XSL,获取当前工作目录 [英] XSL, get current working directory
问题描述
我正在寻找将当前工作目录存储到变量中的XSL样式表的具体示例。
I'm looking for a concrete example of an XSL stylesheet storing the current working directory into a variable.
我需要这个,因为在我的情况下,我需要使用相对路径导入某些库样式表。了解我的处理器正在选择当前目录的路径就足够了。
I need this because in my situation, I need to import certain library stylesheets using a relative path. Knowing the path my processor is choosing as the current directory would be sufficient.

推荐答案
在XSLT 2.0中,可以使用标准XPath 2.0函数 resolve-uri()。
In XSLT 2.0 one can use the standard XPath 2.0 function resolve-uri().
请注意,包含/导入的样式表模块相对于包含/导入样式表模块的基本URI ,而不是工作目录!
Do note, that the relative URIs of the included/imported stylesheet modules are relative to the base URI of the including/importing stylesheet module -- not from the "working directory"!
以下是W3 F& O规范对此功能的描述的一部分:
Here is part of the description of this function from the W3 F&O specification:
8.1 fn:resolve-uri
8.1 fn:resolve-uri
fn:resolve-uri($ relative as
xs:string?)as xs:anyURI?
fn:resolve-uri($relative as xs:string?) as xs:anyURI?
fn:resolve-uri($ relative as
xs:string?$ base as xs:string)as
xs:anyURI?
fn:resolve-uri($relative as xs:string?, $base as xs:string) as xs:anyURI?
摘要:此函数
的目的是使相对URI解析为
对于一个绝对的URI。
Summary: The purpose of this function is to enable a relative URI to be resolved against an absolute URI.
此函数
的第一种形式从$ b解析了基础uri属性的
的$ relative $ b静态上下文。如果在
静态上下文中没有初始化base-uri
属性,则会出现错误
[err:FONS0005]。
The first form of this function resolves $relative against the value of the base-uri property from the static context. If the base-uri property is not initialized in the static context an error is raised [err:FONS0005].
这是一个非常简单的例子:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text"/>
<xsl:template match="/">
<xsl:sequence select=
"resolve-uri('resolve-uri-example2.xsl')"/>
</xsl:template>
</xsl:stylesheet>
当对任何xml文档(未使用)应用此转换时,结果为:
file:///c:/tests/resolve-uri-example2.xsl
这是正确的结果,因为我们的主要样式表模块保存为:
This is the correct result, because our main stylesheet module is saved as:
c:/tests/resolve-uri-example2.xsl
