Sending XML Content (with < >) as value of an attributes to Object tag in HTML

[Eshrath]

Hi,

What I am trying to do:

I need to form a table in html using the xsl but the table that is formed is quite long and cannot be viewed in our application. So we are writing one object in C# which will take the entire table tag contents and renders. Ie., we need to pass "<table>………… <thead>……</thead>. <tr>.<td> <td>..<tr>.<td> <td> </table>" content to the object using Object tag.

So I have written the xsl as

<object classid="………..">
<xsl:attribute name="HTMLContent">
<xsl:apply-templates select="tgroup"/>
</xsl:attribute>
</object>

Here the HTMLContent is an attribute of the object which will be interpreted by the C# objeect class aptly. "tgroup" template would give the entire table content ( "<table>………… <thead>……</thead>. <tr>.<td> <td>..<tr>.<td> <td> </table>" ).

This XSL should be transformed as

<object classid="……." HTMLContent="<table>………… <thead>……</thead>. <tr>.<td> <td>..<tr>.<td> <td> </table>">

But the table tag value is going as blank to the HTMLContent attribute.
i.e,

<object classid="……." HTMLContent="">

But if I give some thing like

<object classid="………..">
<xsl:attribute name="HTMLContent">
Sample
</xsl:attribute>
</object>

The XSL transforms as

<object classid="……." HTMLContent="Sample">
</object>

I really don't understand why the table content is not getting in to the HTMLContent attribute of Object tag. Is there a way where I can do like this.

I am struck up in this for a long time. Please help me out.

Thanks and Regards,
-Eshrath.

Hi,

Not sure trying to put markup inside an attribute is ever the best idea? I've never used the <object> much - are you sure you can't put the markup as the content in some way (maybe namespaced?).

But anyway, to put markup into an attribute using XSL you will need to do your own escaping of the tags, e.g.

== XML ==============================
<?xml version="1.0"?>
<tgroup>
<table border="1">
<!-- comment -->
<?pi something?>
<thead>hd</thead>
<tr>
<td>1</td>
</tr>
<tr>
<td>2</td>
</tr>
</table>
</tgroup>
== end of XML =======================

== XSL ==============================
<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xslutput method="html"/> <xsl:template match="/"> <html> <body> <object classid="....."> <xsl:attribute name="HTMLContent"> <xsl:apply-templates select="tgroup" mode="esc-start"/> </xsl:attribute> </object> </body> </html> </xsl:template>

<xsl:template match="*" mode="esc-start">
<xsl:apply-templates mode="esced"/>
</xsl:template>

<xsl:template match="*" mode="esced">
<xsl:text>&lt;</xsl:text>
<xsl:value-of select="name"/>
<xsl:apply-templates select="@*" mode="esced"/>
<xsl:text>&gt;</xsl:text>
<xsl:apply-templates mode="esced"/>
<xsl:text>&lt/;</xsl:text>
<xsl:value-of select="name"/>
<xsl:text>&gt;</xsl:text>
</xsl:template>

<xsl:template match="@*" mode="esced">
<xsl:text> </xsl:text>
<xsl:value-of select="name"/>
<xsl:text>="</xsl:text>
<xsl:value-of select="."/>
<xsl:text>"</xsl:text>
</xsl:template>

<xsl:template match="comment" mode="esced">
<xsl:text>&lt;!--</xsl:text>
<xsl:value-of select="."/>
<xsl:text>--&gt;</xsl:text>
</xsl:template>

<xsl:template match="processing-instruction" mode="esced"> <xsl:text>&lt;?</xsl:text> <xsl:value-of select="name"/> <xsl:text> </xsl:text> <xsl:value-of select="."/> <xsl:text>?&gt;</xsl:text> </xsl:template>

</xsl:stylesheet>
== end of XSL =======================

You could etend this further with a template (in mode "esced") that looked for HTML tags that didn't require closing properly (i.e. <br>, <hr>, etc.), e.g. adding the template...

<xsl:template match="*[contains('|br|hr|',concat('|',
translate(name,
'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
'abcdefghijklmnopqrstuvwxyz'),'|'))]" mode="esced">
<xsl:choose>
<xsl:when test="node">
<xsl:text>&lt;</xsl:text>
<xsl:value-of select="name"/>
<xsl:apply-templates select="@*" mode="esced"/>
<xsl:text>&gt;</xsl:text>
<xsl:apply-templates mode="esced"/>
<xsl:text>&lt;/</xsl:text>
<xsl:value-of select="name"/>
<xsl:text>&gt;</xsl:text>
</xsl:when>
<xsltherwise>
<xsl:text>&lt;</xsl:text>
<xsl:value-of select="name"/>
<xsl:apply-templates select="@*" mode="esced"/>
<xsl:text>&gt;</xsl:text>
</xsltherwise>
</xsl:choose>
</xsl:template>
