我的XSLT工作得很好，但我遇到了一些问题。
首先，它不产生ROOT元素。
其次，XML数据有两个元素<ACPGDEGREE1>和<CCD11>。当一个包含数据时，另一个是空的，反之亦然。如果<ACPGDEGREE1>包含数据，我想插入数据并添加文本＆＃34; DEGREE＆＃34;在它之后。如果<CCD11>包含数据，我想忽略数据但插入文本＆＃34;证书＆＃34;。
非常感谢任何帮助。
这是XSLT：

答案 0 :(得分：1)
没有根元素的原因是你没有编写任何会生成它的代码。通常的方法是使模板匹配源文档的根，例如
<xsl:template match="/">
<root>
<xsl:apply-templates/>
</root>
</xsl:template>
此要求声明：
If <ACPGDEGREE1> contains data, I want to insert the data and add the text "DEGREE" after it. If <CCD11> contains data, I want to ignore the data but insert the text "CERTIFICATE".
似乎很容易映射到两个模板规则中：
<xsl:template match="ACPGDEGREE1[child::node()]">
<xsl:value-of select="."/>
<xsl:text> DEGREE</xsl:text>
</xsl:template>
<xsl:template match="CCD11[child::node()]">
<xsl:text> CERTIFICATE</xsl:text>
</xsl:template>
你已经找到了如何用一套规则来表达你的要求（当我看到这个时，我想这样做）但是你似乎没有意识到XSLT编码主要是翻译这些规则直接进入模板规则。
