java - 从 xml 文件执行验证时出错

转载作者：行者123 更新时间：2023-12-02 10:58:32

我正在尝试执行验证以验证 xbrl 文件。但出现以下错误。

Error on line 351 of *module with no systemId*:
XPST0017: Cannot find a matching 1-argument function named
{http://www.xbrl.org/2010/function/formula}has-fallback-value()

抛出的异常是:

net.sf.saxon.s9api.SaxonApiException: Cannot find a matching 1-argument function named {http://www.xbrl.org/2010/function/formula}has-fallback-value()

编辑:
撒克逊版本是9.3

XbrlExpressionProcessor 类:构造函数有以下代码:

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()用于声明命名空间。这里我提到了命名空间xff与网址 http://www.xbrl.org/2010/function/formula 。
在 evaluateExpression() 方法

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Saxon处理器的所有函数定义。
它包含以下数据:

最佳答案

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...)，但我可以建议一些诊断操作。

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。
这段代码过去有用过吗？如果是这样，那就有明确的证据表明问题与您运行它的方式有关:最有可能的罪魁祸首是不正确的类路径。
函数的名称{http://www.xbrl.org/2010/function/formula}has-fallback-value()使用的是“抽象”URI，而不是而不是直接标识 Java 类(类似于 {java:net.sf.xbrl.Formula}has-fallback-value())。这意味着撒克逊人只有被告知去哪里寻找才能找到它。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)并查看它可能会失败的原因。
有一个 Saxon 配置选项，用于获取有关扩展函数加载的诊断信息。在 XSLT 命令行上，它是 -TJ，如果您使用 Java API，那么它是配置属性 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，这反过来又向您显示了搜索失败之前的情况:例如，它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，我并不乐观这会透露太多信息，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。
