XSLT Mapping using foreach

问题:

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>

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>

The transformation that i am using currently is :

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

    </xsl:stylesheet>

The Output after using this is

<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>

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.

回答1:

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

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

As Dimitre Novatchev points out in the comments:

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

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