Re: JScript error handling in msxsl ?

/ Dave Carlson <dcarlson@xxxxxxxxxxxxxx> was heard to say:
| See the example below.  In Microsoft's MSXSL processor, the getAttribute()

You can use style rules if the attributes are inherited.  This
at least reduces the proliferation of rules to an arithmetic
rather than combinatorial explosion.

I have an FOT to HTML stylesheet, it uses the following set of
style-rules and construction rules to handle paragraphs:

<style-rule>
  <target-element type="paragraph">
    <attribute name="space-before" has-value="yes"/>
  </target-element>
  <apply padding-top='=getAttribute("space-before")'/>
</style-rule>

<style-rule>
  <target-element type="paragraph">
    <attribute name="space-after" has-value="yes"/>
  </target-element>
  <apply padding-bottom='=getAttribute("space-after")'/>
</style-rule>

<style-rule>
  <target-element type="paragraph">
    <attribute name="first-line-start-indent" has-value="yes"/>
  </target-element>
  <apply text-indent='=getAttribute("first-line-start-indent")'/>
</style-rule>

<style-rule>
  <target-element type="paragraph">
    <attribute name="start-indent" has-value="yes"/>
  </target-element>
  <apply margin-left='=getAttribute("start-indent")'/>
</style-rule>

<style-rule>
  <target-element type="paragraph">
    <attribute name="color" has-value="yes"/>
  </target-element>
  <apply color='=getAttribute("color")'/>
</style-rule>

<style-rule>
  <target-element type="paragraph">
    <attribute name="font-size" has-value="yes"/>
  </target-element>
  <apply font-size='=getAttribute("font-size")'/>
</style-rule>

<style-rule>
  <target-element type="paragraph">
    <attribute name="font-weight" has-value="yes"/>
  </target-element>
  <apply font-weight='=getAttribute("font-weight")'/>
</style-rule>

<rule>
  <target-element type="paragraph"/>
  <DIV>
    <children/>
  </DIV>
</rule>

If the source instance contains

<paragraph font-size="12pt" color="#FF0000" space-before="1in">...

This transformation sheet correctly generates

<DIV style="font-size: 12pt; color: #FF0000; padding-top: 1in;">...

Some better solution will have to be found, but this works for now...

                                        Cheers,
                                          norm
