XML Accumulate Tag Content

See more XML Examples

Demonstrates how to use the AccumulateTagContent method of the XML class.

Imagine the XML document for this test contains the following:

<?xml version="1.0" encoding="utf-8"?>
<abc>
	<zzz>The quick brown fox</zzz>
	<xyz>
	    <zzz>hello world!</zzz>
	</xyz>
	<mmm>
	    <zzz>jumped over the lazy dog.</zzz>
	</mmm>
</abc>

The result of accumulating the content for all "zzz" nodes, but skipping subtrees rooted at "xyz" nodes, is the string "The quick brown fox jumped over the lazy dog." B4X

Dim success As Boolean = False

Dim xml As ChilkatXml
xml.Initialize

success = xml.LoadXmlFile("my_document.xml")
If success <> True Then
    Log(xml.LastErrorText)
    Return
End If


'  Accumulate the textual content within the "zzz" nodes of this
'  XML.  Skip sub-trees rooted at nodes having the tag "xyz".
'  For the given test XML, the resulting accumulated text should be:
'  "The quick brown fox jumped over the lazy dog."
Log(xml.AccumulateTagContent("zzz", "xyz"))
