Xquery 根据元素类型将文本附加到标记值 [英] Xquery append text to tag values depending of the element type

问题描述

我需要获取一些元素的值，然后需要根据元素添加一些文本，例如:

I need to get the values of some elements and then some text needs to be added depending on the element, for example:

<elementType>a</elementType> 
<otherElementType>b</otherElementType> 
<elementType>c</elementType> 
<elementType>d</elementType>

$doc//*[self::elementType or self::otherElementType]/string()

"a"
"b"
"c"
"d"

这会返回值，但我不知道如何获取这样的值:

this returns the values but I don´t know how to get the values like this:

"a is an elementType"
"b is an otherElementType"
"c is an elementType"
"d is an elementType"

推荐答案

您可能希望查看 XSLT 及其基于规则的处理，这似乎与您考虑需求的方式相匹配:

You might like to look at XSLT with its rule-based processing, which seems to match the way you are thinking about your requirements:

使用

<xsl:apply-templates select="*"/>

处理所有元素，然后分开模板规则来说明每种元素如何处理:

to process all the elements, and then separate template rules to say how each kind of element is to be processed:

<xsl:template match="elementType">
  do one thing
</xsl:template>

<xsl:template match="otherElementType">
  do a different thing
</xsl:template>
