ERROR: expected one child, during creating a new case

Hello
I was troubled in porting CESM on a new server, since I was following the tutorial from Yonas (Installing, Porting & Running Community Earth System Model). But one error occurred since I started creating the new case, as shown below:

fuhao@tian-09:~/cesm/cime/scripts$ ./create_newcase --case /home/fuhao/cesm/scratch/test --compset QPC4 --res f45_f45_mg37 --run-unsupported
Compset longname is 2000_CAM40_SLND_SICE_DOCN%AQP3_SROF_SGLC_SWAV
Compset specification file is /home/fuhao/cesm/cime/../components/cam//cime_config/config_compsets.xml
Compset forcing is 1972-2004

ROF component is Stub river component
GLC component is Stub glacier (land ice) component
WAV component is Stub wave component
ESP component is
Pes specification file is /home/fuhao/cesm/cime/../components/cam//cime_config/config_pes.xml
Compset specific settings: name is SSTICE_DATA_FILENAME and value is $DIN_LOC_ROOT/atm/cam/sst/sst_HadOIBl_bc_1x1_2000climo_c180511.nc
Machine is tian-09
ERROR: Expected one child

I also checked the question from mc Zhao (ERROR: Expected one child), but it's not suitable for my error, and I even don't know where this error oringed from.

So, please give me some advice on solving this problem, the files for machine and compilers defining are attached.

I think there is an error in your XML files. Although when I looked at them I didn't see an obvious error. But, I recommend for example using the UNIX tool "xmllint" to see if the XML is valid. There might also be a problem with your file following our standard, so if the XML is valid, you should also use our XSD
files which are under "cime/CIME/data/config/xml_schemas/" for recent versions of the model.

Some additional help on porting CESM is in the cime documentation here:

Dear Erik, thanks for your suggestion.

I keep checking the .xml file through the .xsd file each time I have corrected the .xml file. I reconfirmed the config_compilers.xml file, and it won't work while I set the variables' path started with $HOME, even under the circumstance that I had defined the $HOME in the bash, it went on after I set the full path.

OK, if I understand what you are saying you got it to work if you use a full path, but using "$HOME" as a variable in the xml file didn't. I actually wouldn't expect it to be able to use $HOME in this context, so I think you will have to provide the whole path here.
