How to remove empty tags respecting the schema contraints?

Hi,
I'm generating an XML document with XSLT. This document have some empty tags. My question is about to remove all empty tags only if they are defined as optionnals in the schema.
Is this possible with the DOM?
Thanks in advance,
Philippe

With DOM3 validation api, elements/attributes may be checked if they may be removed.
-Check if the element is empty; getFirstChild() method returns null.
-Check if the element may be removed with DOM 3 Validation API.

Dear Odie,
May I make your example a bit more complicated by adding an additional complexType, please:
---Original ----
<DEPT>
<EMPID>1</EMPID>
<EMPNAME>Martin Chadderton</EMPNAME>
<SALARY>??</SALARY>
<SALARYq></SALARYq>
</DEPT>
----- New ----
<DEPT>
<EMPID>1</EMPID>
<EMPNAME>Martin Chadderton</EMPNAME>
<SALARY>??</SALARY>
<SALARYq></SALARYq>
<EMPLMNT_HISTORY>
<DEVISION>1</DEVISION>
<FROM_DATE>2011-01-01 </FROM_DATE>
<TO_DATE></TO_DATE>
</EMPLMNT_HISTORY>
</DEPT>
Your solution works perfectly for <SALARY>, but how would you suggest also to deal with <TO_DATE> ?
Massive thanks for your help!
N.B. Just to emphasise, in my case I have 3 levels (complexType > complexType > complexType) and many elements and I would like to know if there is any generic option to say
to remove all the empty elements from the result, as it causes to the SSJ (Systinet) Webservice to crash.

How to remove empty tags from a config file

Hi all,
I have a task where we need to run a Java program to remove tags which do not contain ny information from the config files. The format of the file is as under:
<roleManager>
     <providers>
          <add name="AspNetSqlRoleProvider" b03f5f7f11d50a3a" />
          <add name="AspNetWindowsTokenRoleProvider" PublicKeyToken=b03f5f7f11d50a3a" />
     </providers>
</roleManager>
<httpModules>
</httpModules>
In the above lines <roleManager> is a tag which contains some data, while <httpModules> is an empty tag and does not conatin any data. The resultant should be:
<roleManager>
     <providers>
          <add name="AspNetSqlRoleProvider" b03f5f7f11d50a3a" />
          <add name="AspNetWindowsTokenRoleProvider" PublicKeyToken=b03f5f7f11d50a3a" />
     </providers>
</roleManager>
Please suggest how can we achieve this?
Thanks in advance

I ususally do that type of thing with a state machine... read a token, look for what is next, and if it's the closing token, I don't write it out. You have well defined opening token syntax and closing token syntax, so it should be relatively easy.

How to remove empty tag.

Hi,
I have a scenario IDOC-XI-JDBC
From IDOC we are using change pointers and when something has been changed then those fields are being sent out but other few empty fields were coming out and to avoid that I used mapWithDefault to avoid the empty tags as target system used to error out.
But now when any field is empty coming from change pointer is also being caught in mapWithDefault....whereas it is expected to send blank.
Can anyone of you suggest any solution.
Regards
Ria

Hi Ria,
You can use if without else and check the field exist or not in the source and then map it to target.
This is a bit tricky & if you dont feel comfortable with it, then use advanced UDF, and explicitely check ResultList.SUPPRESS object and remove it in UDF and form an output stream.
You can use any of the two.
Regards,
Shri.

How to remove html tags from the pdf file ?

Hello,
Using BI publisher we are generating a pdf file. In the table, we have data which contains html tags. for example " test1<br> 2.test2<br> 3.test3<br> ".
In the pdf file we need to get the output like this
test1
test2
test3
But the output is as follows :"test1<br> 2.test<br> 3.test3<br> "
Any idea, how these html tags can be removed from the pdf file and obtain the required result?
Thanks in advance!!
Archana

Archana,
Can you wrap your code in <code> tags (use square brackets rather than angled ones), as the forum software is interpretting the HTML tags, in other words we can't see what you mean ;)
In any case, there are a few different options (guessing at what your problem is, without seeing the actual data), you could use htf.escape_sc or replace, regexp_replace etc to substitute the values before you output them to your PDF.
Hope this helps,
John.

How to remove blank spaces in the source code of my page?

I created a page with the following code for testing:
<dsp:page>
<dsp:importbean bean="/atg/commerce/catalog/ProductLookup"/>
     <dsp:droplet name="ProductLookup">
          <dsp:param name="id" value="xprod2046" />
          <dsp:param name="elementName" value="product" />
          <dsp:oparam name="output">
               <dsp:valueof param="product.DisplayName"/>
          </dsp:oparam>
     </dsp:droplet>
</dsp:page>
It only shows the product name in the browser. But if I look at the source code of my page he created 61 lines in response to this code, where a line is the product name and the other 60 have nothing.
I know how to remove these lines that the ATG creates no content because my project is full of these empty lines.
Anyone ever had this problem and could help me?
Thanks

Hi ,
Yup this is a problem ,
you can use following ways :
1- use jsp comments eg :
<dsp:page>
<dsp:importbean bean="/atg/commerce/catalog/ProductLookup"/><%--
     ----%><dsp:droplet name="ProductLookup"><%--
          ----%><dsp:param name="id" value="xprod2046" /><%--
          ----%><dsp:param name="elementName" value="product" /><%--
          ----%><dsp:oparam name="output"><%--
               ----%><dsp:valueof param="product.DisplayName"/><%--
          ----%></dsp:oparam><%--
     ----%></dsp:droplet><%--
----%></dsp:page>
2- End tags at next line :
e g :
* <dsp:page
* ><dsp:droplet name=”xyz”
* ><dsp:oparam name=”output”
* >Name: <dsp:valueof param=”abc”
* /></dsp:oparam
* ></dsp:droplet
* ></dsp:page>
3- Always use TAB instead of using SPACEBAR whie writing source code.
4 - From JSP 2.1 onwards we have a page directive trimwhitespaces ( see if that works , i was not able to ), google for it for more info
5 - You can modify your build scripts to remove white spaces from jsps while building EAR.(complex though, as you may not want to trim all white space.)
6 - modifying the deployment descriptor.
<init-param>
<param-name>trimSpaces</param-name>
<param-value>true</param-value>
</init-param>

How to remove 'Empty Demarcation' in Text Elements.

Dear All,
To remove 'Empty demarcation' in the WAD output, I had modified the standard program - SAPLRSSV (for this i took access key from SAP).
The text element : 301 was changed to blank and it worked.
Recently we had a support package upgrade to SAPKW70018. With this upgrade my previous change to the program got reverted back and so i need to do the change again.
However, I'm not able to retrieve the list of Text elements for this program (SAPLRSSV). I open the program and when i go to Text element, following message is displayed :
"Untranslated texts from master language DE will also be displayed"
But no list (no text elements) is displayed.
My question : How do i retrieve this list and can i use the same acess key again or do i need to take another one from SAP.
Regards,
Nagendra.

Sorry, I was referring to the incorrect program SAPLRSSV instead of SAPLRRSV. The problem has been resolved.
Regards,
Nagendra.

You have to remove it simply. Try to grab the card and move it out. You can try to use the pair of tweezers. Maybe it helps

How to remove links pointing to the same page?

I have PDF documents with Links which point to sections referenced (e.g. link of text "Section 2.2" points to the actual page number of "Section 2.2"), but as the links are created from cross-references during rendition from Word to PDF, there are cases that the destination page number and source page number of the links are the same (e.g. links of text "Section 2.2" on page 9 are created with the destination of page 9 which is the actual page number of "Section 2.2"), I want to remove all these links, but I don't know how to get the destination page, I check the API reference and find that "PDLinkAnnotGetAction" may work , but I don't know how to use it, could you check me codes below and advise ? Your help is really appreciated!
PDPage page;
ASInt32 i,i2;
AVDoc avDoc = AVAppGetActiveDoc();
PDDoc pdDoc = AVDocGetPDDoc (avDoc);
int pageNum = PDDocGetNumPages(pdDoc);
for (i = pageNum - 1; i >= 0; i--)
page = PDDocAcquirePage(pdDoc, i);
int annotNum = PDPageGetNumAnnots(page);
for (i2 = annotNum - 1; i2 >= 0; i2--)
if...
PDPageRemoveAnnot(i, i2);
My Product Information:
Acrobat Pro 8.1.6, Windows

Start by reading the PDF standard (ISO 32000-1) to understand Actions vs. Destinations.
Then for each annot, you'll want to see which it has (and in the case of an Action, if it has more than one). Then you need to parse the action or dest to see what it is and where it goes. If you don't like it, then you'll delete it.

How to remove "all day" as the default setting in iCal?

How to remove "all day" as the default setting in iCal? The iCloud calendar works by double-clicking but the local behaves differently.

Hello Valerie,
the default - "all day" or "time based" - depends on the view in iCal. In month view the default is "all day",
in week view or day view it is a time interval, if you use "File -> New Event". If you add the event by double clicking into the calendar, it will depend on the section you are clicking - in the all day section you will add an all-day event, in the time-grid you will enter an event with start-end time.
