If you are having trouble processing XML files in Iguana, the following tips may be helpful to you:

• Ensure that the XML file specifies the character encoding that is being used. This character encoding information normally appears as the first line of the XML file:

<?xml version="1.0" encoding="UTF-8"?>

• When you define a VMD file in the Filter component of a channel to perform XML to HL7 translation, this VMD file can only process XML input that is UTF-8 or ASCII encoded. XML files that are encoded in ISO-8859-1 format (ISO-Latin-1) may not yield the output that you are expecting.

For example, consider the following sample segment, which is generated from an XML file in ISO-8859-1 format:

FT1|4|1|Incoming|200701240000^200701240000|200701251212|CG|Passé|Call as soon as possible||1||||||ABC||||4004^Smith^ John|

In this sample segment, notice that the eighth field contains some unexpected characters. This is because the HL7 output message is generated in UTF-8 format. For best results, ensure that the XML input is in UTF-8 or ASCII format.
