Could you please help how to split in half node with subnodes.

Input:

<RuleCollection Type="Exe" EnforcementMode="Enabled">

 <FileHashRule Id="1">

  <Conditions>

   <FileHashCondition>

    <FileHash Type="SHA256" Data="0xCC864"></FileHash>

    <FileHash Type="SHA256" Data="0x9D973"></FileHash>

    <FileHash Type="SHA256" Data="0xA92EF"></FileHash>

    <FileHash Type="SHA256" Data="0x279CD"></FileHash>

   </FileHashCondition>

  </Conditions>

 </FileHashRule>

</RuleCollection>

Output:

<RuleCollection Type="Exe" EnforcementMode="Enabled">

 <FileHashRule Id="hard-coded guid1">

  <Conditions>

   <FileHashCondition>

    <FileHash Type="SHA256" Data="0xCC864"></FileHash>

    <FileHash Type="SHA256" Data="0x9D973"></FileHash>

   </FileHashCondition>

  </Conditions>

 </FileHashRule>

 <FileHashRule Id="hard-coded guid2">

  <Conditions>

   <FileHashCondition>

    <FileHash Type="SHA256" Data="0xA92EF"></FileHash>

    <FileHash Type="SHA256" Data="0x279CD"></FileHash>

   </FileHashCondition>

  </Conditions>

 </FileHashRule>

</RuleCollection>

Unfortunatly I dont have expirience with xslt and did not find such an examples how to do it.

Updated
I tried one of the suggested approach below and have this https://xsltfiddle.liberty-development.net/jyH9rNq/3 nodes doesn't copy

xslt:

            <?xml version="1.0" encoding="UTF-8"?>

        <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

        <xsl:output method="xml" indent="yes"/>



        <xsl:variable name="fileHash" select="/FileHashRule/Conditions/FileHashCondition/FileHash" />

        <xsl:variable name="half" select="count($fileHash) div 2" />



        <xsl:template match="/">

        <RuleCollection>

            <FileHashRule>

                <xsl:attribute name="Id">ad22d301-eb88-485d-ae1d-537790bdebfa</xsl:attribute>

                    <Conditions>



                        <FileHashCondition>

                        <xsl:copy-of select="$fileHash[position() &lt;= $half]" />



                        </FileHashCondition>

                    </Conditions>

            </FileHashRule>



                <FileHashRule>

                <xsl:attribute name="Id">ad22d301-eb88-485d-ae1d-537790bdebfb</xsl:attribute>

                    <Conditions>



                        <FileHashCondition>

                        <xsl:copy-of select="$fileHash[position() &gt; $half]" />

                        </FileHashCondition>

                    </Conditions>

            </FileHashRule>





        </RuleCollection>

        </xsl:template>



        </xsl:stylesheet>   

Output:

        <?xml version="1.0" encoding="UTF-8"?>

    <RuleCollection>

       <FileHashRule Id="ad22d301-eb88-485d-ae1d-537790bdebfa">

          <Conditions>

             <FileHashCondition/>

          </Conditions>

       </FileHashRule>

       <FileHashRule Id="ad22d301-eb88-485d-ae1d-537790bdebfb">

          <Conditions>

             <FileHashCondition/>

          </Conditions>

       </FileHashRule>

    </RuleCollection>

You could find the half point quite simply by:

<xsl:variable name="fileHash" select="/RuleCollection/FileHashRule/Conditions/FileHashCondition/FileHash" />

<xsl:variable name="half" select="count($fileHash) div 2" />

Then just create the two FileHashRule elements and use:

<xsl:copy-of select="$fileHash[position() &lt;= $half]" />

to populate the first one, and:

<xsl:copy-of select="$fileHash[position() &gt; $half]" />

for the second one.

You can start from something like (XSLT Fiddle):

<?xml version="1.0" encoding="UTF-8"?>

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

  <xsl:output method="xml" indent="yes"/>



  <xsl:template match="//xs">

    <xsl:copy>

        <xsl:apply-templates select="@*"/>

        <xsl:apply-templates select='x[position() &lt;= last() div 2]'/>

    </xsl:copy>



    <xsl:copy>

        <xsl:apply-templates select="@*"/>

        <xsl:apply-templates select='x[position() &gt; last() div 2]'/>

    </xsl:copy>

  </xsl:template>



  <xsl:template match="@* | node()">

      <xsl:copy>

        <xsl:apply-templates select="@* | node()"/>

      </xsl:copy>

  </xsl:template>



</xsl:stylesheet>

It will split

<?xml version="1.0" encoding="utf-8" ?>

<data>

    <xs a="b">

        <will-not-be-copied/>

        <x>1</x>

        <x>2</x>

        <x>3</x>

        <x>4</x>

    </xs>

</data>

into

<?xml version="1.0" encoding="UTF-8"?>

<data>

    <xs a="b">

      <x>1</x>

      <x>2</x>

   </xs>

   <xs a="b">

      <x>3</x>

      <x>4</x>

   </xs>

</data>

Note though, that you need to clarify how you want to deal with tags like <will-not-be-copied> and you might want to add your id values to the splitted <xs> tags.

Here's one way:

<xsl:template match="@*|node()" mode="#all">

  <xsl:copy>

    <xsl:apply-templates select="@*|node()" mode="#current"/>

  </xsl:copy>

</xsl:template>



<xsl:template match="FileHashRule">

  <FileHashRule Id="{@Id}">

    <xsl:apply-templates mode="one"/>

  </FileHashRule>

  <FileHashRule Id="{@Id + 1}">

    <xsl:apply-templates mode="two"/>

  </FileHashRule>

</xsl:template>



<xsl:template match="FileHash[position() > last() div 2]" mode="one"/>

<xsl:template match="FileHash[position() &lt;= last() div 2]" mode="two"/>

The first rule says: by default, copy nodes unchanged.

The second rule says: For a FileHashRule, create two copies, incrementing the @Id attribute in the second.

The third rule says: during the first phase, skip any FileHash element in the second half of the list.

The fourth rule says: during the second phase, skip any FileHash element in the first half of the list.
