Re: Process map entries in defined order

Dear all,

I have a scenario with a user-defined set of substitutions which should be applied to text nodes (a.k.a. strings). The XML is built like this:

 CB CB CB CB CB CB CB  <substitute search="car" replace="auto"/>
 CB CB CB CB CB CB CB  <substitute search="auto" replace="mobile"/>

As you can see from this little example the order of replacements is important. I started with creating a map(xs:string, xs:string) for the search and replace terms. Recursively applying the substitutions uses map:keys($subs). Next, I learned from the specification that this function C"BBReturns the set of keys found in an input map, in arbitrary order.C"BB

Since I want to honor the order given by the user, I think the only way out is to change my map to include an integer key and feature the search and replace string as the entry value: map(xs:integer, xs:string+) and always sort the list of keys by number.

Or is there another smoother way handling this challenge?

Best regards,

Michael

FYI, this is the current function I am using:

 CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB  <xsl:function name="dy:applySubstitutions" as="xs:string">
 CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB  <xsl:param name="text" as="xs:string"/>
 CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB  <xsl:param name="subs" as="map(xs:string, xs:string)"/>
 CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB  <xsl:choose>
 CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB CB  <xsl:when test="/map:size/(*$subs*) eq 0">
