xslt -- disable-output-escaping="yes" question

[Veronica Damian]

I need to know all <xsl:...> elements where it's ok to put
disable-output-escaping="yes".. found out this morning can put it inside <xsl:value-of select....> but where else?

and converesely, would like to know all stuff that can be put inside <xsl:text>...</xsl:text>
because if I do <xsl:text disable-output-escaping="yes">and try to put other stuff in there like,

<xsl:call-template name="str-replace">
<xsl:with-param name="input" select="/Presentation/@DisclaimerText"/>
<xsl:with-param name="search-string" select='$NEWLINE'/>
<xsl:with-param name="replace-string" select="<br/>" />
</xsl:call-template>
</xsl:text>

it doesn't work

I need to replace whitespace that is a linebreak with '<br>' but also need to escape the "<" and ">" how do I do this pls... tried:

<xsl:call-template name="str-replace" disable-output-escaping="yes"/>

and

<xsl:with-param name="replace-string" select="<br/>" disable-output-escaping="yes"/>

but neither one worked.. (when I say didn't work I mean get errors when doing the transformation)

this char-escaping-thing is proving to be most complicated thing for me in xslt..

thank you very much...

It only makes sense to have a disable-output-escaping attribute on elements that are actually doing output of text. As far as I can see that's only xsl:value-of and xsl:text, but I would encourage you to look at one of the many sites on the Internet that provide XSLT tutorials and XSLT documentation, if you want to look through all of the xsl: elements.

If you are saying that

<xsl:with-param name="replace-string" select="<br/>" />

causes errors, that's because you didn't escape the < and > characters in the "select" attribute correctly. You have to write this instead:

<xsl:with-param name="replace-string" select="&lt;br/&gt;" />

Then, your best bet is to have some code like this:

<xsl:variable name="replaced">
  <xsl:call-template name="str-replace">
  ... etc ...
  </xsl:call-template>
</xsl:variable>
<xsl:value-of select="$replaced" disable-output-escaping="yes"/>

(Edited to disable output escaping in examples of how to escape < and >)

This PDF has a list of when it is possible to use it:

http://www.mulberrytech.com/quickref/XSLT_1quickref-v2.pdf

I have it print out of this on my desk, and its probably worth its weight in gold - you won't find a higher concentration of useful XSL stuff on two sheets of paper!

thank you very much... (yes I had made mistake when printed <br> in my post, of course I meant

<xsl:with-param name="replace-string" select="<br/>"/>

so now have:

<xsl:variable name="replaced">
<xsl:call-template name="str-replace">
<xsl:with-param name="input" select="/Presentation/@DisclaimerText"/>
<xsl:with-param name="search-string" select='$NEWLINE'/>
<xsl:with-param name="replace-string" select="<br/>"/>
</xsl:call-template>
</xsl:variable>
<xsl:value-of select="$replaced" disable-output-escaping="yes"/>

however, now I get following error:

Error occurred while compiling stylesheet '<fileName>.xslt'.

Code: 0x80004005
Expression expected.

--><<--br/>

I can't find this string (or even just "--br" in xslt or xml.. compiler does not say on what line error occurs, this is a bit of a pain.. I know issue about which I posted my orig post is causing this, b/c if for testing purposes I do

<xsl:with-param name="replace-string" select="aaa"/>

instead of

<xsl:with-param name="replace-string" select="<br/>"/>

don't get error anymore.. would appreciate any suggestions.. thank you very much..

(thank you very much Dave, for that PDF...)

my gosh I see what happens here.. this prints wrong in this mesasge...
meant:

<xsl:with-param name="replace-string" select="& l t ; br / & g t ; "/>

(I thought it was weird, I knew I had copied it ok..)

ok, you get my drift.... I hope.. thanks again..
