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,

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

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.
/** The method parses the Report Data and applies the Style Sheet to this data

// display any warnings that may occur
processor.showWarnings(true);
// processor.setErrorStream(System.err);
// Process XSL
XMLDocumentFragment result = processor.processXSL(xsl, xml);
return result;
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.

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;

Why does text on certain portions of websites, usually when adjacent text contains special characters, become jumbled into seemingly random sets of characters that are not in any way jumbled when viewing the source of the webpage? How can I fix this?

When viewing most text on most websites, it displays properly. However, there are two instances where text will either tend to, or consistently, become jumbled into a mess of seemingly random characters. Oddly enough, these seemingly random characters are not, in fact, random. The same weird character will be used to replace the same regular English text character consistently across the entire area that has been jumbled.
The two instances where this tends to occur most often, or consistently in some cases, are, first, when a paragraph or particular section of formatted text contains special characters, such as Chinese or Japanese characters, or accented letters. When this happens, usually the paragraph that contains the special characters is completely jumbled, while the rest of the text on the page will have intermittent jumbling on a word or two. Most often, the word "the" is jumbled in this case.
The second instance where this happens is when a website uses specially formatted text in some form or another. I, not being an expert at web development, am not sure what kind of formatting causes it, but I can provide consistent examples in lieu of my experience:
- Example 1:
[http://img408.imageshack.us/img408/9564/firefoxcharencodingissu.jpg]
Example 1 shows a portion of a screen-shot of the website "Joystiq.com". Every single article title on the front page of this blog is consistently jumbled, while the text of the article itself remains untouched. Please note that when this jumbled text is highlighted, it is visible un-jumbled in the right-click menu as well as in the source code of the page. Other consistent instances can be found within many search fields on various websites. For instance, the search bar located at the top right of "Kotaku.com" consistently displays jumbled characters both on its default text of "Search" and on any text that is typed into the search box itself.
- Example 2:
[http://img822.imageshack.us/img822/9564/firefoxcharencodingissu.jpg]
Example 2 shows both the jumbling of the paragraph containing the character "☆" as well as the subsequent peppering of the rest of the article's text with small jumbled words. Below this is the DOM Source of the selected text which shows how the text itself is being rendered properly within the site's source. Additionally, for convenience, I have edited on to the bottom of the image a small snippet of what the search bar on the same page looks like. Notice how the grayed-out text that normally would read "Search" is instead jumbled.
This issue has been plaguing my browser for the past year or so, and I had hoped that it would go away with subsequent Firefox updates. It has not gone away.
Thank you for reading! Please help!

This issue can be caused by an old bitmap version of the Helvetica or Geneva font or (bitmap) fonts that Firefox can't display in that size.
Firefox can't display some old bitmap fonts in a larger size and displays gibberish instead.
You can test that by zooming out (View > Zoom > Zoom Out, Ctrl -) to make the text smaller.
Uninstall (remove) all variants of that not working font to make Firefox use another font or see if you can find a True type version that doesn't show the problem.
There have also been fonts with a Chinese name reported that identify themselves as Helvetica, so check that as well.
Use this test to see if the Helvetica font is causing it (Copy & Paste the code in the location bar and press Enter):
<pre><nowiki>data:text/html,
Helvetica abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ 
Helvetica Neue abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ
</nowiki></pre>
You should reset the network.http prefs that show user set on the about:config page. 
Not all websites support http pipelining and if they do not then you can have issues with images or other problems.

I never used LabView but need to generate a RS-233 serial output string that contains an IRIG timestamp based on a contact closure. Is LabView an appropriate tool to do this? How much does it cost to get started with the product?

I never used LabView but need to generate a RS-233 serial output string that contains an IRIG timestamp based on a contact closure. Is LabView an appropriate tool to do this? How much does it cost to get started with the product?

Labview isn't cheap, but it would certainly allow you to build a program (set of vi's - virtual instruments) that would do what you describe. Where would the timecode information come from? Your vi, or program, would: Start up, initialize the serial port, loop until a trigger happened, read the timecode (from where?), output that timecode out the serial port in a loop until you pressed the stop button. There is a free evaluation of Labview software available from NI - the base product itself runs about $995.

Export Database With Password Containing Special Characters

Hi,
I'm doing a database export using the command:
exp userid=user/pass@instance parfile=exp_parms.dat
The problem is that the password contains special characters so the command fails with a syntax error. The command works perfectly fine when I run it without the password and just type it in when prompted, but I need to include the password in the command because I am running it in a batch file. I've tried using the escape character (\), but this results in a username-password mismatch.
Is there some way of declaring a password containing special characters in the 'exp' command?
...Thanks in advanced!

Hi,
I'm using linux and this is how I did it.
I created a user named ddg with a password ddg)ddg
I did my expdp command like:
expdp ddg/"ddg\)ddg" directory=dpump_dir dumpfile=ddg.dmp
Put the password in double quotes and escape the funny character with a \
Hope this helps.

Column name in a query contains special characters

Hi folks,
The column name in a query contains special characters. For example ~ or ^. The creator of the table put these column names under double quotation while creating the table. When I get the column names form the result set meta data object it returns without quotation. Is there any way to tell the jdbc driver so that it return those column names as it was created, I mean in double quotation.
The help is urgent. I will appreciate any suggestions. Thanks �.
[using oracle driver for 10g]
Thanks
Angelina

Just because the column names were in quotations when the database was created doesn't mean that the quotes are actually part of the names. What's inside the quotes is what makes the column name in the database. If I created a column as "abcd" and put it in quotes just like that ("abcd"), it would go in the database as abcd since SQL would strip off the quotes.
And there's your answer. Just put all column names in quotes whenever you need to talk to SQL. It will strip off the quotes and understand.
I think SQL will also accept square brackets ([ and ]).

Entering passwords containing special characters in Terminal

Whenever I enter a shell command that requires me to verify my password (such as becoming root), my password is never accepted as valid because it contains special characters, such as "é" (I'm assuming that's why, at least). I've tried many times and am positive I'm not typing it incorrectly.
Does anyone know a way around this, or do I have to just create a less exotic password?

Characters typed with the Option key may not translate properly between different encodings; the exact character expected may be a different one, or may not map to anything at all. You shouldn't use Option-keyed characters in a Mac OS X account password.
