Question

I just got a website assignment and it server apparently does not support databases. So I was thinking, in a traditional XML DTD…we have data like this:

<book category="CHILDREN">
    <title>Harry Potter</title>
    <author>J K. Rowling</author>
    <year>2005</year>
    <price>29.99</price>
</book>

Using Text Boxes and maybe by linking using XSLT or something else, can I add/insert more data into my existing XML sheet??

Also, can I perform validation such as no duplicate titles??

I’m kind of new to this and some help would be appreciated.

If this is about adding “rows” to your book “record”, then you can do this

<xsl:template match="/">
  <xsl:apply-templates/>
</xsl:template>

<!-- match book explicitly ... -->
<xsl:template match="book">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>

    <!-- and add one "row" to the books content -->
    <one-more-row>value</one-more-row>
  </xsl:copy>
</xsl:template>

<!-- Just copy all the other elements/attributes (including book contents) -->
<xsl:template match="@*|node()">
  <xsl:copy>
    <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
</xsl:template>
