i suggest in 2 steps:
first, apply following stylesheet "external file":
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/xsl/transform" xmlns:axsl="http://www.w3.org/1999/xsl/transformalias"> <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/> <xsl:strip-space elements="*"/> <xsl:namespace-alias stylesheet-prefix="axsl" result-prefix="xsl"/> <xsl:template match="/root"> <axsl:stylesheet version="2.0"> <axsl:template match="@*|node()"> <axsl:copy> <axsl:apply-templates select="@*|node()"/> </axsl:copy> </axsl:template> <xsl:apply-templates select="tofind"/> </axsl:stylesheet> </xsl:template> <xsl:template match="tofind"> <axsl:template match="{.}"> <xsl:apply-templates select="following-sibling::toreplace[1]/*"/> </axsl:template> </xsl:template> <xsl:template match="toreplace/*"> <xsl:copy> <xsl:copy-of select="@*"/> <axsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> the result in example be:
<?xml version="1.0" encoding="utf-8"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/xsl/transform" version="2.0"> <xsl:template match="@*|node()"> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> <xsl:template match="aside/p"> <p class="aside_para"> <xsl:apply-templates select="@*|node()"/> </p> </xsl:template> <xsl:template match="aside[@class="sidenote1"]/p"> <p class="aside_para1"> <xsl:apply-templates select="@*|node()"/> </p> </xsl:template> <xsl:template match="body/p"> <p class="body_para"> <xsl:apply-templates select="@*|node()"/> </p> </xsl:template> <xsl:template match="body/div/div/h1"> <p class="body_h_2"> <xsl:apply-templates select="@*|node()"/> </p> </xsl:template> <xsl:template match="body/div/div/div/h1"> <p class="body_h_3"> <xsl:apply-templates select="@*|node()"/> </p> </xsl:template> </xsl:stylesheet> this result xslt stylesheet of own. applying input example produce following result:
<?xml version="1.0" encoding="utf-8"?><article> <body> <p class="body_para">the body para1</p> <aside><p class="aside_para">aside para1</p></aside> <aside class="sidenote1"><p class="aside_para1">aside para2</p></aside> <div><div class="special"><p class="body_h_2">the heading1</p></div></div> <div><div><div><p class="body_h_3">the heading2</p></div></div></div> </body> </article> note of these rules ambiguous. there dangers undertake when farm out process of producing xslt external agents.
