使用 foreach 的 XSLT 映射 [英] XSLT Mapping using foreach

问题描述

这是我正在使用的示例 XML 数据，然后我必须将所有值传递给其他属性标记..

This is the sample XML data that i am using and then i have to pass all the values to an additional properties tag..

<ns1:Quote>
<ns1:QuoteVendor>123</ns1:QuoteVendor>
<ns1:QuoteNumber>sai</ns1:QuoteNumber>
<ns1:QuoteVersion>sri</ns1:QuoteVersion>
<ns1:QuoteValue>sas</ns1:QuoteValue>
<ns1:QuoteProperty>sandy</ns1:QuoteProperty>
</ns1:Quote>

使用 XSLT 转换后，我期望格式为

After transformation using XSLT i am expecting the format as

<AdditionalProperties>
<ns1:Properties>
<ns1:Propertyname>QuoteVendor</ns1:Propertyname>
<ns1:propertyValue>123</ns1:propertyValue>
</ns1:Properties>
<ns1:Properties>
<ns1:Propertyname>QuoteNumber</ns1:Propertyname>
<ns1:propertyValue>sai</ns1:propertyValue>
</ns1:Properties>
<ns1:Properties>
<ns1:Propertyname>QuoteVersion</ns1:Propertyname>
<ns1:propertyValue>sri</ns1:propertyValue>
</ns1:Properties>
<ns1:Properties>
<ns1:Propertyname>QuoteValue</ns1:Propertyname>
<ns1:propertyValue>sas</ns1:propertyValue>
</ns1:Properties>
<ns1:Properties>
<ns1:Propertyname>QuoteProperty</ns1:Propertyname>
<ns1:propertyValue>sandy</ns1:propertyValue>
</ns1:Properties>
</AdditionalProperties>

我目前使用的转换是:

<?xml version="1.0" encoding="UTF-8" ?>
    <?oracle-xsl-mapper
      <!-- SPECIFICATION OF MAP SOURCES AND TARGETS, DO NOT MODIFY. -->
      <mapSources>

          </xsl:for-each>
        </ns1:AdditionalProperties>

    </xsl:stylesheet>

使用后的输出是

<AdditionalProperties>
<ns1:Properties>
<ns1:Propertyname>QuoteVendor</ns1:Propertyname>
<ns1:propertyValue>123</ns1:propertyValue>
</ns1:Properties>
<ns1:Properties>
<ns1:Propertyname>QuoteVersion</ns1:Propertyname>
<ns1:propertyValue>123</ns1:propertyValue>
</ns1:Properties>
</AdditionalProperties>

我没有得到特定标签的文本值.所有值都重复相同的元素.任何人都可以帮助我了解如何做到这一点.

I am not getting the text value for the specific tag.The same element is repeated for all the values. can anyone help me on this on how to do that.

推荐答案

/ns1:Quote/*/text() 总是选择ns1:Quote<的第一个子元素的文本/代码>.

/ns1:Quote/*/text() always select the text of the first child of ns1:Quote.

你可以简单地使用.来获取当前节点的值.

You can simply use . to get the value of the current node.

正如 Dimitre Novatchev 在评论中指出的那样:

As Dimitre Novatchev points out in the comments:

text() ... 选择上下文节点的所有文本节点子节点.然后使用第一个的字符串值(在 XPath 1.0 中，在 XPath 2.0 中，这最常导致类型错误——当期望单个节点时传递的节点序列).如果我们知道有一个文本节点子节点，那么使用点是最短的——.代表上下文节点

text() ... selects all text-node-children of the context node. Then the string-value of the first of these is used (in XPath 1.0, in XPath 2.0 this most often results in type error -- a sequence of nodes passed when a single node expected). If we know that there is a single text-node child, it is the shortest to use a dot -- . which stands for the context node

此外，您可以简单地使用 local-name() 而不是 substring-after(name(),"ns1:").

In addition, instead of substring-after(name(),"ns1:"), you can simply use local-name().
