我对XSLT比较陌生，但我想在元素之间执行我认为相对简单的匹配以获得另一个。
下面是XML的一个片段。版本= 1.0，输出为文本(将xml转换为文本)。

我要做的是匹配节点//Accounts/Account/Id与//InvestmentHoldingBalances/HoldingBalance/AccountId，当有一个匹配得到对应的//Owners/Owner/Id属于该帐户Id。我得到的结果，当我做一个匹配是第一个//所有者/所有者/Id为所有行的不是个人匹配一个。这是我的xslt

输出为每行相同的Owner Id(即'273228M'为最后一列)，而不是根据Account Id匹配的匹配Owner Id;
273228MD399","TEST123","FND","273228M"
273228MD301","0114AU","FND","273228M"

我想要的结果是这样的;
273228MD399","TEST123","FND","2732299"
273228MD301","0114AU","FND","273228M"

谢谢你的建议
基本问题在
<xsl:value-of select="../../Accounts/Account/Owners/Owner/Id"/>
select表达式选择整个文档中的所有所有者id，而不管帐户id是什么，当您请求包含多个节点的value-of a集时，规范将结果定义为文档顺序中集合中第一个节点的值。
您需要以某种方式将集合约束为仅匹配帐户，最简单的方法是
<xsl:value-of select="../../Accounts/Account[Id = current()/AccountId]/Owners/Owner/Id"/>
xsl:output元素之后)定义键可能会更有效
<xsl:key name="accountById" match="Account" use="Id"/>
然后可以使用
在value-of中提取正确的帐户<xsl:value-of select="key('accountById', AccountId)/Owners/Owner/Id"/>
无论哪种方式，您实际上都不需要value-of周围的if，因为在没有帐户与当前AccountId匹配的情况下，您将要求value-of为空节点集，这是根据定义的空字符串。
最后，当你使用<xsl:output method="text"/>时，你不应该需要disable-output-escaping -简单的<xsl:text> </xsl:text>在这里也可以工作。
