Re: [xsl] Problem with Output special char in HTML attribute

[Robert Koberg <rob@xxxxxxxxxx>]

In addition to what Jeni said (you should able to get the tab count from 
your source?) you can do it by writing to the output stream.

I have had to do something similar, but with JSP 1.2 (the one with no 
Expression Language). Basically, I created some elements in the source, 
like:


<jsp:scriptlet>

String id = someAction.getId();

</jsp:scriptlet>

<jspp:outputElement name="a">
  <jspp:outputAttribute name="href">
    <jspp:concat str_value="next-page.jsp?id="/>
    <jspp:concat var_value="id"/>
  </jspp:outputAttribute>
</jspp:outputElement>

Then the transformation to the JSP (hope you can parse this into PHP) does:


<xsl:template match="jspp:outputElement">
  out.print("<xsl:text disable-output-escaping="yes">&lt;</xsl:text>");
  out.print("<xsl:value-of select="@local_name"/>");
  <xsl:apply-templates select="jspp:outputAttribute" mode="attrOut"/>
  out.print("<xsl:text disable-output-escaping="yes">&gt;</xsl:text>");
  <xsl:apply-templates/>
  out.print("<xsl:text disable-output-escaping="yes">&lt;</xsl:text>/");
  out.print("<xsl:value-of select="@local_name"/>");
  out.print("<xsl:text disable-output-escaping="yes">&gt;</xsl:text>");
</xsl:template>

<xsl:template match="jspp:outputAttribute"/>

<xsl:template match="jspp:outputAttribute" mode="attrOut">
  <xsl:choose>
    <xsl:when test="boolean(@name)">
      out.print(" ");
      out.print("<xsl:value-of select="@name"/>");
      out.print("='");
      <xsl:choose>
        <xsl:when test="boolean(@str_value)">
          out.print("<xsl:value-of select="@str_value"/>");
        </xsl:when>
        <xsl:when test="boolean(@var_value)">
          out.print(<xsl:value-of select="@var_value"/>);
        </xsl:when>
        <xsl:otherwise>
          out.print(<xsl:apply-templates/>);
        </xsl:otherwise>
      </xsl:choose>
      out.print("'");
    </xsl:when>
    <xsl:otherwise>
      <xsl:apply-templates mode="attrOut"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>


<xsl:template match="jspp:concat">

  <xsl:if test="not($context='0')">

    <xsl:if test="preceding-sibling::jspp:concat">
      <xsl:text> + </xsl:text>
    </xsl:if>
    <xsl:choose>
      <xsl:when test="boolean(@str_value)">
        <xsl:text>"</xsl:text>
        <xsl:value-of select="@str_value"/>
        <xsl:text>"</xsl:text>
      </xsl:when>
      <xsl:when test="boolean(@var_value)">
        <xsl:value-of select="@var_value"/>
      </xsl:when>
    </xsl:choose>

  </xsl:if>

</xsl:template>

Let me know if it does not make sense.

best,
