使用XQSharp引发的异常使用了使用http://exslt.org/dates-and-times的转换

Question

We have been using MvpXslTransform to perform transforms on using a relatively complex set of XSLT files. In an attempt to improve the performance of the transforms, I am evaluating the XQSharp library.

Unfortunately, when I call ApplyTemplates to perform the transformation, the following exception is raised:

No implementation was found for extension function 'seconds' in namespace 'http://exslt.org/dates-and-times' with arity 1.

Can anyone help me to resolve this issue?

Answer 1

Unfortunately, XQSharp does not natively support the EXSLT functions, which are a set of functions designed to extend XSLT 1.0. These are not included as they are not standard XSLT functions and have mostly been superceded with XSLT 2.0

Have a look at the fn:seconds-from-date , fn:seconds-from-dateTime , fn:seconds-from-time , fn:seconds-from-duration , one of which probably does what you want.

Alternatively, it would be easy to implement this function in XPath 2.0 as an xsl:function in your stylesheet.

Answer 2

或者，您可以从Mvp.Xml修改EXSLT的实现 ，并将其包装为XQSharp本机模块 。
