are discussed.]
Hi,
It is easy to change the class attribute on the mediaobject's div, but hard
to add one to img. In DocBook XSL, the class attribute for most elements is
generated by processing the element in mode="class.value". Of the three
elements that make up a mediaobject for a graphic, only mediaobject itself
is processed this way, so no class attribute is generated for <img>
currently.
So to change it for mediaobject's div, you can do this:
<xsl:template match="mediaobject" mode="class.value">
<xsl:choose>
<xsl:when test="@role">
<xsl:value-of select="@role"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="local-name()"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
This will result in:
<div class="informalfigure">
<div class="test2">
<img alt="alt" src="images/articles/common_law.png"/>
</div>
</div>
and you can write a CSS selector to apply it to img:
.test2 img {
}

Subject: [docbook] How to add a class attribute to a image
Hello,
I want to add a class attribute to my img tag.

<imagedata role="test4"
fileref="images/articles/common_law.png"/>
</imageobject>
<textobject><phrase>alt</phrase></textobject>
</mediaobject>
</informalfigure>
