我正在尝试在 Android 上将 XSLT 转换为 HTML，有人推荐 XALAN。我能够得到 xalan jar 和 jarjar（重命名包）它，这成功地转换了 xslt，出现 1 个错误。错误是其中一个 div 未在 html 输出中呈现。

我认为错误的原因是当转换器遇到ms-xsl节点集时，它无法解析它并抛出声明的错误。

片段

<xsl:when test="function-available('msxsl:node-set')">
    <xsl:apply-templates select="msxsl:node-set($mixinRtf)/*"/>
</xsl:when>
<xsl:otherwise>
    <!-- XSLT 2 would be thus: xsl:apply-templates select="$mixinRtf/*"/ -->
    <xsl:message terminate="yes">required function node-set is not available, this XSLT processor cannot handle the transform</xsl:message>
</xsl:otherwise>

进行转换的 Java Snippet

        Source xmlSource = new StreamSource(new BufferedInputStream(getAssets().open("sample1.xml")));
        Source xsltSource = new StreamSource(new BufferedInputStream(getAssets().open("spl.xsl")));

        xmlSource.setSystemId(xmlSource.getSystemId());
        xsltSource.setSystemId(xsltSource.getSystemId());

        TransformerFactoryImpl transFact = new TransformerFactoryImpl();
        transFact.setURIResolver(new URIResolver() {
            @Override
            public Source resolve(String href, String base) throws TransformerException {
                try {
                    return new StreamSource(new BufferedInputStream(getAssets().open(href)));
                } catch (IOException e) {
                    e.printStackTrace();
                    return null;
                }
            }
        });

        TransformerImpl trans = (TransformerImpl) transFact.newTransformer(xsltSource);
        File f = new File(Environment.getExternalStorageDirectory().getAbsolutePath() + "/mydata.html");

        StreamResult result = new StreamResult(f);
        trans.transform(xmlSource, result);

这（还）不是答案，只是验证您的假设的一种方式。

运行以下两个样式表（针对任何有效的 XML 输入）并报告结果：

样式表 #1

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan" 
xmlns:exsl="http://exslt.org/common"
exclude-result-prefixes="xalan exsl">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:template match="/">
    <results>
        <function name="xalan:nodeset">
            <xsl:value-of select="function-available('xalan:nodeset')"/>
        </function>
        <function name="exsl:node-set">
            <xsl:value-of select="function-available('exsl:node-set')"/>
        </function>     
    </results>
</xsl:template>     

</xsl:stylesheet>

样式表 #2

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xalan="http://xml.apache.org/xalan" 
xmlns:exsl="http://exslt.org/common"
exclude-result-prefixes="xalan exsl">
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>

<xsl:variable name="items">
    <item>A</item>
    <item>B</item>
    <item>C</item>
</xsl:variable>

<xsl:template match="/">
    <results>
        <test name="xalan:nodeset">
            <xsl:copy-of select="xalan:nodeset($items)/item[2]"/>   
        </test>
        <test name="exsl:node-set">
            <xsl:copy-of select="exsl:node-set($items)/item[2]"/>   
        </test> 
    </results>
</xsl:template>     

</xsl:stylesheet>
