C# Class

CCR.cs contains C# classes to manipulate Continuity of Care Record (CCR) documents. It was generated using xsd.exe, the CCR.xsd file and some instructions at http://medbi.blogspot.com/2008/02/creating-c-bindings-for-ccr-and-ccd.html.

CCRTest.cs is an example program that prints out the medications in a sample CCR file (ccrsample_Allscripts.xml)

Example:

using CCR;

static void Main(string[] args)
{
	ContinuityOfCareRecord ccr = Deserialize<ContinuityOfCareRecord>(@"ccrsample_Allscripts.xml");

	Console.WriteLine("CCRDocumentObjectID = {0}", ccr.CCRDocumentObjectID);

	foreach(var medication in ccr.Body.Medications)
		Console.WriteLine(medication.Product[0].ProductName.Text);
}

XSL Transform

ccr.xsl is a modified version of AAFP's XSL file that renders dates better. In the AAFP XSLT file, ISO-8601 dates like "2010-06-19" render as "Jan 01, 2010". This modified XSLT renders dates correctly: ("Jun 19, 2010").

The diff looks vast, but changes are solely the result of pasting in the exact code from date.format-date.template.xsl. Once the XML is normalized, the diff boils down to:

1960c1960,1962
-                 <xsl:value-of select="$tz"/>
---
+                 <xsl:if test="(substring($tz, 1, 1) = '-' or substring($tz, 1, 1) = '+') and substring($tz, 4, 1) = ':'">
+                   <xsl:value-of select="$tz" />
+                 </xsl:if>
