Question

我尝试添加类似于以下saml的XML元素：AttributeValue，

<ABC>cde</ABC>

使用DocumentBuilderFactory获取XML元素，并使用以下代码获取XSAny类型对象。

XSAnyBuilder anyBuilder = (XSAnyBuilder)Configuration.getBuilderFactory().getBuilder(XSAny.TYPE_NAME);
XSAny any = anyBuilder.buildObject(AttributeValue.DEFAULT_ELEMENT_NAME, XSAny.TYPE_NAME);
XSAny xo = anyBuilder.buildObject(xmlElement);

但是我从第3行得到了错误，

Caused by: java.lang.IllegalArgumentException: local part cannot be "null" when creating a QName

有关于此的任何想法吗？

您无法直接将XML添加为AttributeValue，因为它会破坏Assertion XML架构。

最好的解决方案是在插入XML之前转义XML：

&lt;ABC&gt;cde&lt;/ABC&gt;

如何在OpenSAML中添加简单的XML元素作为AttributeValue？
