xsl:foreach

[mickey0]

Hello,
I just this question:

    <xsl:for-each select="//tag1">
      <xsl:value-of select="text()" />
    </xsl:for-each>
 

my output is:
hello;world;
I need:
Hello;
World;

my xslt header is:

       <xsl:output method="text"                 
                   encoding="iso-8859-1"           
                   indent="yes"                
 

My output file is a text file.....
How can I do this, please?

Best regards,

[roces]

You can concatenate text() with line feed entity "
".

<xsl:template match="/">
   <xsl:for-each select="//tag1">
     <xsl:value-of select="concat(text(), '&#xD;')"/>
   </xsl:for-each>
</xsl:template>

hi thanks,
what do you think if I add it inside a text tag? is this better or not?

<xsl:text>>&#xD;</xsl:text> 

sometimes I need to do this too:

 <xsl:text>>printf("hello");&#xD;</xsl:text>  

or indent the braces:

 <xsl:text>>         } &#xD;</xsl:text>  

What do you suggest for these aims?

Thanks,

[roces]

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

<xsl:value-of select="concat( 'your_text', text(), '>         }  ', some_tag_value, 'your_text2')"/>
 

and

<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?

             indent="yes"           
              xalan:indent-amount="2"/>
 

[roces]

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'

<xsl:value-of select="concat( 'PRINT(', text(), ');'  /> 
//produce in the output file:
PRINT(hello\nworld);
 

while I need in the output text file:

PRINT(hello);
PRINT(world);
 

How can I do this, please?

[roces]

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

[mickey0]

<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,

[roces]

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

I forgot double quote at the end of "select" attribute. And you just need to pay attention to the code and read more docs ))

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

Hello, I don't understand: my code is this

   <xsl:value-of select="concat('       doc.print(', 
    replace(text(), '\n', '&#xD;' ), ');&#xD;');" disable-output-escaping="yes" />
 

now I'm editing it with .Net and it says that replace() isn't xslt function....
Is it ok ,please?

[jkmyoung]

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....

[mickey0]

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:

print(hello\nworld); //"hello\nworld" is the result of text() xslt function
 

Instead I need:

print(hello);
print(world);
 

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.

<root>
    <htmltag><![CDATA[<html>\n<body>]]></htmltag>        
    <text><![CDATA[This is a text node]]></text>    
    <htmltag><![CDATA[.\n</body>\n</html>]]></htmltag>
</root>
 

This is my xml; with xalan and a xslt (as you read before) I have to produce:

print(<html>);
print(<body>);
...................
 

at the moment it produce:

print(<html>\n<body>);
 

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)

[mickey0]

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?
