嵌套样式表的SaxonJS转换导致XError: URI解析失败

Question

我试图使用引用其他xsl样式表的样式表来转换XML。我使用命令行上的xslt3将主样式表编译成一个.sef.json文件，但是当我将.sef.json与.transform()一起使用时，我会得到一个失败的URI解析错误。

我把变换称为：

SaxonJS.transform({
            stylesheetInternal: splXslJS,
            sourceText: input,
            destination: 'serialized'
        }, "async")

fhirXslJS是从这个XSL编译的：

导致错误的行是引用的SPL-Common.xsl中的<xsl:param name="indexingDocumentTypes" select="document('indexing-doc-types.xml')/*"/>：

(这个文件中有更多的内容，但不要认为这是必要的)

这就是我遇到的错误：XError:Failed URI resolution: href=./indexing-doc-types.xml base=file:///C:/Users/7J2197897/Desktop/FDA/SPL-FHIR-Demo/spl-fhir-demo/src/assets/HTML-View-Xform-SPL/spl-common.xsl -- TypeError: r is not a constructor; code:FODC0005

其他可能相关的情况：

这是一个运行在火狐xslt3 -xsl:spl.xsl -export:spl.sef.json --t --nogo --ns:##html5

• sourceText

• Node模块“saxon”上的React应用程序："^2.4.0"，

• 编译的spl.xsl是一个XML字符串，用户输入

• ，我也尝试过用relocate:on和also编译，但是这不能工作H 218f 219

感谢你的帮助！

Answer 1

这很有趣。当然，URI解析不应该失败。(您收到了关于r is not a constructor的奇怪消息，这无疑是一个SaxonJS错误:谢谢！)

当你尝试重新定位时，你说它“不起作用”，它是否以同样的方式失败了？

我个人不太熟悉如何将模块的Node.JS版本打包到浏览器中(这就是它要做的！？)如果您可以尝试加载浏览器版本的SaxonJS而不是Node.js包，这可能会说明情况。

我理解这将是一个很大的要求，但如果你能把它缩小到一个小的测试用例，我可以重现，这将使它更容易确定下来。
