I was tearing my hair out trying to figure out how to automatically access one tiny piece of data in a .xml file until I found this routine.

Worked on the first try for loading an OSM data file.

Warning: all XML files haven't '.xml' extension

[Wouter Falkena]

You are correct. I have removed the '.xml' extension assumption, unless the file can not be found. The update file is currently under review by MATLAB Central and should appear here soon.

Thanks v. much! I used it to read a Collada file (geometry file Google Sketch-up). Worked like a charm!

[Joao Henriques]

Simple and works pretty well! The structures are a bit verbose but they're supposed to be parsed by my program anyway; any attempts to collapse some of the nested structures would only slow down the code (some similar submissions do this but are much slower). Thanks!

[Bernard]

Thanks a lot! I finally came across a tool that can extract info from a ISO19115/19139 xml file.

[Mark]

Thanks, your auto field naming system worked great for me to work with data parsed out from XML files.

[Adrian Wanner]

Thanks for your work.
You might want to speed up the attribute parsing by about 40% by replacing lines 152-154 by the following:
str=theAttributes.item(count-1).toString.toCharArray()';
k=strfind(str,'=');
attr_name = regexprep(str(1:(k(1)-1)),'[-:.]','_');
attributes.(attr_name) =str((k(1)+2):(end-1));

[Wouter Falkena]

Thank you for this suggestion Mr. Wanner. I have updated the file and it is currently under review by the MATLAB Central. It will appear here shortly.

Works great for small files. I tested it for some larger files with >100000 entries and this takes around 178 seconds.

Excellent! I was pulling my hair to read to numbers from XML file and with this I did it in one minute

[Ivan Smirnov]

One of the problems that I personally encountered is that xml2struct can't handle CDATA blocks.

It can be easily fixed, replace line 67 with:
            if (~strcmp(name,'#text') && ~strcmp(name,'#comment') && ~strcmp(name,'#cdata_dash_section'))
and line 94 with:
            elseif (strcmp(name,'#text') || strcmp(name, '#cdata_dash_section'))

Works great otherwise, thanks.
