Use node.setNodeValue() to set the value of a leaf node, works for all node types
Source Code
local Msg = hl7.message{vmd='demo.vmd', name='ADT'}
-- NO BENEFIT: set the Time in the MSH segment
Msg.MSH[7][1] = os.date('%Y%m%H%m') -- works: assigns value to the child node
Msg.MSH[7][1]:setNodeValue(os.date('%Y%m%H%m')) -- works: set the node value
-- BENEFIT: if you decide to use a variable
local MsgTime = Msg.MSH[7][1]
MsgTime:setNodeValue(os.date('%Y%m%H%m')) -- works: set the node value
MsgTime = os.date('%Y%m%H%m') -- fails: assigns the date to the variable (try it)
Description
Use node.setNodeValue() to set the value of a leaf node, works for all node types
Usage Details
Use node.setNodeValue() to set the value of a leaf node. Often assignment works instead (and is more succinct), however there are occasions when using node.setNodeValue() is useful, for example if you place a node into a variable (see the sample code).
Note: The node.setNodeValue() function works with all types of node trees.
How to use the snippet:
- Paste the code into your script
