| Parameter | Description |
|---|---|
| filename | a string: path to the XML file. |
| name, value | optional pairs: 'AllowDoctype' or 'XMLEngine'. |
| Parameter | Description |
|---|---|
| doc | a Nelson xmlDocument object. |
| parser | an empty placeholder kept for parser compatibility. |
xmlread parses an XML file and returns a Nelson xmlDocument object that can be passed to xmlwrite or xslt.
The object also provides a small DOM-style access layer: getDocumentElement, getElementsByTagName, getTagName, getNodeName, getTextContent, getAttribute, hasAttribute, getLength, and item.
The returned object is not a complete external DOM implementation. The optional second output is currently an empty parser placeholder.
