Hello, from a software I have the following output in xml (see below): It is a series of matrices, for each age one. I have 3 categories (might vary in the application), hence, 3x3 matrices where each element gives the probability of transition from i to j. I would like read this data into R (preferably in a list, where each list element is one of the age specific matrices) and - after altering the values in R - write it back into the file. I know that there is an xml package in R with which I have already struggled, but I have to admit my understanding is too limited. Maybe somebody had a similar problem or know the code of the top of his or her head.
Any help appreciated. Thanks and best, Stefan <?xml version="1.0" encoding="UTF-8" standalone="no"?><transitionmatrix> <transition><age>0</age><sex>0</sex><from>1</from><to>1</to><percent>99.99999</percent></transition><transition><age>0</age><sex>0</sex><from>1</from><to>2</to><percent>0.0</percent></transition><transition><age>0</age><sex>0</sex><from>1</from><to>3</to><percent>0.0</percent></transition><transition><age>0</age><sex>0</sex><from>2</from><to>1</to><percent>0.0</percent></transition><transition><age>0</age><sex>0</sex><from>2</from><to>2</to><percent>99.999985</percent></transition><transition><age>0</age><sex>0</sex><from>2</from><to>3</to><percent>0.0</percent></transition><transition><age>0</age><sex>0</sex><from>3</from><to>1</to><percent>0.0</percent></transition><transition><age>0</age><sex>0</sex><from>3</from><to>2</to><percent>0.0</percent></transition><transition><age>0</age><sex>0</sex><from>3</from><to>3</to><percent>99.999985</percent></transition><transition><age>0</age><sex>1</sex><from>1</from><to>1</to><percent>100.0</percent></transition><transition><age>0</!
