Call for feedback : Update extensions

[Eric van der Vlist <vdv@xxxxxxxxxxxx>]

Hi,

We would like to get your thoughts about the update extensions we are
considering for prototyping our XML Server project
(http://www.egroups.com/group/xml-server/info.html) ...

The basic update statement I suggest (to update the source DOM) is :

  <xslql:update
    match = pattern 
    select = expression>
  <!-- Content: template -->
  </xslql:template> 

where pattern and expression are regular XPath patterns and expressions.

This statement would update all the nodes matching the match pattern
with either the expression of the select statement or the Content
(unlike the xsl:variable statement, the content would be considered as a
node set, not as a result tree fragment).

An example of use could be :

  <xsl:template match="place[normalize-space(text())='russia']">
    <xslql:update match="name[text()='Pete1']">
      <name>Eric</name>
    </xslql:update>
  </xsl:template>

Does it make sense ?

Would you rather suggest an alternative syntax ?

Do you have any comments of advises to give us for its implementation on
top of a XSLT processor ?

Thanks for sharing your thoughts.

Eric
