ERROR: expected one child, during creating a new case

[Fuhow]

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:

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.

I met the same problem during creating the case,I can not solve it.Please see my atttached files.Thanks.
