xml-parser with perl
Hello
I want to write an xml- parser with perl an i use the libary XML::LibXML. I have a problem with the command getElementsByTagName. If there is an empty tag, the getElementsByTagName method returns a NodeList of length zero. how can i check if this is a nodelist of lenght zero?? i wanted to use a if loop if($var eq "") but then i get the error: Operation "eq": no method found, left argument in overloaded package XML::LibXML::NodeList, right argument has no overloaded magic at ./conv line 284. does anyone knows a solution to my problem? thx |
