[英]Iterating through HL7 message using Segment Iterator Object of Chameleon Python API
I am generating HL7 messages using Interfaceware Iguana and Chameleon. 我正在使用Interfaceware Iguana和Chameleon生成HL7消息。 This is my first experience with Python, so this question may be immature.
这是我第一次使用Python,因此这个问题可能还不成熟。 I am trying to iterate through message using Segment Iterator Object.
我正在尝试使用Segment Iterator Object遍历消息。
current_segment = environment.input_segment_iterator()
current_segment.apply_transform()
output = current_segment.output()
if current_segment.move_next('OBX'):
log('OBX setId is ' + current_segment.field(1).value );
I have written this script in global post process equation window, but it always gives me an error saying 我已经在全局后期处理方程式窗口中编写了此脚本,但是它总是给我一个错误提示
RuntimeError: Invalid iterator must be reset before being used while calling apply_transform
while executing the outgoing post process equation for the project.
I have seen many examples of using iterator, and all follow same pattern. 我已经看到了许多使用迭代器的示例,并且都遵循相同的模式。 How do I reset this iterator, and why is this invalid?
如何重置此迭代器,为什么无效?
After doing some research work, I discovered that I cannot use input_segment_iterator
in the post process
equation window, but in transformation
window. 经过一些研究工作,我发现不能在
post process
方程式窗口中使用input_segment_iterator
,而是在transformation
窗口中使用。 Now I am able to see changes I make to script using the Test Mapping
feature of Chameleon. 现在,我可以看到使用Chameleon的“
Test Mapping
功能对脚本所做的更改。 But how can I configure this change to be implemented on each message which I generate using this vmd
? 但是,如何配置此更改以在使用此
vmd
生成的每条消息上实施?
I think someone working with INTERFACEWARE Chameleon and Iguana products could easily help me out. 我认为使用INTERFACEWARE Chameleon和Iguana产品的人员可以轻松帮助我。
Not much of an Iguana person, But what I believe is you are missing this 鬣蜥的人不多,但我相信你错过了这个
current_segment.reset()
after you are done iterating through OBX, so that it sets the current segment to MSH. 在完成对OBX的迭代之后,使用
current_segment.reset()
,以便将当前段设置为MSH。
