Iterate over Direct Children with a Specific Tag

See more XML Examples

Demonstrates how to iterate over direct children having a specific tag.

The input XML, available at http://www.chilkatsoft.com/data/fruit.xml, is this:

<root>
    <fruit color="red">apple</fruit>
    <fruit color="green">pear</fruit>
    <veg color="orange">carrot</veg>
    <meat animal="cow">beef</meat>
    <xyz>
        <fruit color="blue">blueberry</fruit>
        <veg color="green">broccoli</veg>
    </xyz>
    <fruit color="purple">grape</fruit>
    <cheese color="yellow">cheddar</cheese>
</root>

LOCAL lnSuccess

loXml = CreateObject('Chilkat.Xml')

* The sample input XML is available at http://www.chilkatsoft.com/data/fruit.xml
lnSuccess = loXml.LoadXmlFile("fruit.xml")
IF (lnSuccess <> 1) THEN
    ? loXml.LastErrorText
    RELEASE loXml

ENDIF

*  Get the number of direct children having the tag "fruit"
lnNumWithTag = loXml.NumChildrenHavingTag("fruit")

IF (lnNumWithTag > 0) THEN

    FOR i = 0 TO lnNumWithTag - 1
        loChild = loXml.GetNthChildWithTag("fruit",i)
        ? STR(i) + ": " + loChild.Tag + " : " + loChild.Content
        RELEASE loChild
    NEXT
    ? "-----"

    * Do the same as the above loop, but instead of creating
    * a new object instance for each child, call GetNthChildWithTag2 to
    * update the object's reference instead.
    FOR i = 0 TO lnNumWithTag - 1
        * Navigate to the Nth child.  
        lnSuccess = loXml.GetNthChildWithTag2("fruit",i)
        ? STR(i) + ": " + loXml.Tag + " : " + loXml.Content
        * Navigate back up to the parent:
        lnSuccess = loXml.GetParent2()
    NEXT
    ? "-----"
