## select.mediaobject.index

select.mediaobject.index — Selects the position of the appropriate media object from a list

## Synopsis

    <xsl:template name="select.mediaobject.index">
    <xsl:param name="olist" select="imageobject|imageobjectco                      |videoobject|audioobject|textobject"/>
    <xsl:param name="count">1</xsl:param>
      ...
    </xsl:template>

##

This template takes a list of media objects (usually the children of a mediaobject or inlinemediaobject) and determines the "right" object. It returns the position of that object to be used by the calling template.

If the parameter `use.role.for.mediaobject` is nonzero, then it first checks for an object with a role attribute of the appropriate value. It takes the first of those. Otherwise, it takes the first acceptable object through a recursive pass through the list.

This template relies on a template named "is.acceptable.mediaobject" to determine if a given object is an acceptable graphic. The semantics of media objects is that the first acceptable graphic should be used.

If no acceptable object is located, no index is returned.

## Parameters

olist

  The node list of potential objects to examine.

count

  The position in the list currently being considered by the recursive process.

## Returns

Returns the position in the original list of the selected object.
