Uncaught TypeError: Cannot read property '0' of undefined

[ppazos]

My XML looks like this:

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="CDA.xsl"?>
<ClinicalDocument xmlns="urn:hl7-org:v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:voc="urn:hl7-org:v3/voc" xsi:noNamespaceSchemaLocation="https://raw.githubusercontent.com/ppazos/cabolabs-cda/master/CDA_flat.xsd">
  <typeId root="2.16.840.1.113883.1.3" extension="POCD_HD000040" />
  <id root="412bdccb-1c18-4b43-8184-4b2210123455" />
...

When I try to type a tag, this error appears:

events.js:160
