The ns0
prefix is added whenever a BizTalk btm maps a message. It shouldn't matter as this is still valid xml, however this could be a problem when sending messages to partners with legacy or incomplete xml parsers.
You can remove the ns0
prefix and instead make ns0
your default namespace on the output message by changing your btm from a visual map to an .xslt
map.
e.g. Once you have converted your map to xslt, change the xslt from:
<?xml version="1.0" encoding="utf-16"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
exclude-result-prefixes="msxsl s0"
version="1.0"
xmlns:ns0="http://targetns"
xmlns:s0="http://sourcens"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="s0:FromRoot" />
</xsl:template>
<xsl:template match="s0:FromRoot">
<ns0:ToRoot>
<xsl:for-each select="s0:FromElement">
<ns0:ToElement>
<xsl:value-of select="text()"/>
</ns0:ToElement>
</xsl:for-each>
</ns0:ToRoot>
</xsl:template>
</xsl:stylesheet>
To:
<?xml version="1.0" encoding="utf-16"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
xmlns:var="http://schemas.microsoft.com/BizTalk/2003/var"
exclude-result-prefixes="msxsl s0"
version="1.0"
xmlns="http://targetns"
xmlns:s0="http://sourcens"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<xsl:output omit-xml-declaration="yes" method="xml" version="1.0" />
<xsl:template match="/">
<xsl:apply-templates select="s0:FromRoot" />
</xsl:template>
<xsl:template match="s0:FromRoot">
<ToRoot>
<xsl:for-each select="s0:FromElement">
<ToElement>
<xsl:value-of select="text()"/>
</ToElement>
</xsl:for-each>
</ToRoot>
</xsl:template>
</xsl:stylesheet>
i.e. change the default xmlns and then remove the ns0 prefixes automatically.
A more generic solution is also possible (e.g. similar to Firras' answer here), which could be useful e.g. to place as a send port map to strip out all prefixes from elements. However, one needs to be wary if there are more than one xmlns on the output message!
