DICA: Formatar XML em duas linhas de COS
Se estiver manipulando XML, muitas vezes ele pode ser não formatado para exibição humana.
Usando um pouco de magia XSLT você pode formatar o XML em apenas duas linhas de código...
ClassMethod Format(pXmlStream As %CharacterStream, Output pXmlStreamFormatted As %CharacterStream) As %Status
{
set xslt=##class(%Dictionary.XDataDefinition).%OpenId(..%ClassName(1)_"||XSLT",-1,.sc)
quit ##class(%XML.XSLT.Transformer).TransformStream(pXmlStream,xslt.Data,.pXmlStreamFormatted)
}
XData XSLT
{
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:strip-space elements="*"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
}
{
set xslt=##class(%Dictionary.XDataDefinition).%OpenId(..%ClassName(1)_"||XSLT",-1,.sc)
quit ##class(%XML.XSLT.Transformer).TransformStream(pXmlStream,xslt.Data,.pXmlStreamFormatted)
}
XData XSLT

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