[jsdl-wg] (Param Sweep) artf6147 : Explanation for matching on part of element content

[geoff]

Hi all,

Would like to propose a modification of the [2.3 [parameter]] content in 
the draft along the following lines.

1) Addition at the point of introduction of XPath use of the following 
links for referencing XPath nomenclature:

   XPath 1.0 : http://www.w3.org/TR/xpath
   XPath 2.0 : http://www.w3.org/TR/xpath20/

2) Insertion of a second example (e.g. a new [2.3.3]) to illustrate use 
of substring function:

The following example illustrates the ability to match on part of an 
element content through the use of the XPath 1.0 substring function:

<jsdl:JobDefinition>
   <jsdl:JobDescription>
     <jsdl:Application>
       <jsdl-posix:POSIXApplication>
         <jsdl-posix:Executable>/bin/some_exe</jsdl-posix:Executable>
         <jsdl-posix:Argument>-infile</jsdl-posix:Argument>
         <jsdl-posix:Argument>in.NNN.dat</jsdl-posix:Argument>
       </jsdl-posix:POSIXApplication>
     </jsdl:Application>
   </jsdl:JobDescription>
   <sweep:Sweep>
     <sweep:Assignment>
       <sweep:Parameter>
         substring(/*//jsdl-posix:Argument[2], 4, 3)
       </sweep:Parameter>
       <sweepfunc:Values>
         <sweepfunc:Value>001</sweepfunc:Value>
         <sweepfunc:Value>002</sweepfunc:Value>
         <sweepfunc:Value>003</sweepfunc:Value>
         <sweepfunc:Value>004</sweepfunc:Value>
         <sweepfunc:Value>005</sweepfunc:Value>
       </sweepfunc:Values>
     </sweep:Assignment>
   </sweep:Sweep>
</jsdl:JobDefinition>

The above yields the following 5 jobs:

"-infile in.001.dat"
"-infile in.002.dat"
"-infile in.003.dat"
"-infile in.004.dat"
"-infile in.005.dat"


Note: I've referred to the substring function as "XPath 1.0" (unlike the 
draft which implies in the footer that it's an XPath 2.0 function) as 
it's XPath 1.0 that defines its use. Not sure if this is important.

3) For the benefit of the less attentive reader, perhaps the use of 
emphasis e.g. bold (or titled as "Invalid Example 1") to stress that the 
existing [2.3.3  Example 2] represents an invalid form.
