I have flat xml like this
<field name="a1"/>
<field name="a2" merge="true"/>
<field name="a3"/>
<field name="a4"/>
<field name="a5" merge="true"/>
<field name="a6" merge="true"/>
<field name="a7"/>
but I want to loop through them like this
<field name="a1">
<field name="a2" merge="true"/>
</field>
<field name="a3"/>
<field name="a4">
<field name="a5" merge="true"/>
<field name="a6" merge="true"/>
</field>
<field name="a7"/>
It means nodes with merge attribute is child of the previous node. I only
need handle one level for now, any suggestion?
You could apply an XSLT transformation to have the nested structure:
<?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="fields">
<xsl:copy>
<xsl:apply-templates select="@*" />
<xsl:apply-templates select="field[not(@merge)]" />
</xsl:copy>
</xsl:template>
<xsl:template match="field">
<xsl:copy>
<xsl:apply-templates select="@*" />
<xsl:apply-templates
select="following-sibling::field[1][@merge = 'true']" mode="child" />
</xsl:copy>
</xsl:template>
<xsl:template match="field" mode="child">
<xsl:copy>
<xsl:apply-templates select="@* | node()" />
</xsl:copy>
<xsl:apply-templates
select="following-sibling::field[1][@merge = 'true']" mode="child" />
</xsl:template>
<xsl:template match="@*">
<xsl:copy />
</xsl:template>
</xsl:stylesheet>
