XML 文档中的节点选择
Node Selection in XML Document
我正在处理一份非结构化 XML 文档，以便将其转换为结构化文档。非结构化文档如下所示
<?xml version="1.0" encoding="UTF-8"?>
<CustomerInformation>

我能够通过创建结构化格式并通过简单地使用节点值和下面的 XSLT 提取相关字段来生成 XML：
<xsl:value-of select=.../>
不过我觉得可能有更好的方法。我希望能够在浏览非结构化或平面文档时控制结构的生成方式。例如，有没有办法对所有 MemberAddress 字段的元素进行分组？如果我能够做到这一点，我就可以创建输出的成员部分。我也可以对其他元素做同样的事情。我担心对结构化文档进行硬编码是因为它将来可能会发生变化。如果可能的话，我希望能够控制输出。源文档中的所有成员信息都应映射到目标文档中的成员元素。源文档中以 OrderedFrom 开头的元素应映射到目标文档中的 Company 字段。 ShipTo 元素又应该映射到目标文档的订单部分中的运输信息，等等。请帮忙！！
My concern with hardcoding the structured document is that it may
change in the future.
XSLT 样式表将数据从一种 XML 模式转换为另一种模式。期望任一架构的更改都不需要重写样式表是不现实的。
Is there a way to group the elements for all MemberAddress fields for
example?
是的，如果你有办法识别它们的话。例如，您可以这样做：
<Member>
<xsl:for-each select="*[starts-with(name(), 'Member')]">
<xsl:element name="{substring-after(name(), 'Member')}">
<xsl:value-of select="." />
</xsl:element>
</xsl:for-each>
</Member>
得到：
<Member>
<Address>String</Address>
<ID>String</ID>
<City>String</City>
<Name>String</Name>
<Type>String</Type>
<State>String</State>
<Since>String</Since>
</Member>
但这不符合您的预期输出。顺便说一句，您的输出显示了很多输入中没有的数据，例如成员的 e-mail.
