X">
<Instrmt ID="CCC" Sym="是否"/>
</SecDef>
</IMIXML>

package parseXml; public class Instrmt { private String id; private String sym; public Instrmt() { } public String getId() { return id; } public void setId(String id) { this.id = id; } public String getSym() { return sym; } public void setSym(String sym) { this.sym = sym; } @Override public String toString() { return "Instrmt{" + "id='" + id + '\'' + ", sym='" + sym + '\'' + '}'; } }
四 结果:
