While it’s great to have online connections via LinkedIn, it’s also worth downloading more detailed contact information. Why You Should Export Your LinkedIn Contacts In summary, if you wanted to see a simple way to extract an HTML regular expression pattern from a String in Java, I hope this is helpful.You probably spend a lot of time cultivating valuable connections by prospecting on LinkedIn, and it’s likely that at some point, you’ll want to download those contacts’ information to further nurture those connections.īut, how do you do that? Where do you get started when exporting LinkedIn contacts - and what comes next? Read on for step-by-step directions with helpful, up-to-date screenshots. This code repeatedly calls the find method and prints the contents of the matching group until find doesn't locate any more matching patterns in the given String. In a more robust example, where you want to find and extract the contents of every code tag, your code would look more like this, using a while loop with the find method: It’s important to note that this example is hard-coded to look for only one occurrence of this group.
I then access this group using this line of code: In this example, the regex "(\\S+)" lets me extract everything between the opening and closing code tags as a group.
" īy using a group to extract the contents between the HTML opening and closing code tags, the output from this program is: String stringToSearch = "Yada yada yada StringBuffer yada yada. * extract a tag from a line of HTML using the Pattern * A complete Java program that demonstrates how to In the following source code I demonstrate how to extract the contents from a code tag from a longer HTML string:
Then use the find method of the Matcher class to see if there is a match, and if so, use the group method to extract the actual group of characters from the String that matches your regular expression. Solution: Use the Java Pattern and Matcher classes, and supply a regular expression (regex) to the Pattern class that defines the tag you want to extract.
Problem: In a Java program, you want a way to extract a simple HTML tag from a String, and you don't want to use a more complicated approach.
