Parsing elements that has special characters

I have to parse xml from a clob that has elements that contain characters cut and pasted from word perfect documents. The resulting text has the literal characters  and 
 inside the element start and end tags. I've looked at using an entity, but I'm not sure how the entity would look syntactically in the DTD. I want simply to eliminate those literals as they are causing an invalid character text error when I parse the xml in my stored procedure. I'm looking for any ideas or direction, thanks.

At the moment no, there isn't - you can try leaving feedback here http://www.apple.com/feedback/ipad.html

What does IE browser do when the slug value in the request header has special characters?

Hi ,
I would like to know how does IE browser handle slug if the value field has certain special characters.
For example if the slug header has special characters while posting the http request (say "äøéëåæ")
Then I see using http watch under the "Stream"tab , the slug value is getting converted to a different value(now the value for the above mentioned slug is " Ã¤Ã¸Ã©Ã«Ã¥Ã")
Could someone please explain how does this happen in IE browser?
Thanks alot,
Neelaja

It will disable the proxy server option in Internet Options (untick the box), but will still store your proxy details.

Processing XML files that contain Special Characters

Hello:
Before I explain my problem I think I should briefly explain what I am trying to do. I have a JSP page that invokes a Java method (the code is attached). This java method takes in an XML file and an XSLT file. It parses the XSLT and also the XML file. If the parsing went through fine, it then processes the XML file and applies the XSLT to the XML file and returns a XMLDocumentFragment Object back to JSP and the JSP renders it.
This mechanism works well. However off late I have encountered a few XML files containing characters such as &Ecirc (Capital E with circumflex accent). Whenever my Java method tries to parse/process this .xml file it gives me the following error.
ORG.oclc.da.utilities.ifs.ReportException: An Error Occured While Parsing the Report: Missing entity 'Ecirc'. at ORG.oclc.da.archive.userinterface.ReportHelper.retrieveReport(Unknown Source) at /ViewReport.jsp._jspService(/ViewReport.jsp.java:87) (JSP page line 65) at com.orionserver[Oracle9iAS (1.0.2.2) Containers for J2EE].http.OrionHttpJspPage.service(OrionHttpJspPage.java:54) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].server.http.HttpApplication.serviceJSP(HttpApplication.java:5458) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].server.http.JSPServlet.service(JSPServlet.java:31) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].server.http.ServletRequestDispatcher.invoke(ServletRequestDispatcher.java:501) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].server.http.ServletRequestDispatcher.forwardInternal(ServletRequestDispatcher.java:170) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].server.http.HttpRequestHandler.processRequest(HttpRequestHandler.java:576) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].server.http.HttpRequestHandler.run(HttpRequestHandler.java:189) at com.evermind[Oracle9iAS (1.0.2.2) Containers for J2EE].util.ThreadPoolThread.run(ThreadPoolThread.java:62)
It seems like the Oracle Parser/XSLT Processor (oracle.xml.parser.v2.DOMParser) I am using is not able to handle special characters such &Ecirc. I was wondering if there is anyway around this problem.
Attached is the Java Method that handles both the parsing and processing of the XML file.

If you have any suggestions please let me know. If you need more information I will be to furnish it.

Hello,
I just had the same problem, you need to include the approprate entity sets so that the xsl parser will recognize them (and you won't
get the "missing entity" error:
if you already haven't you need to add a DOCTYPE processing instruction for your dtd, to the top of your xml files to be parsed, for ex.:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "file:///mydir/mydtd.dtd">
then in "mydtd.dtd", add references to these 3 entity sets (if you have a dtd - if not then create one just with these entries):
<!ENTITY % HTMLlat1 PUBLIC
"-//W3C//ENTITIES Latin 1 for XHTML//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml-lat1.ent">
%HTMLlat1;
<!ENTITY % HTMLspecial PUBLIC
"-//W3C//ENTITIES Special for XHTML//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml-special.ent">
%HTMLspecial;
<!ENTITY % HTMLsymbol PUBLIC
"-//W3C//ENTITIES Symbols for XHTML//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml-symbol.ent">
%HTMLsymbol;
Or, grab the ".ent" files from the www.w3.org site and put them on your server in the dtd dir, and change the "http:... reference, to
"file:...", it will be faster to parse (that's what I did). FYI, "Ecirc" is in xhtml-lat1.ent.
Also, after I did this,I developed another problem where my xsl parser and xmlmarkup tag-converting function converts certain
html entities to their octal counterparts, and I don't want this and don't know how to stop it (I have a posting out for this also).
Additionally, thanks for posting your parseReport method, it just so happens that I was looking for a way to do something like that,
it should be helpful to me.

How to validate string that contains special characters.

Hi,
I am new to Data Services.I took excel sheet as a data source .Now i have do some validation functions like vendorgroup should not contain special characters ,name cleansing operations etc.. So,please anyone help me redarding this.
Thanks in advance

Anonymous,
No this is not a bug. Working with multi-select lists or any item which stores colon delimited values can be tricky to work with in APEX. There are a few work arounds for this. One is to replace the colons with something else like you described and then replace the colons on the landing page. Another solution is to send the primary key for that record and have an automatic row fetch or a computation pull the colon delimited value.
Cheers,

Help on querying data that contains special characters (#, &, @).

Hi there,
I am using forms 6i to query on a table whose primary key starts with a # (pound or hash sign). If I do the query trough sqlplus it comes back fine, but if I do trough forms 6i it gives me the following error messages: FRM-40831: Value too long for the field and then ORA-00920: Invalid relation operator.
Well I have followed the instructions on the note 1007499.6 published by metalink. They explaind that when in insert the # into a field forms is thinking that you are actually going to insert a relation operator like WHERE, BETWEEN and etc. So query that is run is somewhere like this:
select rowid
from emp
where (dname research)
In that case dname would be the field that start with the #.
They recommend as a workaround to write a pre-query trigger on the detail block to substr the # and add it the # againg with substr of the rest of characters, on note 1064159.6 by metalink.
I have written one with no success, the trigger seems to never be fired the errors fire first.
Can anyone help with that one ???
Thanks
gleisson silva

Try below in the pre-query, would also need a none DB block and variable :blocka.keyv:
IF substr(:dname,1,1) IN ('#','&','@')
THEN
:blocka.keyv:= substr(:dname,1,1)||:dname;
:dname:=NULL;
Set_block_property('tablename',DEFAULT_WHERE,'dname=:blocka.keyv');
ELSE
Set_block_property('tablename',DEFAULT_WHERE,'');
END IF;

Problem retrieving data that contains special characters in Collections

Hi fellow Apexers,
If I load strings that contain characters such as ":" or "," into a collection and then read the data back off the collection into page items via URL e.g.
f?p=&APP_ID.:4:&SESSION.::&DEBUG.::P4_INJURED_FIRST_NAME,P4_INJURED_OTHER_NAME,P4_INJURED_SURNAME,P4_INJURED_SHOP_NO,P4_INJURED_BUILDING,: #SEQ_ID#,#C001#,#C002#,#C003#,#C004#,#C005#
the data after the ":" or "," gets screwed up and ends up in the wrong fields. How do I escape these characters?
I have tried using a replace statement when inserting into the collection e.g.
BEGIN
IF htmldb_collection.collection_exists('INJURED_PERSON') = FALSE THEN
htmldb_collection.create_collection( p_collection_name => 'INJURED_PERSON');
htmldb_collection.add_member(p_collection_name => 'INJURED_PERSON',
p_C001 => :P4_INJURED_FIRST_NAME,
p_C002 => :P4_INJURED_OTHER_NAME,
p_C003 => :P4_INJURED_SURNAME,
p_C004 => :P4_INJURED_SHOP_NO,
p_C005 => replace(:P4_INJURED_BUILDING,':','')
etc.........
but I just don't want to have nested replace statements. Also I'll loose "," and ":" when I retrieve the back off the collection
Does anyone know of a better workaround?
Regards
Paul P

Hi Paul,
Apex uses colons in the url to separate the parameters. You could replace these with another character (for example, ~) and then have a Before Header page process on the second page that converts that back again.
However, as a collection is available until you clear it or log out, you could just pass the SEQ_ID and get the second page to retrieve the values directly into the page items

Special Characters issue in DEV and QAS

Hi,
I am uploading a file that has special characters (Japanese).
In the DEV system the special character is converted to #. Which the business wants.
In QAS system the special character is not converted and is as it is, which makes the business users difficult to find out if any speical characters are there and they don't want the special character as it is
The file consists millions of record with a possibility of four or five records with special characters
The special characters on keyboards is not an issue.
The programs in DEV and QAS system are same and the file tested is also the same but different results.
Tried in Tcode SNLS to find something but didn't know what and where to look into.
What could be the issue in this? Looks like this is Basis issue but would like to know if anyone can let me know.......
Regards
Sandeep

Hi ,
i want to check ur open dataset statement in the program which is being used here if at all in ur case.
Can you please check the relavant code page in both the D and Q systems and search with the appropriate hexa decimal values(for the special characters ) in both the systems ..
u can use code page by tcode scp ..
ex -> as u say a special char sp1 is having entry in q and code page which is being used (like 4200 )
is not having in d03 .
then if in d03 this page has no entry then it shows as # , since it is showing in q then it has an entry over there. this is my guess..
so if at all the client wants not to see this special char's , u need to remove them from this code page.. and check ..
Cant say if this can solve but u can take this as one more way of dealing with code pages and special chars....
br vijay..

Help with Special Characters

Am trying to read in a url that has special characters:
http://intranet.xxx.org/Policies/!SSL!/RoboInfo_Output/Patient_Care_&_Services__(PCS)/Clin ical_Alarms_5-19-04_Final.htm
I'm using ReadURL and have never had any issues before.
When the page is published, the URL stops at the ampersand
and says page cannot be found.
I tried URL Encode and URLDecode with no success.
Any ideas?
Thanks!
Kristin Hill

If you run URLEncode on that URL, what is the result?
If you copy (or type) that result into a browser address
field, does it
work?

Special Characters and Importing .TXT files

I am trying to import a .txt file that has special Characters. The ñ works correct, but the ® does not import correctly. Any Ideas?

What is strange is that if I open the .txt file up on a windows machine the ® is there.
When placing your text file, check the "Import Options" box. You can choose platform, encoding, and, um, um, something else. But you need to specify Windows platform, I think. You might need to specify your encoding as well. You can use an app like TextWrangler or Ultraedit or something else to figure out your text encoding. Or you can use the Drunkard's Walk algorithm: just keep trying encodings randomly until you find the one that works.

XML Parsing Base64 Content - Special Characters Umlaut etc

Hello!
I am currently parsing an XML file which has it's content encoded in Base64. My application parses the XML file (from a provider) and pass on the content to a GUI where the user can change the value of the nodes and store the same back in a new XML (which is then to be sent back to the provider). The Application uses only "UTF-8" . I am currently using the Base64 class provided at http://iharder.net/base64
The problem I have is that the special characters like �, � etc, are being depicted as (?) i.e. unreadable. Only when I control the decoding process i.e. String resoolt = new String (result.getBytes(), "UTF-8") do I get the correct content, and the same can be posted on the GUI.
The application produces an XML file (The application in question is a translation app), which when re-opened in the application for retranslation has the same problem... it is shown with teh special characters with (?).
After a lot of debugging I found that the XML produced by the application does not need the forcing of content into UTF-8 using the code above, it is read automatically correctly (with all the content correct), but due to the coding I have done... String resoolt = new String (result.getBytes(), "UTF-8") the nodes are decoded with the earlier problem umlauts et al missing.
Now I could use a test to differntiate between the two cases XML from the provider or the XML which is produced by my own app, and doesn"t work on the Provider and treat them differently, but I don't want this solution since the XML which my app produces is not accepted as input at the providers.
So my query.. what is the best way to go about it now... I am quite stymied >(
Thanks!

Amazingly enough some other user has the identical problem to yours and has expressed it in exactly the same words. Has the same name as you too.

Error in parsing special characters

We are getting the following error when we parse a clob with special characters like \226(- special dash char), \231(the "TM"-Trademark logo), \256(the "R"-Registered logo )
"Invalid char in text" when the parser is loaded in the db.
But when we tried to parse this xml file as a file input (parser is now outside the db), it parses the file fine and inserts the data into the db.
We are wondering if there is a difference in parser parsing special characters between inside and outside the db.
We are running xml parser version 2.0.2.7 and if this is a bug and being fixed in later version, is there a workaround for this version

Please try our latest 9.0.1 version

How to handle special characters in Apex

Hi ,
In my application I have two regions - one is Report Region (Interactive Report) and other one is HTML region with two text items - Empno and name
My Report has two columns Empno(varchar2) and Ename(varchar2).
When I click the edit link in the report column, the empno should have a read only EMPNO value and ename is a text field with ENAME value.
When I run my application I have encountered the following problems :
1. if my empno has special characters like ' # ', the characters after that is not getting displayed
2. if my empno has special characters like ',' - the characters after comma is treated as a next texitem value
Here is my credential ,

Don't pass data values in URLs. Whilst it is possible to escape values to make them URL- and APEX parameter-safe, it is much better practice to avoid the problem altogether.
Create a surrogate primary key on the table that is an immutable discrete numeric identifier and only use this as a URL parameter. In target pages/regions, use this PK value to retrieve the required data from the table.
