尝试做主题。

我正在尝试使用来自文件 (schemasource = 1) 和来自 clob (schemasource = 0) 的 xsd。 我有两个 xsd 模式 common_types.xsd 和 migom.xsd。第二包括第一。 问题是当我使用文件中的 common_types 模式时出现错误

ORA-29532:Java 调用被未捕获的 Java 异常终止:oracle.xml.parser.v2.XMLParseException:发生内部错误情况。

当我仅针对从 clob 读取的第一个模式验证 xml 时，我获得了成功，但是当我添加第二个 xsd 时，我得到了同样的错误，它什么也没说。

我的 oracle 版本是 Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Prod 但我的目标是让它适用于从 9 开始的所有版本

最佳答案

更新:

因此，您将这些文件作为 CLOB 加载到数据库中。将它们插入数据库时​​是否尊重它们的 xml 编码？

关于java - 验证 oracle 的 java 源中的 xml 文档，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/7795866/
