Best way to extract from HTMl

There are about 4 or so <br/> tags in a certain html code block that I have as a string. What is the most efficient way (I have a way right now to do it, but it seems to be slow) to get the text between the second and third of these tags

ex.

a<br/>b<br/>c<br/>d<br/>e

How do I get "c" in the most efficient way

    Regex would be one way of doing it but its expensive but ideal for these type of problems.

    Alternatively you could do a string.split on the <br/> tags, so any values between the br tags are in the string array:

    string[] theItems = theTags.Split("<br/>");

    theItems would (should) contains:

    a

    b

    c

    d

    e

    but of course will consume more memory depending on how many items there are

    There are other ways also but these are the most common used

    try this:

    string theString = "a <br/> b <br/> c <br/>";

    string theSplitChars = "<br/>";

    string theArray[] = theString.Split(theSplitChars.ToCharArray(), StringSplitOptions.RemoveEmptyEntries);

     

    does this work for you

    string[] theItems = theTags.Split("<br/>");

    I tried that before posting. Didn't work. You can't input a string as an argument, only a character array. So you would probably say, add ToCharArray() but I tried that and it doesnt work, it seems to have only used the array[0] for the splitting...

    Regex is what I considered doing, but I've almost never done regex before, and I need some help with how to implement the regex...

  • Floaf

    Trying it, but you forgot to make the string an array


  • libyan

    Nope it doesnt work, it seems it only takes the first character of the string and uses that as the splitter

    wow - works fine for me over here....I'll see what else I can dig up
