About the pub.xml:loadXMLNode Service
You use the pub.xml:loadXMLNode service to retrieve and parse an XML or HTML document from the Internet. This service does the following:
First, it submits a HTTP or HTTPS request for a specified XML or HTML document.
Then, it parses the returned document using the legacy XML parser.
The output from pub.xml:loadXMLNode is an XML node that can be used with any service that takes a document or a node as input.
Note:
If you want to fetch a document from a local file system, do not use pub.xml:loadXMLNode. Instead, use the pub.file:getFile service. For more information, see the webMethods Integration Server Built-In Services Reference.
