Hello,
I just this question:
Expand|Select|Wrap|Line Numbers
  1.     <xsl:for-each select="//tag1">
  2.       <xsl:value-of select="text()" />
  3.     </xsl:for-each>
  4.  
my output is:
hello;world;
I need:
Hello;
World;

my xslt header is:
Expand|Select|Wrap|Line Numbers
  1.        <xsl:output method="text"                 
  2.                    encoding="iso-8859-1"           
  3.                    indent="yes"                
  4.  
My output file is a text file.....
How can I do this, please?

Best regards,

You can concatenate text() with line feed entity "&#xD;".

Expand|Select|Wrap|Line Numbers
  1. <xsl:template match="/">
  2.    <xsl:for-each select="//tag1">
  3.      <xsl:value-of select="concat(text(), '&#xD;')"/>
  4.    </xsl:for-each>
  5. </xsl:template>

hi thanks,
what do you think if I add it inside a text tag? is this better or not?
Expand|Select|Wrap|Line Numbers
  1. <xsl:text>>&#xD;</xsl:text> 
sometimes I need to do this too:
Expand|Select|Wrap|Line Numbers
  1.  <xsl:text>>printf("hello");&#xD;</xsl:text>  
or indent the braces:
Expand|Select|Wrap|Line Numbers
  1.  <xsl:text>>         } &#xD;</xsl:text>  
What do you suggest for these aims?

Thanks,

I think it's absolutely normal, but variant with concatenation is more readable than your. Compare:

Expand|Select|Wrap|Line Numbers
  1. <xsl:value-of select="concat( 'your_text', text(), '>         }  ', some_tag_value, 'your_text2')"/>
  2.  
and

Expand|Select|Wrap|Line Numbers
  1. <xsl:text>your_text</xsl:text><xsl:value-of select="text()/><xsl:text>>         }  </xsl:text><xsl:value-of select="some_attrib_value"/><xsl:text>your_text2</xsl:text>

thanks,
seem ok, but the function concat(), where I can find explanation about other function too?
Why doens't these below work?
Expand|Select|Wrap|Line Numbers
  1.              indent="yes"           
  2.               xalan:indent-amount="2"/>

It's xalan specific instruction. I think U need to read some docs about it. )

Thanks; a further question if possible....
The text in the xml contains this string inside a tag: "hello\nworld" (and I mean not the new line but the '\' follow by 'n'
Expand|Select|Wrap|Line Numbers
  1. <xsl:value-of select="concat( 'PRINT(', text(), ');'  /> 
  2. //produce in the output file:
  3. PRINT(hello\nworld);
  4.  
while I need in the output text file:
Expand|Select|Wrap|Line Numbers
  1. PRINT(hello);
  2. PRINT(world);
  3.  
How can I do this, please?

<xsl:value-of select="concat( 'PRINT(',
replace(text(), '\n', &#xD;),
');' />

<xsl:value-of select="concat( 'PRINT(',
replace(text(), '\n', &#xD;),
');' />
hello,

it seems there's a problem to put the "(" ")" of replace inside a concat......Do you know it? Is there any trick, please?

thanks,

  2.                                                             replace(text(), '\n',  ), 
  3.                                                           ');' "/>
I forgot double quote at the end of "select" attribute. And you just need to pay attention to the code and read more docs ))

Hello, I don't understand: my code is this
Expand|Select|Wrap|Line Numbers
  1.    <xsl:value-of select="concat('       doc.print(', 
  2.     replace(text(), '\n', '&#xD;' ), ');&#xD;');" disable-output-escaping="yes" />
  3.  
now I'm editing it with .Net and it says that replace() isn't xslt function....
Is it ok ,please?

Guessing you're using XSLT 1.0 then.
You could use a recursive replace function:

http://www.xml.com/pub/a/2002/06/05/transforming.html
for some reason, it won't let me paste the function....

mm I haven't still done this thing; I can't understand how to do the replace() (in my case) with xslt 1.0....any suggests....
I remember...my output file output:
Expand|Select|Wrap|Line Numbers
  1. print(hello\nworld); //"hello\nworld" is the result of text() xslt function
  2.  
Instead I need:
Expand|Select|Wrap|Line Numbers
  1. print(hello);
  2. print(world);
  3.  
That is: xslt should looks into text() and break the string when it sees a '\n';

thanks.

Could you post your input? It might really help to clear things up. I feel like we're forcing an error down a crooked path.

Expand|Select|Wrap|Line Numbers
  1. <root>
  2.     <htmltag><![CDATA[<html>\n<body>]]></htmltag>        
  3.     <text><![CDATA[This is a text node]]></text>    
  4.     <htmltag><![CDATA[.\n</body>\n</html>]]></htmltag>
  5. </root>
  6.  
This is my xml; with xalan and a xslt (as you read before) I have to produce:
Expand|Select|Wrap|Line Numbers
  1. print(<html>);
  2. print(<body>);
  3. ...................
  4.  
at the moment it produce:
Expand|Select|Wrap|Line Numbers
  1. print(<html>\n<body>);
  2.  
THe problem is that '\n' (and at this point the fact that xalan use xslt 1.0 and doens't know replace() )

Are you understand? I dont' understand how write the replace in xslt 1.0....

Put the corresponding print text around anywhere where you output the text.

target is '\n', replacement is '' (empty string)

hello,

there is a problem: $outputString; I suppose I have to set this via Xalan (in java code); but as you can see in my previous code I use text();
With xalan I can do :
trasformer.setParameter("target", '\n' );
trasformer.setParameter("replacement", "" );
but only this and not other...

Are you understand, plese?
