加载XML和XSLT从撒克逊9.4he嵌入资源 [英] Load xml and xslt from embedded resource in Saxon 9.4he
问题描述
我使用撒克逊9.4家庭版（撒克逊-HE 9.4 .NET ）来获得对于XSLT 2.0和XPath 2.0和XQuery 1.0 .NET的支持。我的代码崩溃时我加载文件，而一个URI。
- 是否有可能加载XML / XSL文档，而不涉及到加载的文档的URI ？
- 如果没有，有没有办法来定义的URI嵌入的dll文件的元素？
任何其它解决方案也将被理解的是，我的唯一的术语是该文件必须从DLL文件内被加载
只要我的代码工作完全如我加载XML / XSL文件来自：
常量字符串SOURCEPATH = @C：\test\TestInvoiceWithError.xml
常量字符串xsltpath = @C：\test\UBL-T10-BiiRules.xsl
当我尝试从嵌入的资源加载代码抛出一个异常，说明的没有基本URI提供的的：
流的SourceStream = GetEmbeddedResource（TestProject1.testfiles.TestInvoice.xml）;
流xsltStream = GetEmbeddedResource（TestProject1.testfiles.UBL-T10-BiiRules.xsl）;
我也创建乌里对与抛出异常的相对路径资源的'这个操作不支持相对URI的：
乌里sourceUri =新的URI（/ TestProject1;组件/ testfiles /TestInvoice.xml，UriKind.Relative）;
乌里xsltUri =新的URI（/ TestProject1;组件/ testfiles / UBL-T10-BiiRules.xsl.xml，UriKind.Relative）;

我认为你可以从撒克逊流负载，但你需要设置基本URI第一，允许加载任何引用的资源（如DTD XML文档或类似包含或导入的样式表模块）。如果你确信你没有那个那么简单地尝试例如
的DocumentBuilder DB = processor.NewDocumentBuilder（）;
db.BaseUri =新的URI（文件：/// C：/）;
XdmNode输入= db.Build（xsltStream）;
显然，如果你需要，同时也是对XSLT来解析相对URI被加载嵌入的资源更多工作是需要：需要建立的XmlResolver 来，在XSLT与URI的方案支持从嵌入的资源加载资源，一起一类以指示解析器，你需要从资源加载。我不认为.NET框架提供了这样一种的XmlResolver和Uri类不支持的自定义架构无论是。
I am using Saxon 9.4 home edition (Saxon-HE 9.4 .NET) to get support for XSLT 2.0 and XPath 2.0, and XQuery 1.0 in .NET. My code crashes when I load files without an URI.
- Is it possible to load xml/xsl documents without an URI related to the document loaded?
- If not, is there any way to define URI for elements embedded in dll-files?
Any other solutions will also be appreciated, my only term is that the files must be loaded from within the dll-file.
My code works perfectly as long as i load xml/xsl from file:
const string sourcePath = @"C:\test\TestInvoiceWithError.xml";
const string xsltpath = @"C:\test\UBL-T10-BiiRules.xsl";
When i try to load from embedded resource the code throws an exception stating 'No base URI supplied':
Stream sourceStream = GetEmbeddedResource("TestProject1.testfiles.TestInvoice.xml");
Stream xsltStream = GetEmbeddedResource("TestProject1.testfiles.UBL-T10-BiiRules.xsl");
I have also created Uri's for resources with relative path which throws the exception '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);

I think you can load from a stream with Saxon but you need to set a base URI first that would allow to load any references resources (like a DTD in an XML document or like included or imported stylesheet modules). If you are sure you don't have that then simply try e.g.
DocumentBuilder db = processor.NewDocumentBuilder();
db.BaseUri = new Uri("file:///C:/");
XdmNode input = db.Build(xsltStream);
Obviously if you need to resolve relative URIs in the XSLT that are also to be loaded as embedded resource more work is needed: you need to set up the XmlResolver to a class that supports loading the resource from an embedded resource, together with a scheme of URIs in the XSLT to indicate to the resolver that you need to load from a resource. I don't think the .NET framework provides such a kind of XmlResolver and the Uri class does not support a custom schema for that either.
