Hi everyone .
I,m trying to read a webpage ( which is dictionary webpage ) with matlab and convert html data to text with extractHTMLText for get some informations but MATLAB gives this error :
" Error in XML : Empty XML namespace is not allowed . "
Since I am not a professional programmer , I am not familiar with the namespace and its errors .
code :
url='https://www.vocabulary.com/dictionary/river';
options = weboptions('Timeout', 10);
code = webread(url,options);
textData = extractHTMLText(code);
complete error ( test is my script name ) :
Error using htmlTree (line 67)
Error in XML: xmlns:fb: Empty XML namespace is not allowed
Error in extractHTMLText (line 40)
tree = htmlTree(code);
Error in test (line 12)
textData = extractHTMLText(code)
As you can see , MATLAB has a problem only in the text analysis section of the read web page ( empty namspace error ) . I also checked the " code " variable , which has correctly saved the information of the web page .
Can anyone help me to fix this error ? Thanks .
