Hi guys, how are you?
I need help in a very simple question!
i have this part of the code:
<!-- Searching Metatags -->
<xsl:for-each select="document('arquivos/meta_tags.xml')">
<xsl:value-of select="metatags/tags" disable-output-escaping="yes"/>
<xsl:value-of select="metatags/layout" disable-output-escaping="yes"/>
</xsl:for-each>
As you can see, he seeks out the meta tags of an XML file using CDATA, so far so good...
But the meta description will have to have a random value, seeking another xml ... it will be a mix between the title and description, limited to 155 characters
I tried to do as follows:
I created a variable, and try to apply it within the code ...
<xsl:variable name="desc">
<xsl:for-each select="loja/produto[id_produto = $produto]">
<xsl:value-of select="title" />
<xsl:value-of select="description" />
</xsl:for-each>
</xsl:variable>
and tried to apply it at the end of the loop:
<!-- Searching Metatags-->
<xsl:for-each select="document('arquivos/meta_tags.xml')">
<xsl:value-of select="metatags/tags" disable-output-escaping="yes"/>
<xsl:value-of select="normalize-space(substring($desc, 1, 155))" disable-output-escaping="yes"/>
<xsl:value-of select="metatags/layout" disable-output-escaping="yes"/>
</xsl:for-each>
But I can not put the variable within the meta tag, because that would end the loop, have something like:
<meta name="description" content="$desc{here is the value of $desc}" />
but gives error = /
can anyone help me?
thanks a lot!
