有两件事并不顺利。首先是我如何使用.xsl表中定义的“tabs”格式化输出。第二个是某些结果不太好，例如：

中的值

1） http://vivo.iu.edu/individual/n5798必须为http://vivo.iu.edu/individual/grant42915，这是第二个“描述”集中的值

2） 2001-01-01T00：00：00的两个值都应该是2002-02-02T00：00：00，这是第5组描述中的值

非常感谢

Answer 1

尽管Ian Roberts和Joshua Taylor对使用RDF库处理rdf文件有一点意见，但如果你确定RDF永远不会改变那么使用XSLT就不那么重要了。但是，如果你不是，最好编写自己的方法来编写语句（从RDF库）到XML。

回答你的问题。

格式取决于您的XSLTransformer，我使用Java（javax.xml.transform.Transformer），然后我需要设置这样的标识大小（对于您的变换器可能有所不同）：

TransformerFactory factory = TransformerFactory.newInstance();
Source xslt = new StreamSource(new File("test.xslt"));
Transformer transformer = factory.newTransformer(xslt);
transformer.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "4");

检索错误的结果。你现在这样做的方式并不是做XSLT的正确方法。您的select语句可以定位任何rdf：Description标记并选择相关属性。如果要处理项目，则应编写与此属性匹配的模板，然后处理这些属性。这样的事情（我不完全确定你的数据，所以这可能是错的）：
```
<xsl:template match="rdf:Description">
    <xsl:if test="rdf:type/@rdf:resource='http://vivoweb.org/ontology/core#Project'">
        <cfProj>
            <cfProjId><xsl:value-of select="@rdf:about"/></cfProjId>
```

这将选择每个rdf的rdf：about值：具有Project类型的描述。

XSLT，RDF和XML之间的转换
