我正在尝试从GNUCash XML文件中提取客户数据。最终目标是获取一个逗号分隔值文本文件，显示在XML数据中找到的客户数据。
我使用的命令是
xsltproc transform.xsl data.xml
我的xml输入文件（可以从https://od.lk/d/OV8xMTAwMjI3ODBf/data.xml下载完整文件）：
. . .
<gnc:GncCustomer version="2.0.0">

结果我正在显示我没有下降到所有子元素节点。特别是，我无法显示结算明细。可能是我的XPath表达式错了？
例如，对于Customer2，连续的逗号显示我缺少结算数据：
"000102","a9dbdd1ec6fddad5e068bfa22f5ad93d","Customer2",,,,,,,,,,,,,,,,,"Notes","USEGLOBAL","1","0/1","0/1","ISO4217","USD","1"
我想得到的结果是所有节点的XML数据的逗号分隔值列表，例如：
"000102","a9dbdd1ec6fddad5e068bfa22f5ad93d","Customer2","Billing Name","Billing Address Line 1","Billing Address Line 2","Billing Address Line 3","Billing Address Line 4","Phone","Fax","E-mail","Shipping Name","Shipping Address Line 1","Shipping Address Line 2","Shipping Address Line 3","Shipping Address Line 4","Shipping phone","Shipping fax","Shipping e-mail","Notes","USEGLOBAL","1","0/1","0/1","ISO4217","USD","1"
可能有助于确定XSL适用于 cust：currency 但不适用于 cust：addr 和 cust：shipaddr
答案 0 :(得分：0)
每当输出丢失时，我总是首先查看命名空间。在这种情况下，xsl中addr的命名空间声明为：
的xmlns：ADDR = “http://www.gnucash.org/XML/custaddr”
然而，在xml文件中，它被声明为：
的xmlns：ADDR = “http://www.gnucash.org/XML/addr”
将它们设置为相同的值，我认为一切都应该很好。
顺便说一句，如果您这样编写，那么最终模板会更加整洁：
<xsl:template match="*[ancestor::gnc:GncCustomer]" >
<xsl:value-of select="concat('"', . , '"')"/>
</xsl:template>
