[oXygen-user] curiosity sake

14 Nov 2003

      ...
FIRST:
In this problem, I just need the last four digits of the ISBN. But the
catch is that the ISBN length is not constant, but is always greater than
George,

Just for curiosity sake,

In problem #2, we know that there are digits at the end to be removed, but 
what if digits and alphabets are mixed? Ex:

XML FILE
<INFO>some book 19 some discription</INFO>
<INFO>another book 2000 some description again</INFO>
<INFO>the last book 90 text</INFO>

Now, we need just the text before the number. i.e. "some book" or "another 
book".

Thanks

Hi Aga,

...
XML FILE
<ISBN>23fds783222s</ISBN>
<ISBN>f2h123as</ISBN>
<ISBN>2hgfhhgf3432h123asssz</ISBN>
If you want the last for characters from a string you can use something
like:
<xsl:variable name="value" select="."/>
<xsl:value-of select="substring($value, string-length($value)-3)"/>
If you want to remove eventual characters before getting the last 4
characters you can select the value as below:
<xsl:variable name="value" select="translate(., 'abcde....', '')"/>
...
SECOND:
I have no idea how to go about this one. I just have to select the text
before the number. Do you have any idea?
XML FILE
<INFO>hotmail 1990</INFO>
<INFO>some text here 2000</INFO>
<INFO>some more text gere 9092</INFO>
If you know you have a 4 digit number then you can use substring to get it:
<xsl:value-of select="substring($value, 1, string-length($value)-4)"/>

If you know that the text does not contain numbers you can use translate to
remove the digits:
<xsl:value-of select="translate($value, '0123456789', '')"/>

otherwise you can use a template to remove digits from the end:

    <xsl:template name="selectBeforeNumber">
      <xsl:param name="value" select="''"/>
      <xsl:variable name="c" select="substring($value,
string-length($value))"/>
      <xsl:choose>
        <xsl:when test="$c='0' or $c='1' or $c='2' or $c='3' or $c='4' or
$c='5' or $c='6' or $c='7' or $c='8' or $c='9'">
          <xsl:call-template name="selectBeforeNumber">
            <xsl:with-param name="value" select="substring($value, 1,
string-length($value)-1)"/>
          </xsl:call-template>
        </xsl:when>
        <xsl:otherwise>
          <xsl:value-of select="$value"/>
        </xsl:otherwise>
      </xsl:choose>
    </xsl:template>

and call it like below if the current selection is an INFO node:

<xsl:call-template name="selectBeforeNumber">
  <xsl:with-param name="value" select="."/>
</xsl:call-template>

 George
