我正在使用 Mule 3.3.1 CE。
如果 XSL 位于文件外部，我无法让 XSLT 转换器工作。
以下配置有效——它编译并产生预期的单行输出。
<mulexml:xslt-transformer maxIdleTransformers="2" maxActiveTransformers="5" outputEncoding="UTF-8">
<mulexml:xslt-text>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:element name="pocRequest"/>
</xsl:template>
</xsl:stylesheet>
</mulexml:xslt-text>
</mulexml:xslt-transformer>
如果我采用相同的 XSL 并将其移到类路径中的文件 Test.xsl 中，则该文件如下所示：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml"/>
<xsl:template match="/">
<xsl:element name="pocRequest"/>
</xsl:template>
</xsl:stylesheet>
Mule 配置现在如下所示：
<mulexml:xslt-transformer maxIdleTransformers="2" maxActiveTransformers="5" outputEncoding="UTF-8"
xsl-file="Test.xsl"/>
结果是无法编译样式表的异常：
javax.xml.transform.TransformerConfigurationException: Failed to compile stylesheet. 1 error detected.

我不明白我做错了什么。
