使用Saxon 6.5.5。在使用此命令的Windows命令行中：

java -jar C:\Saxon\Saxon6.5.5\saxon.jar -t -o calimero.xml 0.xml ets4_calimero_gui.xsl

这两个文件位于正确的目录中，输出如下：

'SAXON 6.5.5 from Michael Kay
 Java version 1.6.0_31
 Loading com.icl.saxon.sort.Compare_d
 Preparation time: 225 milliseconds
 Processing file:/C:/Saxon/Saxon6.5.5
 Building tree for file:/C:/Saxon/Sax

 Execution time: 100 milliseconds'

但是创建的calimero.xml只包含以下行：

<?xml version="1.0" encoding="iso-8859-1"?>

有人知道这个问题吗？

谢谢，麦克

Answer 1

您的XML输入位于xmlns：

xmlns="http://knx.org/xml/project/11"

而你的xslt正在寻找

xmlns:b="http://knx.org/xml/project/10"

看起来架构版本已经被提升了：）

Answer 2

这与你的问题没有关系，虽然这与你在XSLT中似乎缺乏经验这一事实有关...

首先，如果您使用Saxon，那么使用XSLT 1.0确实没有任何合理的理由。（甚至更少，“XSLT 1.1”这是一个废弃的工作草案，从未完成）。您应该转到Saxon最新版本（当前版本为9.4）并充分利用使用XSLT 2.0的所有好处。

其次，即使考虑到XSLT 1.0的限制，这也是非常糟糕的代码：

（a）它完全是单一的 - 只有一个模板规则

（b）它使用前一轴，这是非常低效的

（c）它不必要地使用xsl：attribute，这是非常详细的

等

为了让您了解差异，可以像这样创建datapoint元素及其属性（一些改进，但不是全部，取决于XSLT 2.0）：

<datapoint 
    stateBased="true" 
    name="{$verz/@Name}"
    mainNumber="{if (../@DatapointType != '')
                 then if(string-length(../@DatapointType) gt 5)
                      then $master2/../../@Number
                      else $master3/@Number
                 else $master/@Number}"
    dptId="{if (../@DatapointType != '')
            then if (string-length(../@DatapointType) gt 5)
                 then concat($master2/../../@Number, '.',format-number($master2/@Number, '000')
                 else concat($master3/@Number, '.001')
            else concat($master/@Number,'.',format-number($master/b:DatapointSubtypes/b:DatapointSubtype/@Number, '000'))}"
    priority="{(../@Priority, $verz/@Priority)[1]}"

这是51行代码，直到14行，并且可以通过将公共代码片段移动到函数中来进一步降低。

使用Saxon 6.5.5和XLST进行转换无法正常工作
