EclipseLink MOXy @XmlPath支持axis / parent [英] EclipseLink MOXy @XmlPath support for axes/parent

问题描述

以下任何XPath表达式是否可以接受？使用eclipselink的2.3.1版本

Are any of the following XPath expressions acceptable? Using version 2.3.1 of eclipselink

@XmlPath("../header/@type")
@XmlPath("/root/header/@type")
@XmlPath("parent::*/header/@type")

基本上这是在XML文档中重复的类（ / root / tag ），如果不清楚我会详细说明。

Basically this is in a class which repeats within the XML document (/root/tag), if that isn't clear I'll elaborate.

我正试图遍历树而不是向下。我的其他 @XmlPath 注释工作正常。

I'm trying to traverse up the tree rather than down. My other @XmlPath annotations are working fine.

推荐答案

EclipseLink JAXB（MOXy） 目前不支持axis / parent。如果您对此类支持感兴趣，请输入增强请求：

EclipseLink JAXB (MOXy) does currently not support axes/parent. If you are interested in this kind of support please enter an enhancement request:

• https://bugs.eclipse.org/bugs/enter_bug.cgi?product=EclipseLink

• https://bugs.eclipse.org/bugs/enter_bug.cgi?product=EclipseLink

它确实支持XPath：

It does support XPath like:

• @XmlPath（。）/ /映射到自身节点，在将两个对象映射到同一元素时很有用


• @XmlPath（@ foo）//映射到属性


• @ XmlPath（foo）//映射到元素


• @XmlPath（foo [2]）//映射到第二次出现


• @XmlPath（foo [@ bar ='Hello World']）//使用值为Hello World的bar属性映射到foo元素


• @XmlPath（ns1：foo / ns2：@bar）//映射到命名空间限定节点

• @XmlPath(".") // Map to self node, useful when mapping two objects to same element
• @XmlPath("@foo") // Map to attribute
• @XmlPath("foo") // Map to element
• @XmlPath("foo[2]") // Map to 2nd occurence of
• @XmlPath("foo[@bar='Hello World']") // Map to foo element with bar attribute with value "Hello World"
• @XmlPath("ns1:foo/ns2:@bar") // Map to namespace qualified nodes
