问题 I'm using CKEditor 4, which seems to have a default setting of using <p></p> to indicate a blank line. Up to now, I've always seen blank lines in HTML represented by <p> </p> - ie. not an empty tag. So CKEditor's default output representing a blank line is, eg: <p>paragraph before blank line</p> <p></p> <p>paragraph after blank line</p> The problem is, for a change, IE7,8,9 seems to render this "correctly" as a blank line, whereas Firefox and Chrome do not - they seem to ignore empty <p> and

问题 I am reading in a CSV file as a DataFrame while defining each column's data type. This code gives an error if the CSV file has a blank row in it. How do I read the CSV without blank rows? dtype = {'material_id': object, 'location_id' : object, 'time_period_id' : int, 'demand' : int, 'sales_branch' : object, 'demand_type' : object } df = pd.read_csv('./demand.csv', dtype = dtype) I thought of one workaround of doing something like this but not sure if this is the efficient way: df=pd.read_csv(

问题 How do I ignore an empty first line in "input.txt"? I don't necessarily know that there is an empty line (in this particular case there is, but I want to make my code generic), so I need to be able to read the line if there is information, or skip it if it is blank. This is just for the first line. while (getline(mcFile, line)) { istringstream liness2(line); ... } That's how I'm reading the lines. If I knew for certain that any input file I ran this on had an empty first line, I would just do

问题 I am doing a text analysis with R and needed to convert the first letters of the sentences into lowercase while keeping the other capitalized words the way they are. So I used the command x <- gsub("(\\..*?[A-Z])", '\\L\\1', x, perl=TRUE) which worked, but partially. The problem is that for the text analysis I had to convert the pdf files into txt format and now the txt files contain a lot of empty lines (page breaks, returns possibly), and therefore the command I used does not convert the

问题 Is it possible to remove all blank ROWS from a CSV file? I'm trying to count all rows from a CSV file but would like to exclude lines that doesn't contain a value on a specific column or the whole row.
