我正在尝试执行验证以验证xbrl文件。但出现以下错误。
*没有系统ID *的模块的第351行出现错误：

引发的异常是：
net.sf.saxon.s9api.SaxonApiException：找不到名为{http://www.xbrl.org/2010/function/formula}的匹配1参数函数has-fallback-value（）
编辑：
Saxon版本是9.3
XbrlExpressionProcessor类：
构造函数具有以下代码：
net.sf.saxon.s9api.Processor saxonProcessor = new Processor(false);
net.sf.saxon.s9api.XQueryCompiler xqueryCompiler = saxonProcessor.newXQueryCompiler();
registerNamespaces(xqueryCompiler);
在registerNamespaces()方法中，xqueryCompiler.declareNamespace()用于声明名称空间。这里我提到了URL为 http://www.xbrl.org/2010/function/formula 的名称空间xff。 br />
在evaluateExpression()方法中
XQueryExecutable queryExecutable = xqueryCompiler.compile(toCompile.toString()); //This is the line which throws the error mentioned in the problem
XQueryEvaluator xqueryEvaluator = queryExecutable.load();
/*All the variable values are set in the xQueryEvaluator using
xqueryEvaluator.setExternalVariable(new QName(memberName), value)*/
XdmValue xqueryResult = xqueryEvaluator.evaluate();
StringBuilder对象toCompile提供了Saxon处理器的所有功能定义。

我无法告诉您出了什么问题（因为这不是您向我们展示的XML文档...），但是我可以建议一些诊断措施。
您说您正在执行“验证”，但不清楚您的意思。这是XSLT，XPath，XSD吗？我们需要知道您正在执行什么。
此代码过去曾经有用吗？如果是这样，则有确凿的证据表明问题与您的运行方式有关：最可能的罪魁祸首是错误的类路径。
函数{http://www.xbrl.org/2010/function/formula}has-fallback-value()的名称使用的是“抽象” URI，而不是直接标识Java类的URI（类似于{java:net.sf.xbrl.Formula}has-fallback-value()）。这意味着撒克逊人只有在被告知要看的地方时才能找到它。您正在运行的程序必须以某种方式向Saxon注册此扩展。找到此代码（或其文档），看看它可能如何失败。
有一个Saxon配置选项，可获取有关扩展功能加载的诊断信息。在XSLT命令行上，它是-TJ，如果您使用的是Java API，则它是配置属性FeatureKeys.TRACE_EXTERNAL_FUNCTIONS。这向您显示了Saxon为查找匹配的外部函数而采取的步骤，该步骤又向您显示了搜索在失败之前走了多远：例如，搜索是否找到了匹配的类但找不到匹配的方法。鉴于这不是直接标识Java类的URI，因此我对此并不乐观，但值得一试。
检查您正在使用的saxon版本，并查看其是否与您正在运行的应用程序的文档一致。

我知道我参加晚会很晚，但是我会尽力让自己的回答有价值：
您正在显示的是欧洲银行管理局分类法中的一个XML文档。
您要处理的验证不是XML，而是XBRL。因此，为了处理这些验证，您需要了解XBRL规范并加以实施。 （提示：Saxon处理器未实现XBRL规范。）
XBRL定义了所谓的“自定义功能”。这些不是标准XPath的一部分，因此Saxon不知道。 （或其他任何现成的标准XPath处理器。）
您需要实现自定义功能，并向Saxon注册它们，以便处理器知道在哪里可以找到1-argument function named
{http://www.xbrl.org/2010/function/formula}has-fallback-value()。
除非您实际上正在尝试编写自己的XBRL处理器，否则我建议您下载/购买现有的XBRL处理器。
