Output to text

Hi,

I am building a javascript menu tree based on some XML and using XSLT with SAXON 8.8.

My XML is as follows:

Code:

</ACM:SEC1>
    <ACM:TITLE>DE-ICING PROGRAM <FARREF>121.689</FARREF></ACM:TITLE>
</ACM:SEC1>

By XSLT is:

Code:

                        <xsl:for-each select="/ACM:ROOT/ACM:CHAPTER/ACM:SEC1">
                            <xsl:variable name="section1">
                            <xsl:value-of select="ACM:TITLE/text()"/>
                            </xsl:variable>
                            <xsl:text>d3 = CreateTreeItem( d2, "img/project.gif", "img/folder_open.gif", "</xsl:text>
                            <xsl:value-of select="$section1"/>
                            <xsl:text>", "</xsl:text>
                            <xsl:value-of select="$section1"/>
                            <xsl:text>.xml", "main" )</xsl:text>;
                        </xsl:for-each>
                    </xsl:for-each>

Desired output =

Code:

d3 = CreateTreeItem( d2, "img/project.gif", "img/folder_open.gif", "DE-ICING PROGRAM", "DE-ICING PROGRAM.xml", "main" );

Current Output:

Code:

d3 = CreateTreeItem( d2, "img/project.gif", "img/folder_open.gif", "DE-ICING PROGRAM 
            ", "DE-ICING PROGRAM 
            .xml", "main" );

The problem is if there is an element child of <ACM:TITLE>, the text output places a line return. How can I avoid this?

You can call normalize-space() to get rid of the trailing spaces and newline, but I don't know what you want to do about the embedded space.

I think there must have been a newline before <FARREF> in your input for this effect to occur.

If you want to escape white space inside of JavaScript string literals then you can use the replace function XPath 2.0 offers: http://www.w3.org/TR/xpath-functions/#func-replace

So for instance replaces

Code:

replace('#10;', '\n', '\\n')

replaces each newline character with \n, the JavaScript escape sequence for newline.

Thanks to both of you for your help.

Code:

<xsl:variable name="section1">
                                <xsl:value-of select="normalize-space(ACM:TITLE)"/>
                            </xsl:variable>

Works like a charm!

Thanks

Even better would be

<xsl:variable name="section1" select="normalize-space(ACM:TITLE)"/>

It's one line of code instead of three, and it defines the variable as a string rather than a result tree fragment, which is a much simpler object that is likely to require much less system overhead.
