Form to search XML document

Question

I got a tutorial from W3CSchools on XML and XSL, I have three files (Please see code below) XML - cdcatalog.xml XSL - cdcatalog.xsl HTML - search.htm

What Im trying to do is build a HTML search form to search the XML document, ive change some artist names within the XML file so for example if i did a search for Bob Dylan these three details should be returned, as the search should match bob and dylan in the artist nodes:

<cd>
    <title>Empire Burlesque</title>
    <artist>Bob Dylan</artist>
    <country>USA</country>
    <company>Columbia</company>

    <price>10.90</price>
    <year>1985</year>
  </cd>
  <cd>
    <title>Hide your heart</title>
    <artist>Bonnie Dylan</artist>
    <country>UK</country>

    <company>CBS Records</company>
    <price>9.90</price>
    <year>1988</year>
  </cd>
  <cd>
    <title>Greatest Hits</title>
    <artist>Bob Parton</artist>

    <country>USA</country>
    <company>RCA</company>
    <price>9.90</price>
    <year>1982</year>
  </cd>

Im not sure if this is possible, Any example code would be a great help.

Answer 1

First of all, your HTML is not valid and submitting to an XSL will not result in what you want.
Second - the expression in the XSL

<xsl:for-each select="catalog/cd[artist='Bob Dylan']">

Will match only artist nodes that have exactly Bob Dylan as their value.
If you want partial matches too, you could try using

<xsl:for-each select="catalog/cd[contains(artist, 'Bob') or contains(artist, 'Dylan')]">
