Nodes in an XML document

Question

I have designed a xml schema to parse an incoming xml document. The receive location gets xml documents from 2 feeds, one of them has misspelled a node in the document, "Roookie" instead of "Rookie", Is there a way to have my existing xsd parse this document?

Answer 1

You would need to replace the elements in the document or modify the xsd to work with the new document format.

Answer 2

Just modify your schema to accept a choice between 2 nodes (Rookie or Roookie) instead of simply 1 node named Rookie. Both nodes have the same type. Of course, if Roo(o)kie has a complex contents, you'll want to declare a complex type for this contents in order to avoid duplicating the whole structure of the 2 elements.

Answer 3

You could probably preprocess the wrong XML file, like with this simple XSL stylesheet:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;

<xsl:output method="xml" indent="no"/>

<xsl:template match="Roookie">
        <Rookie>
                <xsl:apply-templates select="@*|node()" />
        </Rookie>
</xsl:template>

<xsl:template match="@*|node()" name="defaultRule">
        <xsl:copy>
                <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
</xsl:template>

</xsl:stylesheet>

Answer 4

The onyl answer here is to modify the bad message. The xsd is a contract and should be adhered to by submitting systems. If you don't have this kind of control over the submitting systems, I'd suggest making a second schema with a new name and have it accomodate the spelling error. I fyou start altering your contract/xsd for every mistake in a message, you will increase complexity and decrease maintainability.
