Reply to Val Schmidt Comments:

By default xml_read is configured for most common use. If you need performance, DOMnode2struct can be sometimes significantly speeded up if you use Pref.Str2Num='never' and/or trim your output by changing Pref.ReadAttr, Pref.ReadSpec and Pref.NumLevels.

Mark: have you tried using the Pref.Str2Num=false with xml_read?

Hi,

I am using your tool very often and I want to thank you for that.

This week I found a little problem and do not knwo how to solve. First of all my xml file:
<measurement>
      <values>
        <value>
          <rssi>-90</rssi>
          <identifier>
            <name>00-11-88-87-F4-82</name>
          </identifier>
        </value>
      </values>
    </measurement>
<measurement>
      <values>
        <value>
          <rssi>-81</rssi>
          <identifier>
            <name>00-11-88-88-42-40</name>
          </identifier>
        </value>
      </values>
    </measurement>

Reading the first part is working, so I get a string called '00-11-88-87-F4-82' with the RSSI value. WIth the second part there is a problem. Because there are only numbers in the string, xmlread does not interpret it as a string. It calcluates the the value of -269. But I need it as String because it is not a number.
How can I solve the problem? Changing the name is not possible because it is given by the application where the xml is coming from.

Thank you in advance.

Kind regards

Mark Weber

I think there's some problem in this part:

digits = '[Inf,NaN,pi,\t,\n,\d,\+,\-,\*,\.,e,i, ,E,I,\[,\],\;,\,]';
s = regexprep(str, digits, ''); % remove all the digits and other allowed characters

I found this when one of my LeafNode called "IN" was recognized as "NaN".

I suggest the following modification.

>> regexprep('IN','[Inf,NaN]','')

ans =

     ''

>> regexprep('IN','(Inf)|(NaN)','')

ans =

IN

One other thing is "num = str2num(str)" is a somewhat dangerous function. I'm not sure if it worth it to use this to provide some fancy functionality.

Hmm, having problems commenting. This is what the question used to be:

VERY nice tool indeed, especially the Pref settings which let you modify the output. However, I have a problem with empty tags or contents. My XML file has lines like this:

<?xml version="1.0" encoding="ISO-8859-1" ?><!DOCTYPE PD>
<PD version="4.1">
    <Misc>
        <property value="Comments"> </property>
    </Misc>
    <EmptyTag>
    </EmptyTag>
</PD>

Which is read in Matlab as:
tree =
         Misc: [1x1 struct]
     EmptyTag: []
    ATTRIBUTE: [1x1 struct]

tree.Misc.property =
      CONTENT: []
    ATTRIBUTE: [1x1 struct]

So far, so good. However, on writing, the XML file is malformed:
<?xml version="1.0" encoding="UTF-8"?>
<PD version="4.1">
    <Misc>
        <property value="Comments"/>
    </Misc>
    <EmptyTag/>
</PD>

I do not understand the DOM structure enough to try to find a cure for this. Also, setting tree.EmptyTag=' ' (one or more spaces) results in the same output.

How can this be corrected?

EDIT
Ok, it is amazing how fast bright ideas come after posting a problem.

I noticed that setting:
set(objOutputFormat, 'PreserveSpace', 'on')
in xmlwrite_xerces.m ~ line 48 deals with the problem and outputs a genuine XML file.

Unfortunately, the layout is unreadable (for larger xml files) to the eye:
<PD version="4.1"><Misc><property value="Comments"></property></Misc><EmptyTag></EmptyTag></PD>
