xml - How move Child Nodes along with values to grand parent node -

i tried few different ways transfer child nodes grand parent, pattern match happening 1 child node not recursively. appreciate here.

<grandparent1>     <parent1>         <child1>1</child1>         <child2>2</child2>     </parent2> </grandparent1> 

should become

<grandparent1>     <child1>1</child1>     <child2>2</child2> </grandparent1> 

size of child nodes varies. appreciate here

this easy using xslt's recursive processing model.

first, use identity transform template recursively copy as is. add exception parent nodes , make them continue recursion without copying themselves.

xslt 1.0

<xsl:stylesheet version="1.0"  xmlns:xsl="http://www.w3.org/1999/xsl/transform"> <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/> <xsl:strip-space elements="*"/>  <!-- identity transform --> <xsl:template match="@*|node()">     <xsl:copy>         <xsl:apply-templates select="@*|node()"/>     </xsl:copy> </xsl:template>  <xsl:template match="parent1 | parent2">     <xsl:apply-templates/> </xsl:template>  </xsl:stylesheet> 

to make generic parent (i.e. 2nd level) node, without knowing name in advance, use:

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

as second template.
