使用XSLT在XML中追加重复的元素名？

如果我有一个如下所示的XML文件：

<properties>
    <property>
        <picture>http://example.com/image1.jpg</picture>
        <picture>http://example.com/image2.jpg</picture>
        <picture>http://example.com/image3.jpg</picture>
        <picture>http://example.com/image4.jpg</picture>
        <picture>http://example.com/image5.jpg</picture>
    </property>
</properties>

<properties>
    <property>
        <picture1>http://example.com/image1.jpg</picture1>
        <picture2>http://example.com/image2.jpg</picture2>
        <picture3>http://example.com/image3.jpg</picture3>
        <picture4>http://example.com/image4.jpg</picture4>
        <picture5>http://example.com/image5.jpg</picture5>
    </property>
</properties>

http://example.com/image1.jpg
http://example.com/image2.jpg
http://example.com/image3.jpg
http://example.com/image4.jpg
http://example.com/image5.jpg

如何将其转换为每个图片URL元素都是唯一的，如下所示：

<properties>
    <property>
        <picture>http://example.com/image1.jpg</picture>
        <picture>http://example.com/image2.jpg</picture>
        <picture>http://example.com/image3.jpg</picture>
        <picture>http://example.com/image4.jpg</picture>
        <picture>http://example.com/image5.jpg</picture>
    </property>
</properties>

<properties>
    <property>
        <picture1>http://example.com/image1.jpg</picture1>
        <picture2>http://example.com/image2.jpg</picture2>
        <picture3>http://example.com/image3.jpg</picture3>
        <picture4>http://example.com/image4.jpg</picture4>
        <picture5>http://example.com/image5.jpg</picture5>
    </property>
</properties>

http://example.com/image1.jpg
http://example.com/image2.jpg
http://example.com/image3.jpg
http://example.com/image4.jpg
http://example.com/image5.jpg

假设每个元素必须有相同数量的元素，即使某些元素包含空值（图片URL的数量因属性而异），是否正确？

使用

count（前面的同级：：*）+1

获取当前元素的索引

完整示例：

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<!-- identity transform -->
<xsl:template match="node()|@*">
<xsl:copy><xsl:apply-templates select="node()|@*"/></xsl:copy>
</xsl:template>

<!-- override for picture elements to rename element -->
<xsl:template match="picture">
    <xsl:element name="{name()}{count(preceding-sibling::*)+1}">
        <xsl:apply-templates select="node()|@*"/>
    </xsl:element>
</xsl:template>

</xsl:stylesheet>

使用

计数（前面的同级：：*）+1

</xsl:template>

<xsl:template match="picture">
    <xsl:element name="{name()}{count(preceding-sibling::*)+1}">
        <xsl:apply-templates select="node()|@*"/>
    </xsl:element>
</xsl:template>

</xsl:stylesheet>

</properties>

http://example.com/image1.jpg
http://example.com/image2.jpg
http://example.com/image3.jpg

你似乎遗漏了一个词：“每个uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。对吧，弗朗西斯？不，你不能。它还将计算空白节点，而不仅仅是元素。@FrancisAvila:实际上可以在AVT中使用

position（）

——请参见我的答案。@Kurt，您也可以使用

position（）

而不是

count（前面的同级：：*）+1
