XML内容似乎不是XML

Question

Above is the error I have when I was trying to read 80 xml files in a for loop. The problem is with xmlParse . It worked well with others, but only 1 file. I am not really understand about built function. I just want to ask how to skip xmlParse error.

xmlParse(file)

Error: XML content does not seem to be XML: 'sample.part40.xml'

Answer 1

When iterating over a list of files, if you see this error, it normally means the content of that specific file is not xml . This happens often when the files have been scraped off the web (for example, one might be a generic 404 file instead with no xml content).

I normally use something like this:

 results <- lapply(listOfFiles, function(f)  
                {X <- try(xmlParse(f))
                 if (inherits(X, "try-error")) NA else X} )
