Extracting specific file from zip in matlab

问题

Currently I have a zipfile containing several thousand .xml files, extracted the folder is 1.5gb in size. I have a function that matches data with specific files inside this zip file. I then want to read this specific file and extract additional data.

My question: Is there any way to extract these specific files from the archive without unzipping the entire archive?

The built in unzip.m function can only be used to unzip the entire file so it won't work so I am thinking I have to use the COM interface or some other approach.

Matlab version: R2013a

While searching for solutions I found this:Read the data of CSV file inside Zip File without extracting the contents in Matlab

But I can't get the code in the answer to work for my situation

Edit:

zipFilename = 'HMDB.zip';
zipJavaFile = java.io.File(zipFilename);
zipFile=org.apache.tools.zip.ZipFile(zipJavaFile);
entries=zipFile.getEntries;
cnt=1;
while entries.hasMoreElements
    tempObj=entries.nextElement;
    file{cnt,1}=tempObj.getName.toCharArray';
    cnt=cnt+1;
end
ind=regexp(file,'$*.xml$');
ind=find(~cellfun(@isempty,ind));
file=file(ind);
file = cellfun(@(x) fullfile('.',x),file,'UniformOutput',false);

And not forgetting the

zipFile.close
