如何使用xslt转换为XML元素添加ID属性

Question

I am very new to xml and xslt transformation. I need some advice.

Basically I have managed to display a range of images from my XML page using XLTR Transformation.

The original xml has no ID's associated with each image, I cant alter the xml. Therefore I was wondering if there was a way in xslt to add an ID attribute to each image before it is outputted to the browser? As I want to be able to control each element/image individually using CSS.

I hope that makes sense?

The xslt is as follows.

    <xsl:for-each select=" cars/car_type">

   <!-- <h5> <xsl:value-of select="car-type"/> </h5> -->

 <div class ="images">   
 <img>
  <xsl:attribute name="src">
    <xsl:value-of select="image"/>

  </xsl:attribute>
</img>
 </div>
    </xsl:for-each>

Thanks again.

You can use generate-id ( http://www.w3.org/TR/xslt#function-generate-id ) function to generate an id for an input node eg

<xsl:for-each select="cars/car_type">
  <div class="images">
    <img src="{image}" id="{generate-id(image)}"/>
  </div>
</xsl:for-each>

When you create the CSS elsewhere in your stylesheet you simply need to make sure you process the image elements again and use generate-id again.
