At the BBC f2f we considered adding a 'word' level selector to XPath, so
the example might become:

<style>
  p { display : none; color: blue }

</style>

<animations>
  <animation id="a1">
    <set attributeName="display" to="auto"/>
  </animation>

  <animation id="a2">
    <set attributeName="color" to="red"/>
  </animation></animations>

<par>

  <cue select="id(p1)" use="a1"/>

  <seq>

    <cue select="p1/word(1)" use="a2" dur="1"/>

    <cue select="p1/word(2)" use="a2" dur="1"/>

    <cue select="p1/word(3))" use="a2" dur="1"/>

    <cue select="p1/word(4)" use="a2" dur="1"/>

    <cue select="p1/word(5)" use="a2" dur="1"/>

    <cue select="p1/word(6)" use="a2" dur="1"/>

  </seq>

</par>

</par>

<p id="p1">

  Scooby dooby doo where are you?

</p>

 

However what word is defined as (e.g. some sort of regular expression),
might be highly language sensitive.

 

 

On another topic in this thread, the notion of fitting a too long
caption in a fixed size box, one approach might be some temporal
additions to the CSS2 overflow property.

f rom content

 

Glenn,

 

	The last cue does not select content because I want the
animation to affect the content already selected by the previous two
cues.

		 

		GA: this would still require selecting content. It would
be awkward to have an implicit selection.

		 

		[JB> ] I don't have a problem with selecting the content
- I can see how implicit slection could cause complications witrh
inherited style etc.

 

in your example reproduced below....

 

<style>
  p { display : none; color: blue }

</style>

<animations>
  <animation id="a1">
    <set attributeName="display" to="auto"/>
  </animation>

  <animation id="a2">
    <set attributeName="color" to="red"/>
  </animation></animations>

<par>

  <cue select="id(p1)" use="a1"/>

  <seq>

    <cue select="id(w1)" use="a2" dur="1"/>

    <cue select="id(w2)" use="a2" dur="1"/>

    <cue select="id(w3)" use="a2" dur="1"/>

    <cue select="id(w4)" use="a2" dur="1"/>

    <cue select="id(w5)" use="a2" dur="1"/>

    <cue select="id(w6)" use="a2" dur="1"/>

  </seq>

</par>

</par>
...

<p id="p1">

  <span id="w1">Scooby</span>

  <span id="w2">dooby</span>

  <span id="w3">doo</span>,

  <span id="w4">where</span>

  <span id="w5">are</span>

  <span id="w6">you</span>?

</p>

 

Can we dispense with the spans, i.e. is there a way that the select can
extract from a single element. BTW Your spans lost the whitespace -
unless there is some assumed mechanism for re-inserting it?.

 

<p id="p1">

  Scooby dooby doo where are you?

</p>
