Mar 26, 2015Is there anything wrong with writing JSP tags in psuedo-HTML? I've been writing tags in XHTML, but it would seem that XHTML could not be compliant with both an XHTML standard and the HTML5 standard.

SAX Parser / Tags And Text Don't Line Up
Feb 9, 2015 how to use SAX Parsers. I've looked at a few tutorials and have the generals down. I have an xml file that the parser is trying to read. As you see below, at the start of each element, I add the tag to an arrayList of the tags. I create a stringBuilder to capture the text between tags, this won't work unless it occurs at the end of an element. If it occurs at the start, it never gets the chance to read the text.
This is where the problem occurs. For nested tags, like project, it reads the last nested tags' text and stores it in the text arrayList. Project may be the first indexed tag in the tags arrayList, but project's text is the fourth indexed element of the text arrayList. So when my test print the arrayLists by index, it gets thrown off. I want over tags to store a blank space in the text array, and at the same index of the tag its associated with. How would I do this?
I've tried overwriting the text arrayList, but couldn't get my logic thought out for how to determine if a tag was nested. I always ended up overwriting blank space to each element.

How To Write ID3 Tags Using MP3agic Library
Apr 22, 2014I am trying to write the id3 tags using mp3agic library. The problem is it does not update the id3 tags for the mp3 files which already contains id3 tags but it only updates the file that have id3 tags which are empty.
When i look at the newly created files, they contains the older tags. Then i wrote a script to access id3 tags through mp3agic
id3v1Tag.getArtist()
then it was showing updated tags.
Why it is showing updated tags even if they are not really updated in folder where i visits ?
Program To Scrape All Title Tags From Large Sites
Apr 9, 2015I am familiar with php, but I don't know Java. We need a program, that will be able to scrape large amount of title tags from large sites, fast. I've been trying Seo Spider by Screaming Frog, and Xenu's Link Sleuth, but these programs are not good enough. They hang up, they save all the data in RAM, I think, and after a relatively short period of scraping, they stop working, become unresponsive, and so on.
Somebody recommended me getting a custom made program in Java, which would be able to scrape title tags only, from large sites (I am talking 25 - 50 million pages or more). I was told that it would not have a graphic interface, or anything like that. Nothing like this is needed too, we just need to have title tags.
JSF :: What Tags Of Xhtml View Will Be Build As UIComponents In Server Side
Jun 8, 2014In order to create an xhtml view:
1. All jsf tags like datatable, form, etc.. will generate UIComponents in server side, right?
2. All non JSF tags will not generate UIComponents in server side, right?
3. If you want something in a view that will be the same across users and requests, I mean, It will not change like a label tag, it doesn't make any sense to create it with a JSF tag in order to save memory in server side, right?

View Replies View RelatedDOM Parsing Method
Feb 26, 2015I've been staring at my code for the past few days and I just can't get it to work out. I'm trying to parse a DOM object with the following XML loaded:
<?xml version='1.0' encoding='UTF-8' ?>

I'm trying to get all of the attributes that I care about out of the <record> tags (date, event, etc ...) and stick the data in a wrapper class (DocumentData). If you run this, you'll see that it is close to working, but I'm having trouble getting the attributes in the <subject> and <return> tags (I need to get the errval and uid attributes).
Parsing A Value From A String
Jul 1, 2014I'm simulating temp/humidity values and want to separate the string value reported and parse each part (left and right) for their respective values. However, I'm having trouble figuring out how to parse the right hand side of this string value, I can get the left using split (shown below), but I think split removes the right hand side of the string value.
the value reads "Temp=22.9*C Humidity=50.9%"
Java Code: private Double parseTemperatureFromString(String consoleOutput) {
String[] tempHumidParts=consoleOutput.split(" ");
String[] tempPart=tempHumidParts[0].split("=");
String theTemp=tempPart[1];
theTemp=theTemp.replace("*C","");
return Double.parseDouble(theTemp);

ArrayList - CSV File Parsing
Nov 18, 2014I have to read this CSV file into an arraylist. Arraylist i call weight. The data in the csv file has 200 double values which is the weight of all the 200 bananas. Since the csv file is a string i guess I cannot create an double arraylist from scratch, but i have to parse the csv file afterwards, right? Well this does not work and ill show you the code in a bit, just need to state all my issues.
My second issue is how to be able to print out the the weight items (in this case bananas) next to the weight of the bananas taken from the array? This has to be done by constructor i assume? I just dont know how constructors work with arraylists.
Id like it to look something like this in the output window.
Banana 34,55
Banana 43,55
Banana 23,74
and so on (200 times)
so these are my issues, how to parse and how to print the arraylist weights and the item banana in the output window with constructor. Here is the code.
package Main;
import java.io.BufferedReader;
import java.io.FileReader;
import java.util.ArrayList;
import java.io.IOException;
import java.io.Serializable;
import javax.swing.JOptionPane;

View Replies View RelatedParsing CSV File - Column And Row Data?
Dec 19, 2014I am trying to merge two files together using the Apache Commons CSV library. I figured it was easier to use this than to write my own implementation.
The first problem is that the output contains the underlying class logic and as a results my output contains a bunch of un-needed data. How do I get rid of this? I just want the column and row data, nothing else.
Example
I want this:
customerNo, firstName, lastName, birthDate, mailingAddress, married, numberOfKids, favouriteQuote, email, loyaltyPoints
1, John, Dunbar, 13/06/1945, 1600 Amphitheatre Parkway Mountain View, CA 94043
But I get this:
CSVRecord [comment=null, mapping=null, recordNumber=1, values=[customerNo, firstName, lastName, birthDate, mailingAddress, married, numberOfKids, favouriteQuote, email, loyaltyPoints]]
CSVRecord [comment=null, mapping=null, recordNumber=2, values=[1, John, Dunbar, 13/06/1945, 1600 Amphitheatre Parkway
Mountain View, CA 94043
The second problem is that I just want the row Headers from the first file, but the row headers from my second file are still being included in my output. I used withSkipHeaderRecord(true), but it didn't have the desired results.
Code is below.
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import java.io.PrintWriter;
import java.io.Reader;
import java.util.ArrayList;

Parsing Image Location - In Constructor Or Where
Jun 4, 2014I'm working on a small game, and I have a quick question about parsing a file. Basically, I have a utility method, which loads an XML file containing the details of all the items for the level, and then pulls the info and passes it to the Item constructor.
A snippet of the XML file is:
<item key = "Weapon1" name = "Sword" description = "A basic sword... etc" hint = "picked up SWORD" givesPlayer = "basicSword:1" bitmap = "5,5" />
And a snippet of the class is:
public class Item extends Entity {
String name;
private String description;
private String hint;
private Map<String, Integer> givesPlayer = new HashMap<>();
private boolean pickedUp;
[Code] ....
The XML file contains this field:
bitmap = "5,5"
which basically specifies a column and row where it should grab an image from, located elsewhere.
My question is this: Should I parse this "5,5" in my utility method and pass the image(s) to the constructor(// B Consturctor), or is it ok to pass the location as a String and parse it in the Constructor( // A Constructor) ?
