Pubmed API: What are systemID and publicID?

The Matlab script I'd written in April 2016 to interface with the Pubmed API to automatically extract a bunch of gene info is no longer working. Something about needing both a SystemID and PublicID. Any ideas?
Simplified version of the code:
baseSearchURL = ['http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=pubmed'];
gene = 'pten';
termOptTOTAL = ['&term=', gene];
searchURL = [baseSearchURL,termOptTOTAL];
Full error message:
[Fatal Error] esearch.fcgi?db=pubmed&term=pten:1:50: White spaces are required between publicId and systemId.
Error using xmlread (line 97)
Java exception occurred:
org.xml.sax.SAXParseException; systemId: http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi?db=pubmed&term=pten; lineNumber:
1; columnNumber: 50; White spaces are required between publicId and systemId.

I use PubMed frequently, but not to do what you’re doing. When I plugged ‘http://eutils.ncbi.nlm.nih.gov/entrez/eutils/’ into the URL bar, I got ‘Page has moved here’ and was vectored to Entrez Programming Utilities Help. You might see if that page has the information you need.

It is possible to avoid XML by using webread and setting the retmode parameter to 'json'. JSON is easier to work with because webread will parse it and give you a struct.
Example:
>> result = webread('http://eutils.ncbi.nlm.nih.gov/entrez/eutils/esearch.fcgi','db','pubmed','term','pten','retmode','json')
result =
struct with fields:
header: [1×1 struct]
esearchresult: [1×1 struct]
>>
You can find some information about the retmode parameter in [1].
