Xslt conditional to limit words in a feed

I'm trying to use XSLT in DW to do a news feed and can't
figure out how to limit the number of words in the description. I'm
using David Power's book as an example. I'm showing the Titles as
links and the Descriptions fine and can limit the number of objects
to display. But I can't figure out how to limit the number of words
in the Descriptions. I want to display the feed in a sidebar and
just show the first couple of lines from the description as a
teaser.
Any suggestions appreciated.

My knowledge of XSLT is pretty basic, so I can't suggest a
way to select
a specific number of words. However, it's very easy to select
the first
sentence. The following example cuts off the contents of a
<description>
tag at the first period followed by a space, and adds an
ellipsis:
<xsl:value-of select="substring-before(description, '.
')"/>
<xsl:text>...</xsl:text>

Help required on XSLT Conditional Mapping

Hi,
We need help on XSLT mapping in BPEL based on a condition. We are transforming from OAG format to a client specific format. We need to map a single tag (but repetitive) on the left hand side (OAG) to different tags on the right hand side. The same tag on the left hand side repeats with different values. Depending on the value the mapping to the right hand side varies. The left hand side (OAG) looks something like this.
<PARTNER>
<PARTNRID>2002</PARTNRID>
<PARTNRTYPE>Supplier</PARTNRTYPE>
<ADDRESS>
<ADDRLINE index="1">2000 Century Way</ADDRLINE>
</ADDRESS>
</PARTNER>
<PARTNER>
<PARTNRID>204</PARTNRID>
<PARTNRTYPE>BillTo</PARTNRTYPE>
<ADDRESS>
<ADDRLINE index="1">90 Fifth Avenue</ADDRLINE>
</ADDRESS>
</PARTNER>
Please note that the tag PARTNER and it's underlying tags appear twice in the XML file.
Based on the value in the tag PARTNRTYPE, the mapping to the right hand side differs. If the value is 2002, PARTNRID should map to Supplier ID on the right hand side and if the value is 24, PARTNRID should map to BillTo ID on the right hand side. The right hand side should look something like
<Supplier>
<SupplierID>2002</SupplierID>
<Address>2000 Century Way</Address>
</Supplier>
<BillTo>
<BillToID>204</BillToID>
<Address>90 Fifth Avenue</Address>
</BillTo>
Please let us know how to achieve this. Your help is much appreciated. Thanks in advance.
Thanks,
Prasanna

Hi Prasanna ,
I am not an expert but what about this:
<SUPPLIERID>
<xsl:value-of select="/PARTNER/PARTNRID[../PARTNRTYPE = '2002']"/>
</SUPPLIERID>
<BILLTOID>
<xsl:value-of select="/PARTNER/PARTNRID[../PARTNRTYPE = '24']"/>
</BILLTOID>or
<xsl:choose>
<xsl:when test="/PARTNER/PARTNRTYPE = '2002'">
    <SUPPLIERID>
      <xsl:value-of select="/PARTNER/PARTNRID"/>
    </SUPPLIERID>
</xsl:when>
</xsl:choose>
<xsl:choose>
<xsl:when test="/PARTNER/PARTNRTYPE = '24'">
    <BILLTOID>
      <xsl:value-of select="/PARTNER/PARTNRID"/>
    </BILLTOID>
</xsl:when>
</xsl:choose>Regards Pete

Limit words for a comment cell

Hi All,
I have a coloum in the last in all data forms to enter comments basically I am using No account for the user to enter the text here. The problem is I want to limit the comment cell to a particular word limit
say for ex 100 words. Kindly sugguest if there is any way to limit the words in a data form
Thanks in advance,

Hi Pavan,
In order to modify particular cells in WAD you would need to use the table interface. Refer to this document:

Change error message to warning during pricing condition upper limit check.

Hi All,
I have a header condition ZFMN to which maximum amount that can be entered is set to $5000. When I enter the amount greater than this, it gives me error message.
Could we change it to warning message?

During Creation of PO when you click PO Check, What Include you are using.
Cann't you use the BADI ME_PROCESS_PO_CUST and write the code whatever you want in PO_CHECK,
There during Check you use any FM POP_TO_CONFIRM OR POP_TO_INFORM or show any information Message too.
Try it once.
Thanks

XSLT include level limit

I have an XSLT file that an xml file is referring to.
The XML file calls the XSLT with this line:
<?xml-stylesheet href="page.xslt" type="text/xsl"?>
The "page.xslt" then includes another xslt file called "widgets.xslt"
"widgets.xslt" has about 10 other xslt files included within it. From what I have found, it seems that Safari will not include any other files after the third level (within the widgets.xslt file)
If I put the includes that I have within the "widgets.xslt" file directly into "page.xslt" everything works. If I don't than the page is blank.
Also, I though maybe something was wrong with the "widgets.xslt" file, so I tried to just put plain XSLT (no includes) in it to see if it still transforms. When I do this the page works.
So my conclusion is that Safari only supports 3 levels of included xslt files. Is this true? is there something I can do to fix this. Does anyone have an answer?
P.S. This works in Firefox 2.0/OS X, Firefox 2.0/Windows, IE6 and IE7 (I am using Safari 2.0)

Conditional tag identifier in Word?

I am looking for a possibilty to define conditional tags in my connected Word documents via the Word style-definitions. Does anyone know whether that is possible an how?
Could not find any hint in the documentation.
Thx!

I've just found a reference to the following methods for applying conditional text in Word:
* Styles with hidden text using different templates
* "includetext" fields that take content from different sub-documents
* Macro-controlled conditionals
* The IF field
I have no experience of using any of these though. I have also not tested whether these would come across into the RoboHelp output when you update the link. You'd also have the issue of training your users on how to set this up and use it. It doesn't sound like a totally straightforward end user task.

Automatic Form Feed - Epson LQ - 2180 printer to R12 in Solaris Environment

Hi
We are adding a new Epson dot matrix [ Impact] Printer to our system. [Epson LQ - 2180]
Server OS: Sun OS sun4v sparc SUNW,SPARC-Enterprise-T5120
R12 Version: 12.1.3
This is a network printer. This has been added to the printer server via root. We have configured the Printer in the Front end also via Install -=-> Printer in System Administrator REsponsibility.
Our goal is to print three programs serially one after the other at a time. The paper input feed is continuous sheet.
When we print from normal windows applications like notepad and MS-word, the page feed / form feed automatically gets set after each request. So that each request gets started in a New page. But this is not the case when we try to do the same from EBS.
Is there any special setting / value that we need to set in the Printer Drivers like Arguments, Initialization and reset.
We referred the printer manual but could not find any specific command or value to be set for Solaris.
Your help is very much appreciated.
thanks

Please see if below metalink note helps you:-

XSLT Mapping: Insert href to other XSLT

Hi eevrybody,
we have an XSLT that generates an XML. The generated XML should have an reference to another XSLT.
With other words: The generated XML has to look like:
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="X:\path\path\AnotherXSLT.xslt"?> // how do do that?
<ROOT> ......
How can we do that?
Thanks Regards Mario

Hi
Try
<xsl:processing-instruction name="xml-stylesheet">href="X:\path\path\AnotherXSLT.xslt" type="text/xml"</xsl:processing-instruction>
this should be deifned in the top level template e.g.
<xsl:template match="/">
<xsl:processing-instruction name="xml-stylesheet">href="X:\path\path\AnotherXSLT.xslt" type="text/xml"</xsl:processing-instruction>
</xsl:template>

Applying LIMIT (dimen.) TO TOP (...) BASEDON (...) structure in OLAP_TABLE

Hi
I'd like to know how to apply structure
LIMIT dimension TO TOP (number of top member performers) BASEDON (measure)
in OLAP_TABLE.
For instance I have a cube SALES with 2 measures: SALES_VALUE and QUANTITY and a dimension PRODUCT with two levels: TOTAL and PRODUCT_NAME. Then I want to list 3 products with the highest SALES_VALUE and QUANTITY > 100.
I can create for example such query:
SELECT sales_val, quant, product_dsc
FROM TABLE(OLAP_TABLE(
'test_schema.test_aw DURATION SESSION',
null,
null,
MEASURE sales_val FROM sales_value
MEASURE quant FROM quantity
DIMENSION product WITH
HIERARCHY product_parentrel
INHIERARCHY product_inhier
ATTRIBUTE product_dsc FROM product_description
ROW2CELL r2c'))
WHERE
OLAP_CONDITION(R2C, 'LIMIT product TO product_levelrel eq ''PRODUCT_NAME''', 1)=1
AND OLAP_EXPRESSION_BOOL(R2C, ' quantity gt 100')=1
AND OLAP_CONDITION(R2C, 'LIMIT product TO TOP 3 BASEDON sales_value, 1)=1; ???????
Instruction above does not work completely well, because it will give 3 rows with top values of SALES_VALUE measure, but in this case OLAP_CONDITION(R2C, 'LIMIT product TO product_levelrel eq ''PRODUCT_NAME''', 1)=1 is not fulfilled (row with values of TOTAL_PRODUCT level appears).
One can create such query:
SELECT sales_val, quant, product_dsc
FROM TABLE(OLAP_TABLE(
'test_schema.test_aw DURATION SESSION',
null,
*'LIMIT product TO TOP 3 BASEDON sales_value', ?????*
MEASURE sales_val FROM sales_value
MEASURE quant FROM quantity
DIMENSION product WITH
HIERARCHY product_parentrel
INHIERARCHY product_inhier
ATTRIBUTE product_dsc FROM product_description
ROW2CELL r2c'))
where
OLAP_CONDITION(R2C, 'LIMIT product TO product_levelrel eq ''PRODUCT_NAME''', 1)=1
AND OLAP_EXPRESSION_BOOL(R2C, ' quantity gt 100')=1;
It leads to the same result as the first query.
What shuold I do to make OLAP_CONDITION(R2C, 'LIMIT product TO product_levelrel eq ''PRODUCT_NAME''', 1)
fulfill in query above?
I can add that query below works as it should (LIMIT TO TOP... omitted).
SELECT sales_val, quant, product_dsc
FROM TABLE(OLAP_TABLE(
'test_schema.test_aw DURATION SESSION',
null,
null,
MEASURE sales_val FROM sales_value
MEASURE quant FROM quantity
DIMENSION product WITH
HIERARCHY product_parentrel
INHIERARCHY product_inhier
ATTRIBUTE product_dsc FROM product_description
ROW2CELL r2c'))
WHERE
OLAP_CONDITION(R2C, 'LIMIT product TO product_levelrel eq ''PRODUCT_NAME''', 1)=1
AND OLAP_EXPRESSION_BOOL(R2C, ' quantity gt 100')=1;
Thank you in advance for any help
Peter

Peter, Yes, I hadn't considered the condition sales_value greater than 100 in my mail.
You can try either of the below limit cmds to include that condition too:
limit product to limit(limit(limit(product to (product_levelrel eq 'PRODUCT_NAME') AND (sales_value gt 100)) keep top 3 basedon sales_value) sort top 3 basedon sales_value)
-or-
limit product to limit(limit(limit(limit(product to product_levelrel eq 'PRODUCT_NAME') keep sales_value gt 100) keep top 3 basedon sales_value) sort top 3 basedon sales_value)
I dont think one can be sure that having separate olap_condition filters for each condition will work fine all the time. To simulate the cascading of AND operations of where clause (filters) in SQL, we can use the nested limit() function to act on progressively smaller/better qualified resultsets (cells). SQL query would apply the AND filters in any manner or order that the optimizer deems fit whereas using the limit function with keyword "keep" within it indicates an implicit order of filters. SQL query with multiple olap_conditions might rank and find top 3 -or- bottom 5 before it applies the filter "sales_value gt 100". In such a case, you may find that the query will return no rows or return only the top 1 or 2 out of top 3 which are gt 100 -or- in case of bottom, return no rows or return less than 5 members (only those above 100) -- not necessarily 3 "top 3" or 5 "bottom 5" members.

So it is serial. This makes it hard to know when the "word" starts....
If you manage to determine a start condition for the "word", it is simple a series of Highs and Lows which has to be analyzed by your software.
You should acquire the data with a buffered method (either finite or continuous which is hardware timed).
hope this helps,

Problems with alignment when printing a mail merge envelope in Word 2013

I am using Mail Merge in Word 2013 to print approximately 100 envelopes, size #10 landscape (9.5" x 4.12"), with a return and recipient address. But when it goes to print, the alignment is completely wrong: it prints the recipient address
at the "top" of the envelope, and the return address is completely cut off. I have everything set up correctly in the document file and can preview each one of my envelopes. Everything looks great on the screen, but the envelopes will
not print correctly.
I have verified Word's printer feed method (by going to Envelopes > Feed > Printing Options) so that it matches how the blank envelopes are sitting in my printer tray. I have verified in both Word and on my printer setup that the #10 envelope
is the correct paper shape/size. I have verified the document's orientation (landscape) and the margins. However, the envelopes still do not print in alignment with how they appear on the screen. I've tried changing the printer feed method
and the position of the envelope, but it prints the same way every time -- regardless of which feed direction I choose in Word. The recipient address is always too high up on the envelope, and the return address is completely cut off.
On a hunch, I inserted a plain sheet of 8.5" x 11" paper and printed the "envelope" on that. Sure enough, Word prints the document as if the envelope were glued to the upper right corner of the sheet of paper. (As in, if I
attached the #10 envelope to the upper right corner of the sheet of paper, all of the fields would be correctly aligned.)
How do I fix this and get the envelopes to print correctly? Please remember that I have tried changing the printer feed method (the direction the envelopes go into the printer) on Word, which has no effect on how the document ends up printing.
Thank you for your help!

Hi,
We would suggest that you do any of the following:
Update your printer driver.
Go back to the
Printing Options
tab of the Envelope Options
dialog box, and make adjustments to the printing options. Print the envelope again. Repeat this process until you discover a configuration of printing options that yields the results that you want.
You may also follow this article steps to Create and print a single envelope test if it works:

Importing images in Word Doc

My colleague recently had Office 2007 installed, then RH 7.
She started a new project and imported a Word *.docx file. RH
did everything I expect it to do except for this:
The images do not appear in the topics. It creates a separate
project manager folder for the images, as I expect it to do.
However, the folder seems to contain nothing. Normally, I
would expect to see images listed there. They aren't in the top
directory as baggage files, either. They are in .gif and .jpg
formats.
The images do show up in the project's Windows directory, in
the new folder corresponding to the "empty" directory in project
manager. The Unused Files report finds them.
I can't figure out what my colleague may have done when built
the Word .doc -- nothing any different from what I usually do --
that could explain this. Saving it as .docx or as .doc makes no
difference. Converting it from .docx to .doc doesn't fix it. The
import goes exactly the same on my two PCs. One runs Office 2007
and RH 7. The other runs Word 2003 and RH 7. Of course, .docx won't
run in the latter environment. Any .docx or .doc files that I built
work fine.
I found two workarounds, but first I'd really like to know
what conditions in her Word files would cause RH to do this. Has
anyone seen it, and is there a simple way to fix the Word doc?
Otherwise these are her options:
Option 1. Create a new Word document in Word 2007 and insert
the complete original file (the new Word menu moved this to Insert
> Object > Text from File). Save the new file as .doc or
.docx. Import the new file into RH 7. Images appear in the topics
and in the project manager under a new folder. (Copy all and paste
into the new Word doc also works.)
She has several large Word documents to deal with, so this is
less than ideal.
Option 2. In the new topics in RH, insert the images where
they belong. While they don't appear in the project manager, the
insert image dialog finds them. After we insert an image, RH shows
it in the project manager. Probably, this would take longer than
Option 1.
Any ideas?

Next time you have trouble importing a legacy Word .doc, try
this:
In Word, create a new file using the New command and the
default .dot.
Insert the contents of the legacy .doc from the menu command
(not by cutting and pasting).
In Word 7, they moved the "insert file" command to Insert
> Object > Text from File . . .
I'd think "insert text from file" would mean pasting
something that doesn't include graphics. However, Word will bring
in everything from the legacy .doc including formatting and styles.
Save As . . . the new document as .doc or .docx. I don't
think RH 7 cares. In our experience, jpegs and gifs sometimes were
missing until we created the new Word file.
Another wrinkle: In Explorer view, with a folder open, File
> New allows you to create an empty Word document right there.
We had some trouble using one of these for importing and saving the
legacy .doc.
Didn't have time to track it down. Was the legacy .doc
created in Word 2003, and the conversion to .docx in 2007 glitched
some images? In your case, it just happened to the .png files? As
you previously speculated, images may have been handled differently
in creating the original .doc.
My hypothesis here is, whatever the reason for images getting
lost in the import to Word, everything gets fixed -- even for pngs
-- when you start with a clean slate in a new Word document created
from the New menu in Word.
