Setting variable explicitly using Net::SNMP works, but assigning through another variable does not

c has asked for the wisdom of the Perl Monks concerning the following question:

I am getting a peculiar error when using Net::SNMP and sending a community string to a remote device.

[2 extra after iSEQ]C=private [asnlen? 26<32] (DF)

I'm not sure what the 2 extra is referring to.The variable is being set via:

## set the v1/2c specific session traits $snmp_options{community} = $xml->{node}->{$args->{host}}->{snmp}->[0]- +>{community}->[0] || $xml->{snmp}->[0]->{community}->[0];

however, when I remove the entry from xml file and let the value be set explicitly, such as in...

## set the v1/2c specific session traits $snmp_options{community} = $xml->{node}->{$args->{host}}->{snmp}->[0]- +>{community}->[0] || $xml->{snmp}->[0]->{community}->[0] || "private";

All works well and the community is sent correctly. I've tried chop/chomping the $xml value to see if a newline might be causing the issue.

My XML file is pretty straightforward since it is just for testing

<global> <node id="router"> <snmp> <version>1</version> <retries>1</retries> <wait>5.0</wait> <mtu>1500</mtu> <debug>0</debug> <community>private</community> </snmp> <tftp> <server>10.6.21.230</server> </tftp> </node> </global>

My gut reaction is to think that there must be something wrong with the XML file, but I just dont see anything incorrect with it. Would there be something be conveyed though the XML variable that I am missing?

thanks -c
