- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
也许我的问题与这些问题类似
How do I parse this XML in Java with JAXB?
我想生成一些 XML 文件来显示一些数据但我在 JAXB 中正确使用一些 @XmlAttribute 和 @XmlValue 时遇到不同的问题
这是 XML 输出应该是:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<AnlKerja>
<Analisa no="1">
<Kode>B.1</Kode>
<Uraian>some description</Uraian>
<Material>
<item type="value">ID|ID|ID</item>
</Material>
<Jumlah>some value</Jumlah>
</Analisa>
<Analisa no="2">
<Kode>B.3</Kode>
<Uraian>some description</Uraian>
<Material>
<item type="value">ID|ID|ID</item>
<item type="value">ID|ID|ID</item>
</Material>
<Jumlah>some value</Jumlah>
</Analisa>
</AnlKerja>
自从我 2 天前开始使用 JAXB我不知道如何正确使用它,对我来说阅读 JAXB 文档指南有点困难因为我的母语不是英语。这是我的 JAXB
的 java 代码@XmlRootElement(name = "AnlKerja")
public class AnlKerja {
