我正在尝试遍历XML文档中的一系列节点。当节点不具有LeaveType和jfxpf:等前缀时，我可以找到节点xfa，但是当添加它们时，不会返回任何内容。

这是无效的代码块：
<xsl:for-each select="jfxpf:XPF/jfxpf:Package/jfxpf:Resource/jfxpf:Content/xfa:Data/xfa:DataGroup/Adoption_Leave_PT">
<FormName><xsl:value-of select="LeaveType"/></FormName>
</xsl:for-each>
答案 0 :(得分：1)
这里的问题是您正在重新定义xfa:前缀。选择另一个前缀来寻址源XML中的元素，例如：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:jfxpf="http://www.xfa.com/schema/xml-package"
xmlns:ns0="http://www.xfa.com/schema/xfa-data">
然后：
<xsl:for-each select="jfxpf:XPF/jfxpf:Package/jfxpf:Resource/jfxpf:Content/ns0:Data/ns0:DataGroup/Adoption_Leave_PT">
<FormName><xsl:value-of select="LeaveType"/></FormName>
</xsl:for-each>
