Hallo all,

my project manager wanted from me to build a generelized template for date check. What I have already done was something like that.

<xsl:template match="messagedate" name="messagedate">
        <xsl:variable name="messageDate">
            <xsl:value-of select="./messagedate"/>
        </xsl:variable>
        <xsl:variable name="cc">
            <xsl:value-of select="substring($messageDate,1,2)"/>
        </xsl:variable>
        <xsl:variable name="yy">
            <xsl:value-of select="substring($messageDate,3,2)"/>
        </xsl:variable>
        <xsl:variable name="mm">
            <xsl:value-of select="substring($messageDate,5,2)"/>
        </xsl:variable>
        <xsl:variable name="dd">
            <xsl:value-of select="substring($messageDate,7,2)"/>
        </xsl:variable>
        <xsl:variable name="HH">
            <xsl:value-of select="substring($messageDate,9,2)"/>
        </xsl:variable>
        <xsl:variable name="MM">
            <xsl:value-of select="substring($messageDate,11,2)"/>
        </xsl:variable>
        <xsl:variable name="SS">
            <xsl:value-of select="substring($messageDate,13,2)"/>
        </xsl:variable>
        <xsl:choose>

            <xsl:when test="number($cc) &gt;20 or number($cc)&lt;19 ">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">cc</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be either 19 or 20</xsl:attribute>
                </xsl:element>
            </xsl:when>
            <xsl:when test ="number($yy) &gt;99 or number($yy)&lt; 0">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">yy</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be between 00 and 99</xsl:attribute>
                </xsl:element>
            </xsl:when>
            <xsl:when test="number($mm)&gt;12 or number($mm)&lt;1">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">mm</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be between 01 and 12</xsl:attribute>
                </xsl:element>
            </xsl:when>
            <xsl:when test="number($dd)&gt;31 or number($dd)&lt;1 ">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">dd</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be between 01 and 31</xsl:attribute>
                </xsl:element>
            </xsl:when>
            <xsl:when test="number($HH)&gt;23 or number($HH)&lt;0">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">HH</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be between 00 and 23</xsl:attribute>
                </xsl:element>
            </xsl:when>
            <xsl:when test="number($MM)&gt;59 or number($MM)&lt;0">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">MM</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be between 00 and 59</xsl:attribute>
                </xsl:element>
            </xsl:when>
            <xsl:when test="number($MM)&gt;59 or number($MM)&lt;0">
                <xsl:element name="error">
                    <xsl:attribute name="type">element</xsl:attribute>
                    <xsl:attribute name="name">SS</xsl:attribute>
                    <xsl:attribute name="message">Illegal value. The value should be between 00 and 59</xsl:attribute>
                </xsl:element>
            </xsl:when>
        </xsl:choose>
    </xsl:template>

So this is oinly for messagedate element. I have to make this for all elements like messagedate and it should also give the attribute name as the element name in which I have to use it. I think I have to define a parameter but I am clueless. Can anyone help me? It is quite urgent.

I haven't examined all the logic but if it works as required you just need to modify it to use a param as you said: You can then use the code as before but remove the variable declaration. To call the template use: and use the relevant XPath in the xsl:param select attribute.

I'm not sure what you mean by the last part about attribute name, can you show an example?

for instance

        <xsl:choose>
                <xsl:when test="not(./messagedate)">
                    <xsl:element name="error">
                        <xsl:attribute name="type">element</xsl:attribute>
                        <xsl:attribute name="name">messagedate</xsl:attribute>
                        <xsl:attribute name="message">Element does not exist</xsl:attribute>
                    </xsl:element>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:call-template name ="messagedate"/>
                </xsl:otherwise>
            </xsl:choose>>

here is the attribute name messagedate in my template it is also messagedate. So if I generalize it it should take the element name instead of messagedate. How can I do it?

Well generally you can use the name() function to return a node's name but if it doesn't exist then I don't see how that can work.
For other errors you can use: The other option would be to pass a second parameter:
Note the single quotes around the XPath. Then have: But that's from inside the template, I don't think you can do what you want outside of it unless you use a proprietary extension.

Well actually I have to use XSLT 1.0 specifications. What do you mean by xpath expresions? Can you make it a bit more clear? Thanks for your answer

Your attitude determines your altitude

Well in your first example you had ./messagedate as your XPath to slect the node to be tested but as you want to use this template generally that will change.

joe can you tell me how can I get the element name as a variable in XSLT1.0? I mean for example

<xsl:choose>
   <xsl:when test="not($messageDate)">
    <error type="element" name="{$xpath}" message="Element does not exist" name="error" />
    </xsl:when>
  </xsl:choose>
here for example instead of $xpath I want to get the name of the messagedate tag. How can I do it in XSLT 1.0 with param?


Your attitude determines your altitude

You can't because what is the name of an element that does not exist?

What I am tryin to do is like this:

<xsl:template name="Date204">
        <xsl:param name="Date204"/>
                <xsl:param name="Element"/>
.......
</xsl:template>
<xsl:choose>
                <xsl:when test="not(./messagedate)">
                    <xsl:element name="error">
                        <xsl:attribute name="type">element</xsl:attribute>
                        <xsl:attribute name="name">messagedate</xsl:attribute>
                        <xsl:attribute name="message">Element does not exist</xsl:attribute>
                    </xsl:element>
                </xsl:when>
                <xsl:otherwise>
                    <xsl:call-template name ="Date204">
                        <xsl:with-param name="Date204" select="messagedate"/>
                        <xsl:with-param name ="Element" select ="<elementname>"/>
                    </xsl:call-template>
                </xsl:otherwise>
            </xsl:choose>

That means I want to take this Element parameter als elementtagname.
