Stripping HTML Tags from a String

What's the best way to remove html tags from a string (i.e. user input)?

Can you give an example? You can do substring, if your passing spaces between pages you can do a trim to the variable. Also look at the indexOf(). Look at methods relating to java.lang.String.

How to remove HTML tags from a String ?

Hello,
How can I remove all HTML Tags from a String ?
Would you please to give me a simple example ?
Best regards,
Eric

Here's some code I cooked up. I have created an object that processes code so that it can be incorporated directly into a project. There is some redundancy so that the it can be used in more than one way. Depending on your situation you might have to make the condition statement a little more sophisticated to catch stray ">" tags.
I have also included a Tester application.
//This removes Html tags from a String either by submitting the String during construction and then
// calling getProcessedString() or
// by simply calling " stringwithoutTags=removeHtmlTags(stringWithTagsSubmission); "
//Note: This code assumes that all"<" tags are accompanied by a ">" tag in the proper order.
public class HtmlTagRemover
 private String stringSubmission,processedString,stringBeingProcessed;
 private int indexOfTagStart,indexOfTagEnd;
 public HtmlTagRemover()
 public HtmlTagRemover(String s)
 removeHtmlTags(s);
 public String removeHtmlTags(String s)
 stringSubmission=s;
 stringBeingProcessed=stringSubmission;
 removeNextTag();
 return processedString;
 private void removeNextTag()
 checkForNextTag();
 while((!(indexOfTagStart==-1||indexOfTagEnd==-1))&<indexOfTagEnd)
 removeTag();
 checkForNextTag();
 processedString=stringBeingProcessed;
 private void checkForNextTag()
 indexOfTagStart=stringBeingProcessed.indexOf("<");
 indexOfTagEnd=stringBeingProcessed.indexOf(">");
 private void removeTag()
 StringBuffer sb=new StringBuffer("");
 sb.append(stringBeingProcessed);
 sb.delete(indexOfTagStart,indexOfTagEnd+1);
 stringBeingProcessed=sb.toString();
 public String getProcessedString()
 return processedString;
 public String getLastStringSubmission()
 return stringSubmission;
public class HtmlRemovalTester
 static void main(String[] args)
 String output;
 HtmlTagRemover h=new HtmlTagRemover();
 output="The processed String: "+h.removeHtmlTags("<Html tag>This is a test<another Html tag> string<yet another Html tag>.");
 output=output+"\n"+" The original string:"+h.getLastStringSubmission();
 System.out.print(output);

Remove HTML tags from a string

I have a string that contains a couple of HTML or XHTML tag, for example
lv_my_string = 'Hello World!'.
For a special use case, I want to remove all HTML from that string and process only the plain text
lv_my_new_string = 'Hello World!'.
Is there any method, function module, XSLT or anything else for that already?

Hi Daniel,
I tried using the FM (SWA_STRING_REMOVE_SUBSTRING) but I guess it is expecting a particular pattern which is not so apparent in your case. Iu2019ve written a small piece of code which you can try using in a FM or a PERFORM and that should do the trick. Please let me know if you have any questions.

Oracle function to strip HTML tags in data

Hi, may I know if there is any oracle function that can strip HTML tags from the data? I am currently using Oracle 9i. Therefore is unable to use the RegExp_Replace functionality provided by Oracle 10g.
Any help will be appreciated.
Thanks a lot!

I found this function:
function str_html ( line in varchar2 ) return
varchar2 is
x varchar2(32767) := null;Let's hope whoever uses this doesn't want to deal with large XML's.
This question would have been better asked over in the XDB forum. All depends whether there is a schema available to describe the XML, what version of the database etc. With a schema, the schema could be registered into the Oracle 10g database and that used to create relational tables automatically, from where you can load in the XML files. Loads of information available on the XDB forum, most likely in the FAQ's on there.

How to exlcude HTML Tags from Excel Reports

Hi Guys
Within Project Online - OData extract to Excel
Has anyone found a way to eliminate the HTML tags from Multi Line Text fields within Project Server? I can easily extract the text and generate nice Excel Reports, but the html tag is very annoying in the Excel Reports and it doesn't read easily.
Any help would be appreciated.
Marc Soester [MVP] http://marcsoester.blogspot.com

Marc,
What you could do (given that you find the required time and energy to write the lines),
would be to replace all (!) html characters like here (http://stackoverflow.com/questions/14705605/remove-html-tags-from-cell-strings-excel-formula -
this is one of the Excel UDF/VB-based solutions, but will not refresh in Excel Services - however there is a good list of what to replace) with PowerQuery.
That would refresh over a PowerBI subscription in the least..

Way to remove HTML tags from a page-scoped attribute using JSTL?

Hi,
I'm using JSTL 1.2 with Tomcat 6.0.26. Does anyone know of a way to remove HTML tags from a page attribute, "${myExpr}". I would prefer a solution that uses JSTL only, but ultimately whatever gets the job done is fine with me.
Thanks, - Dave

I'm sorry, I don't understand your requirement. What do you mean by "remove HTML tags from a page attribute"?
If you are dealing with a value of an attribute, it is most likely a String, and should be treated as such. The best approach would probably be java coding.

Integrate html tags in a string and display it in a multiline text area

Hi ABAPers!!
First of all let me tell you that I'm working in ACCENTURE Casablanca(Morocco) and this is my first Job in my career.
I'm working on an ALV OO, the program consists on creating an ALV using OO, In my selection screen there's a parameter of type ddobjname I provide the name of table and it returns the table's fields in another dynpro (screen0100), To do this I used the FM: 'DDIF_FIELDINFO_GET' then I append the internal table returned in another one to add the field CB (CheckBox), and I add a button in the toolbar, the function of this button is to generate a MySQL script To create the table provided by the user in my parameter (Screen 1000), but the fields of this table(MySQL) in the generated script are only the selected ones by cheking the checkbox in the ALV.
I store my script in a string.
My problem is that I want to show my script in a text area, but I don't know how to create a multiline text area!!
And I want to use HTML tags in my string.
I don't want to my string like this :
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI ( CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY , FLTIME INT ( 10 ) , DEPTIME DATETIME ( 6 ) , DISTANCE DOUBLE ( 9 ) , FLTYPE VARCHAR ( 1 ));
But I want it to be shown like this:
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI (
CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY ,
FLTIME INT ( 10 ) ,
DEPTIME DATETIME ( 6 ) ,
DISTANCE DOUBLE ( 9 ) ,
FLTYPE VARCHAR ( 1 ));
Thanks in advance

Hi again!!
You know what!! let's forget the HTML and focuse on what I want to show.
As I told you, I've a string which contains my script.
I don't want that it will be shown as a simple line like this :
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI ( CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY , FLTIME INT ( 10 ) , DEPTIME DATETIME ( 6 ) , DISTANCE DOUBLE ( 9 ) , FLTYPE VARCHAR ( 1 ));
But I want it to be shown as follows:
CREATE [TEMPORARY] TABLE [IF NOT EXISTS] SPFLI (
CONNID CHAR ( 4 ) NOT NULL PRIMARY KEY ,
FLTIME INT ( 10 ) ,
DEPTIME DATETIME ( 6 ) ,
DISTANCE DOUBLE ( 9 ) ,
FLTYPE VARCHAR ( 1 ));
and finally I want to show it in a multiline text area.
Plz what shud I do?!!! If possible I need a piece of code.
PS : I create a HTML Viewer using this code :
DATA : go_conteneur          TYPE REF TO cl_gui_docking_container,
             go_controle_html    TYPE REF TO cl_gui_html_viewer.
CREATE OBJECT go_conteneur
    EXPORTING
      repid     = sy-repid
      dynnr     = '0100'
      side      = go_conteneur->dock_at_bottom
      extension = 1000
      name      = 'CONTENEUR'
    EXCEPTIONS
      OTHERS    = 1.
CREATE OBJECT go_controle_html
    EXPORTING
      parent = go_conteneur
    EXCEPTIONS
      OTHERS = 1.
But when it's shown my ALV disappears!!!

HTML tag in Coldfusion string not appearing

Hey guys I'm wondering what I'm doing wrong when trying to
store an html tag in a string. Basically I'm dynamically creating a
list for use in a javascript menu, so when building the menu, I do
this:
menu = "< ul id = """ & mainID & """
> ";
to generate a list (of course thats only part of the list
code). This line produces < ul id = "mainID" >
What I need is for the spaces to be removed, so it would
produce <ul id="mainID">
But in my Coldfusion function, if I write:
menu = "<ul id=""" & mainID & """> ";
nothing shows up! A space between < and ul works fine, but
once I delete them, nothing! Any help would be really appreciated,
thanks.

actually found the answer elsewhere, I declared a variable
open = < now instead of using the <, i just write open,
which generates the list fine.
but a followup, the list is being generated now, but on the
page instead of the javascript/css menu catching it and formatting
it, it just displays the whole list, tags and all. I tried
htmlEditFormat( ), that only changed all the symbols to their I
guess ASCI couterparts. Any ideas why its showing the list as text
rather than creating a menu??
also I tried it without the menu, which should have shown a
bulleted list, but that didn't work either...

How do I set BI Publisher to read html tags from the database?

How do I set BI Publisher (Release 10.1.3.4) to read html tags from the database? For example if the text is quoted with a bold tag I want my output to display the text in bold. Is there a setting or something I can set?

I took a look at Tim Dexter's blog as suggested and the sample worked, but for the elements in the xml file not for the value coming from the database, however this is good to know as well!
I have data in the data base column which looks like this:
'MS Applied <B(bold tag)> Mathematics</B(bold tag)>University of Southern California'
I want the data to be rendered like this:
'MS Applied Mathematics University of Southern California'.
In Report Builder on the property sheet I would set Contains HTML Tags property to Yes and the report would render correctly.
In BI Publisher 10.1.3.4 I can not seem set it to read this I have change the configure properties of the report to Character set to HTML and Make HTML output accessible to True. I just can't figure out what I'm missing.
Thank you for any assistance you can offer.

How to aviod html tags from Report column heading while export to csv

Hi All,
How to aviod html tags from Report column heading while export to excel.
We used like Employee Department in column heading, but the problem is the tag also exporting into csv file.
If any column data 3/2009 formatt the it will exporting as marh 2009.
Please help on this.
Thanks,
Nr
Edited by: pnr on Jul 5, 2011 5:00 AM

Hi Nr
Here is how I approached this problem.
Go to report attributes tab
under column attributes check PLSQL radio button.
Create a function to return the heading of your report as shown below in your database.
create function get_heading return clob as
v_request VARCHAR2(20) := V('REQUEST');
v_col_heading CLOB;
begin
IF INSTR(v_request,'FLOW_EXCEL_OUTPUT',1) > 0 THEN
v_col_heading := 'Employee Number:Employee Name';
ELSE
v_col_heading := 'Employee breaktag Number:Employee break tag Name';
END IF;
return v_col_heading;
end;
Type the function below under ( Function returning colon delimited headings:) as follows.
return get_heading;
Similarly for data base it on PLSQL function body returning SQL and follow the same approach as headings.
Hope this helps.
Thanks

Remove HTML tags from a text area

Hi, here is my problem:
I have a form with a text area item; this item is “Display as Editor HTML standard”. So it is possible to enter formatted text with tags HTML. Then I save the text in a table. In the column the text maintain the HTML tags. Afterwards I can put the text in a report, and I can see the formatted text with the tags HTML interpreted.
But I need also to use that text for other aims, (i.e. sending it in a mail) with the html tags removed.
Is there any way to remove HTML tags from a text item?

Stripping all HTML tags from a CLOB

Hi all,
Running Oracle 9.2.0.8 on AIX...
We have a table which stores HTML document fragments in a clob. I have a requirement to convert these to plain/text (strip all HTML tags) for sending in a plain/text email body.
I have read the following solution from Tom Kyte's site:
http://asktom.oracle.com/pls/asktom/f?p=100:11:0::::P11_QUESTION_ID:25695084847068
Basically creating an Oracle text index on the CLOB column and calling ctx_doc.filter with "plaintext" parameter set to true.
I noticed in Tom's example, he uses the default filter, which based on the docs, is NULL_FILTER, which applies no filtering. I have tried his example in my dev box, creating the text index on the CLOB column with no parameters.
The call to ctx_doc.filter did not filter the html at all. I re-created the index and specified the INSO_FILTER and the filtering was done. I was under the impression that INSO_FILTER was for filtering binary content to plaintext...
create table filter ( query_id number, document clob );
create table demo
( id int primary key,
 theclob clob
create index demo_idx on demo(theClob) indextype is ctxsys.context;
SET DEFINE OFF;
Insert into DEMO
 (ID, THECLOB)
Values
 (1, '<html><body>This is a test of ctx_doc.filter and plaintext filtering.</body></html>');
COMMIT;
exec ctx_doc.filter('demo_idx',1, 'filter',1, true);The above code does not convert the html to plaintext...
Now re-create with the index with INSO_FILTER
drop index demo_idx;
create index demo_idx on demo(theClob) indextype is ctxsys.context parameters ('filter ctxsys.inso_filter');
exec ctx_doc.filter('demo_idx',1, 'filter',1, true);Above scenario returns string "This is a test of ctx_doc.filter and plaintext filtering."
The ORacle documentation doesn't specify any special filter parameter that needs to be set... just wondering if I'm missing soemthing here... or better yet, if there is a better solution to my problem. ;-)
Thanks
Stephane

The difference between what you did and what Tom Kyte did is that you created your index on a clob column and Tom created his index on a blob column. What I don't know is why that makes a difference. I have demonstrated below with one blob column and one clob column, one index on the blob and one index on the clob, using the same code on both, with different results.

Remove HTML tags from String

it sounded prettty easy..
I know the first part of my String is <html><center> and the last part is </center></html>
but for saving it into the database I want to remove the HTML parts..
I know how much characters the html stuff is.. I know what the html is.. how do I remove it from my string?

If your String always starts with <html><center> and always ends with </center></html> you can use:
 int startLength = "<html><center>".length();
 int endLength = "</center></html>".length();
 String withoutHtml = myString.substring(startLength, myString.length() - endLength);
