Production Issue! Patient Vitals Documentation: XSL Transform

Last week there was serious production issue that I had to fix. The issue was patients acute (critical) vital signs were not showing up on patient documentation.

The analyst found out acute vital signs would not show up if there was more than one set of acute vital signs. In their testing, they found out if you only have one set of acute vital signs then the acute vital signs would show up.

Here's a very simple diagram of how Emergency Documentation system flows:

Database <---> dll <---> web service <--->   .Net website

I had a lot of places to look.

I found a method that had an XML transform. This transform was converting XML returned by a stored procedure into HTML.  In debugging the web application I determined that the acute vitals data 'went missing' in the code below.

Code from private method in web service:

 XmlReader reader = XmlReader.Create(new StringReader(xml));
                StringBuilder output = new StringBuilder();
                XmlWriter writer = XmlWriter.Create(output);
                XslCompiledTransform Xsl = new XslCompiledTransform();
                Xsl.Load(xslFile);
                Xsl.Transform(reader, writer);
                html = output.ToString(0, output.Length);
                return html.Substring(html.IndexOf("));


For XML clause in the select statement from the stored procedure:
 FOR XML PATH('Vitals'),root('Visit')




I needed a lesson in XSLT but first I had to understand the business rules.
The users did not want to see any acute vital column headers in the patient documentation if there was no acute vitals taken.  Examples below:
Vitals Table without Acute Data

Vitals Table with Acute Data













A team leader here told me the XSL file could have a bug in it. He also said that I could debug these XSL files in Visual Studio. I did some online research to find out what XSL files and what transforming is. XML transforms is a way of converting XML data to: Another XML, HTML, or other text. I can see how handy this would be.  




In debugging the XSL I found that there was a variable called accuteV.  If this variable contained the value of "on" then the extra acute columns would be rendered in the html output. This variable was being set in a For-Each statement. While debugging, I noticed  if there was more than one row being returned with acute data, the accuteV variable would no longer contain any value. It was like accuteV went out of scope!

I did more online research and found out that variables in XSLT are immutable!  They can only be assigned to once. Turns out that XSLT is a function language.  The original developer had treated this as a procedural language. 

This bug of assigning a value to a variable within a For-Each explained why acute data would show up when there was only one row of acute data, but would disappear if more than one row of acute data. 

A very strange bug is very easily explained with some knowledge of how XLST works.

Now knowing the exact problem the challenge was to fix it quickly with little code changes as possible. 

I tried a few workarounds with setting the variable   The goal was not to change any other part of the XSL. I wanted all the existing code to remain the same. I did not have time to become a XSL expert and did not want to take ownership of this file either.  I tried to add  an 'and' to the if statement checking if acuteV was all ready 'on'.  I also tried to store the sum of the lengths of the acute nodes in question.  Neither of these worked.  I was stuck. 

Lucky for me the same team leader who had lead me to the XSL was working on this as well.  His found a solution to find out if there's any acute data anywhere in the XML, and only assign 'on' to acuteV once.  This solution worked like a charm!  Big Thank yous were given and Hi Fives all around.

Original XLS snip:
<xsl:variable name="acuteV" >
    <xsl:for-each select="Visit/Vitals/Acute">
      <xsl:if test="string-length(Aline)>0 or string-length(CVP)>0 or string-length(ICP)>0 or string-length(ET)>0 or string-length(FI)>0">
