我正在使用 Saxon 9.4 Home Edition (Saxon-HE 9.4 .NET) 来支持在 .NET 中使用 XSLT 2.0,XPath 2.0 和 XQuery 1.0 技术。当我加载没有 URI 的文件时,我的代码会崩溃。
以下是需要翻译的问题:
只要我从文件中加载 xml/xsl,我的代码就能够完美运行。
当我尝试从嵌入的资源加载时,代码会抛出一个异常,指出“未提供基本URI”。
以下是需要翻译的问题:
- 是否可以加载没有与所加载文档相关的 URI 的 xml/xsl 文档?
- 如果不行,是否有任何方法来为嵌入到 dll 文件中的元素定义 URI?
只要我从文件中加载 xml/xsl,我的代码就能够完美运行。
const string sourcePath = @"C:\test\TestInvoiceWithError.xml";
const string xsltpath = @"C:\test\UBL-T10-BiiRules.xsl";
当我尝试从嵌入的资源加载时,代码会抛出一个异常,指出“未提供基本URI”。
Stream sourceStream = GetEmbeddedResource("TestProject1.testfiles.TestInvoice.xml");
Stream xsltStream = GetEmbeddedResource("TestProject1.testfiles.UBL-T10-BiiRules.xsl");
我还为相对路径的资源创建了Uri,但这会抛出异常'This operation is not supported for a relative URI.':
Uri sourceUri = new Uri("/TestProject1;component/testfiles/TestInvoice.xml", UriKind.Relative);
Uri xsltUri = new Uri("/TestProject1;component/testfiles/UBL-T10-BiiRules.xsl.xml", UriKind.Relative);
