The easiest thing (other than just your own text editor), is xml2struct and struct2xml from Wouter Falkena from the File Exchange:
Your example is missing a square bracket on line 7 but that should not interfere with XML parsing. For more complicated XML problems use the MATLAB XML Parser MAXP. See the article "Import an XML File into a Document Object Model" in the help documentation.
>> S = xml2struct('Ptr.val.txt')
S =
struct with fields:
PtrVal: [1×1 struct]
>> S
S =
struct with fields:
PtrVal: [1×1 struct]
>> S.PtrVal
ans =
struct with fields:
Ptr: [1×1 struct]
Attributes: [1×1 struct]
>> S.PtrVal.Ptr
ans =
struct with fields:
Ptr: {1×19 cell}
>> S.PtrVal.Ptr{1}
Brace indexing is not supported for variables of this type.
>> S.PtrVal.Ptr.Ptr{1}
ans =
struct with fields:
Text: [1×0 char]
Attributes: [1×1 struct]
>> S.PtrVal.Ptr.Ptr{1}.Attributes
ans =
struct with fields:
Name: 'DG.RO[0]'
Value: 'Default'
