Everybody! This is important. In a few days, these forums will be moving over to using the totally sweet Discourse platform. To ensure this migration happens smoothly with no loss of content, these forums are currently in a read-only mode. I do apologize for the inconvenience.

There is never a good time to turn the forums off for an extended period of time, but I promise the new forums will be a billion times better. I'm pretty sure of it.

See you all on the other side in a few days, and if you have any (non-technical) questions, please e-mail me at kirupa@kirupa.com. For technical questions, try to find a tutorial that corresponds to what you are looking for and post in the comments section of that page.

    XML Keyword Search Problems

    I am making a program to download files from a server with a simple interface, but I am having a problem with the search box. My problem is that the search box only returns a value if the XML node value is exactly the same value that was searched for. If I type in "Internet Explorer 7" I get the result, but If I were to type in "internet explorer 7" or just "internet explorer" nothing comes back.

    I want my users to get search results even if they don't know the exact name they are looking for.

    Any thoughts?


    Here is what I have so far.

    Partial XML
    <program category="Internet">
    <name>Internet Explorer 7</name>
    <program category="Internet">
    <name>Internet Explorer 6</name>

    function searchParseData(dataInput:XML):void {
    var searchString:String = txtSearch.text
    var nameList:XMLList = dataInput.program.(name == searchString);
    universalNameList = nameList;
    //Add Items to Name ComboBox
    for (var i:int = 0; i < nameList.length(); i++)
    cboName.addItem({label:nameList.name.text()[i], data:nameList.name.text()[i]});

    Short of creating an index, why not first make case irrelivent by converting both the search and xml string to lowercase (locally only for the search) and then use if( string.indexOf(search phrase) > 0 ) as you loop through your xml data to determine whether or not the search phrase features anywhere within the string. This would be the simplest method, though of course if you are versed in them, using regular expressions might prove to be faster.
