XPath examples
Consider the following XML:
<root>
text1
<a att="100.1">A text 1</a>
<a>A text 2</a>
<b att="300.0">
<a att="400.4"/>
</b>
This is an interesting text string
</root>
Suppose that the following properties are set in the XML codec section of the IAF configuration file:
<property name="XMLField" value="Test"/>
<property name="XPath:Test->MyXPathResult.last-a" value="*/a[last()]"/>
<property name="XPath:Test->MyXPathResult.first-att" value="//@att"/>
<property name="XPath:Test->MyXPathResult.first-a-text" value="/root/a[1]/text()"/>
<property name="XPath:Test->MyXPathResult.att>200" value="//@att>200"/>
<property name="XPath:Test->MyXPathResult.att-count" value="count(//@att)"/>
<property name="XPath:Test->MyXPathResult.text-contains"
value="contains(/cdata-root/text()[last()], "interesting")"/>
With these property values, the XML fragment maps to the following normalized event fields:
"MyXPathResult.last-a" = "A text 2"
"MyXPathResult.first-att" = "100.1"
"MyXPathResult.first-a-text" = "A text 1"
"MyXPathResult.att>200" = "true"
"MyXPathResult.att-count" = "3"
"MyXPathResult.text-contains" = "true"
