HTML Escape Characters

I have some registration forms in my web site, I wan to prevent user from entering HTML tags in input text fields and textareas (actually HTML injection), In fact I want to display the entered info in a way that entered HTML tags don't affect on the appearance of the web site and the actual tags be displayed on the page. I know that the solution is replacing the critical characters in the entered text with their corresponding Escape codes, But is there any class or method which does this for me?
I know there are such functions in Perl and PHP.

You can use StringEscapeUtils from Apache commons...
String HTML = "<B>$ to \u00A3 Rate</B>";// Original values
System.out.println(HTML);
System.out.println();
// Conversion examples
System.out.println(StringEscapeUtils.escapeJava(Java));Produces...
<B>$ to £ Rate</B>

Displaying unicode or HTML escaped characters from HTTPService in Flex components.

Here is a solution on the Flex Cookbook I developed for
displaying data in Flex components when the data comes back from
HTTPService as unicode of HTML escaped data:
Displaying
unicode or HTML escaped characters from HTTPService in Flex
components.

Hi again Greg,
I have just been adapting your idea for encountering
occasional escaped characters within a body of "normal" text, eg
something like
hellô sun&scaron;ine
Now, the handy String.fromCharCode(charCode) call works a
dream if instead of the above I have
hellô sunšine
Do you know if there is an equivalent call that takes the
named entities rather than the numeric ones? Clearly I can just do
some text substitution to get the mapping, but this means rather
more by-hand work than I had hoped. However, this is definitely a
step in a useful direction for me.
Thanks,
Richard
PS hoping that the web page won't simply outguess me and
replace all the above! Basically, the first line uses named
entities and the second the equivalent numbers...

Converting HTML Escaping to Unicode Escaping characters in Java

Hi,
I am getting some HTML escaping for special characters like pound, space, dollar etc. from database in HTML escaping format as ' £ ® etc.which I want to convert their Unicode equivalent escaping as U00A3,U0026. Java only convert & to & (U0026) but rest of the characters are not getting converted. If there is any API or way to do this please reply.
Note : I cant change Database as there are already thousands of records & My front end only needs Java to do all these conversions I cant change that also.

I have posted a method that does what you want. It was a long time ago since I wrote it and you should probably use a StringBuilder instead of a StringBuffer if you are going to use it in Java 5 or later. You can find the method in this thread:

Web Logic 10.3 upgrade causes issues with escaped characters in JSP.

We recently upgraded our application servers from Weblogic 9.2 to Weblogic 10.3 and we are having an issue with escaped characters in a JSP code. Here is an example of what we are seeing:
var convertedBody1 = document.getElementById('body').value.replace(/\$FIRST_NAME\$/g, firstName);
This code works in Weblogic 9.2. In Weblogic 10.3 we have to make the following changes:
var convertedBody1 = document.getElementById('body').value.replace(/\$FIRST_NAME\$/g, firstName);
Thanks, Tom

Hi:
I have resolved the issue with the following in the jspx page.
Put an
<jsp:scriptlet>
response.setContentType(“text/html; charset=UTF-8”);
</jsp:scriptlet>
Inside the <f:view> on the jspx file.
Please refer the link http://www.oracle.com/global/il/support/tip/nlss11061.html for more details. It is helpful.

Official documents on escaping characters in SQL Server query statements

Hi,
Are there any official documents on how to escaping special characters in SQL Server query statements? I find a lot of online resources discussing about this, but there are no definitive conclusions on:
Which characters should be escaped? (Some only said single-quote needs to be escaped, double-quote does not need. While others said both need to be escaped)
How to escape characters? (Some said using two single-quote to escape a single-quote. Others said using a backslash, etc.)
So I just wonder if there is an official document from Microsoft regarding this?
Thanks
Alan

Depends on where you're using them
If its string values then single quotes(') should be escaped by putting one more single quote before it.
If its LIKE operator you can use ESCAPE keyword or use [] to escapre special characters
see
http://visakhm.blogspot.in/2013/01/wildcard-character-based-pattern-search.html
If inside SSIS expression you can escape characters like \ " etc by adding an extra \ before the characters
Please Mark This As Answer if it helps to solve the issue Visakh ---------------------------- http://visakhm.blogspot.com/ https://www.facebook.com/VmBlogs

Handling HTML-reserved characters in passed item values

I've got a pair of pages in an application where one gets an item value from an inline value of a report on the other page. Since the link I created is conditional, I used the concatenate html string method to create the link. However, some of the values that are getting passed contain "+" as part of the value. How can I get this value to pass via the concated HTML string?
Here's the SQL I'm using:
SELECT x.*
,decode(x.source,'S','<a href ="f?p=&APP_ID.:403:&SESSION.::&DEBUG.:RP:P403_PAGE_LOAD,P403_LOT_NO,P403_ATTRIBUTE:1,'||x.lot_no||',\'||to_char(x.attribute)||'\">S</a>','P') as icon
FROM x
where x.attribute sometimes contains the "+" character.
Any help would be appreciated!

Thank you both for replies ....
Since these urls are generated through code, what is the best way to go about it ?
Could you please explain a little about using of hash map in this case?
and excpet using escape characters, is there any other way to do it ?
Thanks again

Element type attributes doesn't accept HTML escape codes in 10.1.4

In 9.0.4 we often used HTML escape codes in attribute values for element types when we needed to use special characters, for instance using « becomes « and so on.
In 10.1.4 however, this doesn't seem to work any longer. For instance « becomes
&laquo; which of course looks like garbage when you use the element type on a page. Anyone found a workaround to this ?

The workaround I've been using is running
ttyctl -f
as early as possible in my zshrc.
stty will be non-functional while ttyctl is freezing the terminal settings but in my case, since I'd never even heard of that command prior to my searches in finding a fix, I can't say it really bothers me. At least I can run yaourt now without having my terminal messed up. If you do use stty often, here's a function that'll unfreeze the terminal settings first.

Html special characters

when using the Dreamweaver 'Set Text of Layer' behavior,
Dreamweaver correctly converts all html
special characters, such as accents like � and &,
and quotes and double quotes, so that it is safe
as a javascript string, and will display properly.
I am trying to figure out what PHP function can do the same
encoding, to simple text files (textEdit
on the Mac).
I have tried htmlentities(), but it does not work, accented
letters like � just desappear from the
string.
I have tried htmlspecialchars() and it does not work
either...
I have tried about 10 others functions found on Google but
nothing works.
Anybody knows what exact function Dreamweaver uses to do this
conversion?

How can I use escaped-characters in an option

I have the following code that is used to retrieve city-names including parent-child relations from a database and place them in an array:
<%@ page contentType="application/x-javascript" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql" %>
<sql:setDataSource dataSource="jdbc/KADOS" var="Raak" scope="session" />
<sql:query var="bewaringSQL" dataSource="${Raak}">
SELECT bewaringcode, vestigingsplaats FROM BEWARING order by vestigingsplaats
</sql:query>
bewaringen = new Array(
<c:forEach items="${bewaringSQL.rows}" var="plaats" varStatus="s" >
new Array( "<c:out value="${plaats.BEWARINGCODE}" />",
"<c:out value="${plaats.VESTIGINGSPLAATS}" />" )
<c:if test="${not s.last}">,</c:if>
</c:forEach>
i=0;
<c:forEach items="${bewaringSQL.rows}" var="plaats" varStatus="s" >
<sql:query var="bewaringGemSQL" dataSource="${Raak}" sql="SELECT KADGEMCODE, KGMNAAM FROM KADGEMEENTE where BEWARINGCODE=? order by KGMNAAM">
<sql:param value="${plaats.BEWARINGCODE}" />
</sql:query>
tmp = new Array(
<c:forEach items="${bewaringGemSQL.rows}" var="gem" varStatus="s" >
new Array( "<c:out value="${gem.KGMNAAM}" />",
"<c:out value="${gem.KADGEMCODE}" />" )
<c:if test="${not s.last}">,</c:if>
</c:forEach>
bewaringen[2] = tmp;
i = i+1;
</c:forEach>
function bewaringenList(selectCtrl, itemArray) {
for (i=0; i<itemArray.length; i++) {
selectCtrl.options[i] = new Option(itemArray[i][1]);
selectCtrl.options[i].value = itemArray[i][0];
function setList(selectCtrl, itemArray) {
for (i=selectCtrl.options.length; i>=0; i--) {
selectCtrl.options[i] = null;
for (i=0; i<itemArray.length; i++) {
optie = filter(itemArray[i][0]);
selectCtrl.options[i] = new Option(optie);
selectCtrl.options[i].value = itemArray[i][1];
function filter( invoer) {
retour = invoer;
retour = retour.replace("'", "\'");
return retour;
The function 'bewaringenList' populates a <SELECT> with parent-names and
"setList(document.VraagForm.gemSelect, bewaringen[this.selectedIndex][2]);" populates the depending <SELECT> with child-names.
Some names contain single quotes (like "'t Zandt") and are displayd in the select-box as "&#039t Zandt".
I expected that the quotes could be replaced by escape-characters by 'filter(invoer)' but this does not work.
Is there a generic way to show these characters?
Ben

I don't understand why but this filter solved the problem:
function filter( invoer) {
retour = invoer;
retour = retour.replace("'", "'");
return retour;

Issue with escaping characters and php

Greetings,
We are working on a web page using php and Oracle. We have troubles dealing with the diferent escaping characters when inserting/retrieving data (magic quotes is on but adding the backslash doesn't help :( ).
We would like to know the correct way of dealing with those characters ( ' " / /n ...).
Thank you in advance,
Sincerely,
Oriol Nonell

Do NOT use addslashes/stripslashes to escape your queries. I use this function to do the escaping:
function escapeSQL($string, $wildcard=false)
$result = str_replace("'","''",$string);
if ($wildcard == true) $result = str_replace("%","%%",$result);
return $result;
It basically replaces ' with ''.
If you set $wildcard to false, then '%' is considered to be an actual '%' (for 'like' expressions). If you set it to true, a % is escaped to %% too.

There are to bugs:
Bug 5403652 - ERROR 'TEMPLATE CANNOT CONTAIN ESCAPE CHARACTERS' WHEN VALIDATING A MAPPING
Bug 5561224 - MIGRATION OF MAPPING REQUIRES CHANGE IN CONFIG TO ALLOW VALIDATION
against OWB 10.2.0.1
but these bugs are fixed from 10.2.0.2
The bug is related to pre/post mapping operators...
If you are on 10.2.0.3 or your mapping does not have these operators then have no clue...

Bug in replace all. escape characters are not working.

Hi,
My requirement is that whenever i see ":" (Colon) in the string then i want to replace it with (\:). So i tried
String escapedTitle = "title:the world is not enough".replace(":", "\\:")
and to my surprise, when i printed escapedTitle i got
title\\:the world is not enough
instead of
title\:the world is not enough
(note the back slash in the string)
I want to ask why there is a different beehavious of escape characters? I am using JDK1.6.0_06

Sorry for the last post. Please try this:
public class test
public static void main(String a[])
     String escapedTitle = "title:the world is not enough".replaceAll(":+", "\\:"); //or [:]+
     String escapedTitle1 = "title:the world is not enough".replaceAll(":+", "*"); // or [:]+
     System.out.println("Another String is "+ escapedTitle);
     System.out.println("Another String is "+ escapedTitle1);
     System.out.println(System.getProperty("java.vendor"));
     System.out.println(System.getProperty("java.version"));
output is
Another String is title:the world is not enough
Another String is titlethe* world is not enough
Sun Microsystems Inc.
1.6.0_06
Please let me know why i am not getting : as escaped (\:) with replaceAll method.
i want string escapedTitle as Another String is title*\:*the world is not enough

Validation - template cannot contain escape characters

Hi all, im new to Warehouse builder, i find the documentation lacking, the tutorials lacking and i can't find any books on warehouse builder either. Am I stupid ? :-)
Anyway, i've set up 3 constants (varchar2) to pass as parameter values to a function im calling and when i try to validate the mapping im getting 'Template cannot contain escape characters'.
Then im getting validation completed successfully..however, when i try to deploy im getting this:

Template cannot contain escape characters

I created a database function which takes a varchar2 variable as input and passes back a number as output.
I am using pre mapping process to call this function and I created a constant with the value I want to pass to this function. When I try to validate my mapping I am getting this error
Template cannot contain escape characters.
Why am i gettign this error any ideas as to how to fix this. I know for sure the join of the constant to the input mapping process is causing this error but my constant variable just has
'xxxxx_xxxx' no other characters.
Thanks

Hi
Are you using the 10.2.0.1 production release, I think this is bug 5403652. It should be fixed in a patch after (10.2.0.2 onwards), you could also try set based only code generation and see if this bypasses the problem (there is a comment in the bug indicating it is a row based code gen bug).
Cheers

Reading in/writing out escape characters from/to file

I am trying to read in a large file which has many escape/special charaters (e.g. /, double quote (" ") etc.). I need to read them as they are and then write them out in a separate file as they were in the original file (e.g. if there was a double quote in the original file, I would have to keep the double quote in the output file)
Now my question is: how can we tell the BufferedReader and FileWriter not to treat those characters to be escape characters?
Thanks

Now my question is: how can we tell the
BufferedReader and FileWriter not to treat those
characters to be escape characters?AFAIK, you don't need to do anything special. BR and FW already do that the right way.
Did you try the standard approach?
