RE: Dynamically setting the text of an added element in a pipeline . . ?

If I understood your example correctly, you want to iterate to iterate over a sequence of documents, and insert the "field" element in each of them. In your original source, the "source" primary input port if p:identity was automatically bound to the "current" port of p:for-each, because p:insert was the first step of the sub-pipeline. However, with the addition of p:string-replace/p:template, p:identity needs to use an explicit binding to the "current" port of p:for-each otherwise it would use the result of the p:string-replace/p:template as the source.

Hi,

Just a general question. When UploadInGroups, the name of the for-loop is the source pipe for the p:insert within the for-loop what is this doing?

       <p:input port="source">
        <p:pipe step=" UploadInGroups" port="current"/>
      </p:input>


-----------
<p:for-each name="UploadInGroups">
  <p:template name="create-field">
    <p:input port="template">
      <p:inline>
        <field name="iterationCount">$pos</field>
      </p:inline>
   </p:input>
    <p:with-param name="pos" select="p:iteration-position()"/>
  </p:template>
  <p:insert position="last-child" match="/add/doc" name="insertCounter">
      <p:input port="source">
        <p:pipe step=" UploadInGroups" port="current"/>
      </p:input>
      <p:input port="insertion">
        <p:pipe step="create-field" port="result"/>
      </p:input>
    </p:insert>
    . . .
</p:for-each>
