XML Reader

Reads a well formed XML document. An XPath query can be specified to read only a portion of the file. In this case the output will be the nodes in the document that match the XPath query.

Options

Selected File

The XML document to read. It can be a local file on disk or a URL.

Use XPath Filter

If checked, only the nodes of the document, which match den XPath query, will be read.

XPath Query

Only nodes of the document, which match this XPath query, will be read. Each matching node is read in a single data cell.

Note, that XPath requires to explicitly denote namespaces. E.g. to read only the body of a XHTML document you can use the XPath query:
/dns:html/dns:body
where dns is the prefix of the namespace defined in the Namespaces table.

A limited XPath syntax is supported. Only absolute paths to nodes can be defined. Among the XPath operators the |-Operator is supported. It can be used to read e.g. the head and the body of an XHTML document in single cells:
/dns:html/dns:head | /dns:html/dns:body

Namespaces

The prefixes and the namespaces used in the XPath query. For the example in XPath Query following namespace must be defined:
Prefix: pre
Namespace: http://www.w3.org/1999/xhtml

Incorporate namespace of the root element.

This option is useful when you do not have the default namespace of your document at hand.

If checked, the namespace of the root element is added to the Namespaces table during runtime. Please define a prefix for this namespace in Prefix of root's namespace.

For the example of XHTML documents the namespace of the root element is http://www.w3.org/1999/xhtml so that with the root's prefix of dns you can leave the Namespaces table empty.
