This is my XML Document(Small Snippt).

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">

<w:body>

    <w:p> <!-- Current Node -->

</w:document>

Here, I want to select the following-sibling of the first<w:p> using for-each statement until it encounters the next<w:p> that having its <w:pPr><w:pStyle w:val="Heading1"/></w:pPr>.

for example,for first<w:p> i want to select only next three following-siblings.(ie,paragraph2,paragraph3 and including table info).because,4th <w:p> having <w:pPr><w:pStyle w:val="Heading1"/></w:pPr>.

The same case for 4th<w:p> if it is current node. Then i want to select only 5th <w:p>.

I dont know how to specify this condition in for-each.So, Can u guide me to get this…

My Required output is like:

<Document>
   <Heading1>
        <paragraph>paragrap1</paragraph>
        <paragraph>table info</paragraph>
        <paragraph>paragrap2</paragraph>
        <paragraph>paragrap3</paragraph>
   </Heading1>
   <Heading1>
        <paragraph>paragrap4</paragraph>
        <paragraph>paragrap5</paragraph>
   </Heading1>
   <Heading1>
        <paragraph>paragrap6</paragraph>
   </Heading1>
</Document>

Answer 1

Here, I want to select the following-sibling of the first <w:p>
using for-each statement until it encounters the next <w:p> that
having its <w:pPr><w:pStyle w:val="Heading1"/></w:pPr>.

This XSLT 2.0 transformation shows one way of doing it using the XPAth 2.0 operator >>:

<xsl:stylesheet version="2.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:xs="http://www.w3.org/2001/XMLSchema"
 xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"
  exclude-result-prefixes="w xs">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="*/w:p[1]">

  <xsl:variable name="vNextWP" select=
  "following-sibling::w:p
    [w:pPr/w:pStyle/@w:val='Heading1']
     [1]
  "/>

  <xsl:copy-of select=
  "following-sibling::w:p[$vNextWP >> .]"/>
 </xsl:template>

 <xsl:template match="text()"/>
</xsl:stylesheet>

when applied on the provided XML document:

<w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">

    <w:body>

        <w:p> <!-- Current Node -->
            <w:pPr>
                <w:pStyle w:val="Heading1"/>
            </w:pPr>

            <w:r>
                <w:t>
                     Paragraph1
                </w:t>
            </w:r>
        </w:p>

        <w:p>
            <w:pPr>
            </w:pPr>
            <w:r>
                <w:t>
                     Paragraph2
                </w:t>
            </w:r>
        </w:p>

        <w:p>
            <w:pPr>
            </w:pPr>
            <w:r>
                <w:t>
                     Paragraph3
                </w:t>
            </w:r>
        </w:p>

        <w:p>
            <w:pPr>
                <w:pStyle w:val="Heading1"/>
            </w:pPr>

            <w:r>
                <w:t>
                     Paragraph4
                </w:t>
            </w:r>
        </w:p>

        <w:p>
            <w:pPr>
            </w:pPr>
            <w:r>
                <w:t>
                     Paragraph5
                </w:t>
            </w:r>
        </w:p>

        <w:p>
            <w:pPr>
                <w:pStyle w:val="Heading1"/>
            </w:pPr>

            <w:r>
                <w:t>
                     Paragraph6
                </w:t>
            </w:r>
        </w:p>

    </w:body>
</w:document>

exactly the wanted nodes are selected and copied to the output:

<w:p xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
            <w:pPr>
            </w:pPr>
            <w:r>
                <w:t>
                     Paragraph2
                </w:t>
            </w:r>
        </w:p>
<w:p xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">
            <w:pPr>
            </w:pPr>
            <w:r>
                <w:t>
                     Paragraph3
                </w:t>
            </w:r>
        </w:p>

Update: The OP has clarified what wanted the result of the transformation is (grouping), so here is:

I. XSLT 1.0 solution:

 <xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"
 exclude-result-prefixes="w">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:key name="kFollowing"
  match="w:p[not(w:pPr/w:pStyle/@w:val = 'Heading1')]
        |
         w:tbl"
  use="generate-id(preceding-sibling::w:p
           [w:pPr/w:pStyle/@w:val = 'Heading1'][1])
  "/>

 <xsl:template match="/*">
  <Document>
   <xsl:apply-templates/>
  </Document>
 </xsl:template>

 <xsl:template match=
 "w:p[w:pPr/w:pStyle/@w:val = 'Heading1']">

  <Heading1>
   <xsl:apply-templates mode="inGroup" select=
    ". | key('kFollowing', generate-id())"/>
   </Heading1>
 </xsl:template>

 <xsl:template match="*" mode="inGroup">
  <paragraph>
    <xsl:value-of select="normalize-space(.//w:t)"/>
  </paragraph>
 </xsl:template>

 <xsl:template match="w:body/*" priority="-1"/>
</xsl:stylesheet>

when this transformation is applied on the newly provided XML document:

<w:document xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main">

<w:body>

    <w:p> <!-- Current Node -->
        <w:pPr>
            <w:pStyle w:val="Heading1"/>
        </w:pPr>

        <w:r>
            <w:t>
                 Paragraph1
            </w:t>
        </w:r>
    </w:p>

    <w:tbl>
        <w:t>table info
        </w:t>
    </w:tbl>

    <w:p>
        <w:pPr>
        </w:pPr>
        <w:r>
            <w:t>
                 Paragraph2
            </w:t>
        </w:r>
    </w:p>

    <w:p>
        <w:pPr>
        </w:pPr>
        <w:r>
            <w:t>
                 Paragraph3
            </w:t>
        </w:r>
    </w:p>

    <w:p>
        <w:pPr>
            <w:pStyle w:val="Heading1"/>
        </w:pPr>

        <w:r>
            <w:t>
                 Paragraph4
            </w:t>
        </w:r>
    </w:p>

    <w:p>
        <w:pPr>
        </w:pPr>
        <w:r>
            <w:t>
                 Paragraph5
            </w:t>
        </w:r>
    </w:p>

    <w:p>
        <w:pPr>
            <w:pStyle w:val="Heading1"/>
        </w:pPr>

        <w:r>
            <w:t>
                 Paragraph6
            </w:t>
        </w:r>
    </w:p>

</w:body>
</w:document>

the wanted, correct result is produced:

<Document>
   <Heading1>
      <paragraph>Paragraph1</paragraph>
      <paragraph>table info</paragraph>
      <paragraph>Paragraph2</paragraph>
      <paragraph>Paragraph3</paragraph>
   </Heading1>
   <Heading1>
      <paragraph>Paragraph4</paragraph>
      <paragraph>Paragraph5</paragraph>
   </Heading1>
   <Heading1>
      <paragraph>Paragraph6</paragraph>
   </Heading1>
</Document>

II. XSLT 2.0 solution:

<xsl:stylesheet version="2.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:w="http://schemas.openxmlformats.org/wordprocessingml/2006/main"
  exclude-result-prefixes="w"   >
    <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/*">
     <Document>
      <xsl:for-each-group
      select="*/*"
      group-starting-with="w:p[w:pPr/w:pStyle/@w:val = 'Heading1']">
       <Heading1>
         <xsl:for-each select="current-group()//w:t">
           <paragraph>
             <xsl:sequence select="normalize-space(.)"/>
           </paragraph>
         </xsl:for-each>
       </Heading1>
      </xsl:for-each-group>
     </Document>
 </xsl:template>
</xsl:stylesheet>

when this XSLT 2.0 transformation is applied on the same XML document (above), the same wanted, correct result is produced:

<Document>
   <Heading1>
      <paragraph>Paragraph1</paragraph>
      <paragraph>table info</paragraph>
      <paragraph>Paragraph2</paragraph>
      <paragraph>Paragraph3</paragraph>
   </Heading1>
   <Heading1>
      <paragraph>Paragraph4</paragraph>
      <paragraph>Paragraph5</paragraph>
   </Heading1>
   <Heading1>
      <paragraph>Paragraph6</paragraph>
   </Heading1>
</Document>
