Flat file data mapping to sibling nodes - xslt

Question

I have a flat file coming in where each record is a customer and it has a shipto and billto address in that record. The output schema has a customer record with an address child node. I don't know how to map the 2 addresses from the incoming record to sibiling child nodes of the customer record.
I have an input file that is defined like:
<customer>
<customernum/>
<shipaddrcity/>
<shipaddrstate/>
<shipaddrzip/>
<billaddrcity/>
<billaddrstate/>
<billaddrzip/>
</customer>
The output needs to end up looking like:
<customer>
<customernum/>
<addr>
<type/>
<city/>
<state/>
<zip/>
</addr>
<addr>
<type/>
<city/>
<state/>
<zip/>
</addr>
</customer>
I'm quite new to biztalk and have been unable to find any decent examples of how to complete this using the Biztalk Mapper. I'm also willing to listen to how to do this with xslt.

Answer 1

You probably want something specific to BizTalk, and I don't know anything about BizTalk, but this might be helpful to you any way.
Given an input document of ...
<customers>
<customer>
<customernum>1</customernum>
<shipaddrcity>Cairns</shipaddrcity>
<shipaddrstate>QLD</shipaddrstate>
<shipaddrzip>b</shipaddrzip>
<billaddrcity>Sydney</billaddrcity>
<billaddrstate>NSW</billaddrstate>
<billaddrzip>c</billaddrzip>
</customer>
<customer>
<customernum>2</customernum>
<shipaddrcity>d</shipaddrcity>
<shipaddrstate>WA</shipaddrstate>
<shipaddrzip>e</shipaddrzip>
<billaddrcity>Melbourne</billaddrcity>
<billaddrstate>Vic</billaddrstate>
<billaddrzip>f</billaddrzip>
</customer>
</customers>
... this XSLT 1.0 stylesheet ...
<xsl:transform
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
<xsl:output omit-xml-declaration="yes" encoding="UTF-8" indent="yes" />
<xsl:strip-space elements="*" />
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="customer">
<xsl:copy>
<xsl:apply-templates select="#*|node()[not(
self::shipaddrstate|
self::shipaddrzip |
self::billaddrstate|
self::billaddrzip )]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="shipaddrcity">
<addr>
<type>ship</type>
<city><xsl:value-of select="." /></city>
<xsl:apply-templates select="../(shipaddrstate|shipaddrzip)" />
</addr>
</xsl:template>
<xsl:template match="billaddrcity">
<addr>
<type>bill</type>
<city><xsl:value-of select="." /></city>
<xsl:apply-templates select="../(billaddrstate|billaddrzip)" />
</addr>
</xsl:template>
<xsl:template match="shipaddrstate|billaddrstate">
<state><xsl:value-of select="." /></state>
</xsl:template>
<xsl:template match="shipaddrzip|billaddrzip">
<zip><xsl:value-of select="." /></zip>
</xsl:template>
</xsl:transform>
... when applied to the input document, will yield ...
<customers>
<customer>
<customernum>1</customernum>
<addr>
<type>ship</type>
<city>Cairns</city>
<state>QLD</state>
<zip>b</zip>
</addr>
<addr>
<type>bill</type>
<city>Sydney</city>
<state>NSW</state>
<zip>c</zip>
</addr>
</customer>
<customer>
<customernum>2</customernum>
<addr>
<type>ship</type>
<city>d</city>
<state>WA</state>
<zip>e</zip>
</addr>
<addr>
<type>bill</type>
<city>Melbourne</city>
<state>Vic</state>
<zip>f</zip>
</addr>
</customer>
</customers>
