Default How to group repeated segment in same context
select every following segment until next sibling occurs and group them under target structure

In XSLT 2.0, use

Code:
<xsl:for-each-group select="*" group-starting-with="Item">
  <Item>
     ... item details ...
     <xsl:for-each select="current-group()[self::DeliveryInfo]">
        ... delivery details
     </xsl:for-each>
  </Item>
</xsl:for-each>
In XSLT 1.0, it's much more difficult. The simplest approach is along the lines

Code:
<xsl:for-each select="Item">
  <Item>
   ... item details ...
   <xsl:variable name="here" select="$generate-id()"/>
   <xsl:for-each select="following-sibling::DeliveryInfo[generate-id(preceding-sibling::Item[1]) = $here]">
      ... delivery details ...
   </xsl:for-each>
<xsl:for-each>
When asking XSLT questions, please always say which version you are using since the answers are often very different. Also use [ c o d e ] and [ / c o d e ] to delimit your code to make it readable.

Hi Michael:
Thank you so much for quick help however my problem is DataSet will be multiple in a single file and we need to handle context as well as correct data should be populated for example i have corrected the entire input and output structure. May I request you to please help me here.

It is hard to understand your completely unindented input and output samples but I think you can use for-each-group, as already suggested (of course assuming you use an XSLT 2 or 3 processor like Saxon 9 or Altova 2017/18/19):

Code:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
	xmlns:xs="http://www.w3.org/2001/XMLSchema"
	exclude-result-prefixes="#all"
	version="3.0">

  <xsl:mode on-no-match="shallow-copy"/>

  <xsl:output indent="yes"/>
  
  <xsl:template match="DataSet">
      <xsl:copy>
          <xsl:for-each-group select="*" group-starting-with="Item">
              <xsl:choose>
                  <xsl:when test="self::Item">
                      <xsl:copy>
                          <xsl:apply-templates select="node(), tail(current-group())"/>
                      </xsl:copy>
                  </xsl:when>
                  <xsl:otherwise>
                      <xsl:apply-templates select="current-group()"/>
                  </xsl:otherwise>
              </xsl:choose>
          </xsl:for-each-group>
      </xsl:copy>
  </xsl:template>
  
</xsl:stylesheet>

Hi Michael:
Thanks for suggestion, However I am using XSLT 1.0 prod system has limitation to only use xslt 1.0, And also I have formatted/indent test data set. May I request you to please have a look.

Thanks

I'm afraid it's over 15 years since I used XSLT 1.0 in anger and I've forgotten most of the workarounds.

And of course, it's no fun working with old technology when you know the problem is trivial to solve with something more up to date.

So I'm going to decline this one.

Sorry.

Go away, you scum. Find a way to promote your business that doesn't make your readers hate you.
