XPath

To open the XPath preferences panel go to Window > Preferences > Author > XML > XSLT/FO/XQuery > XPath.

Oxygen XML Author plugin allows you to customize the following options:

Unescape XPath expression - the entities of an XPath expressions that you type in the XPath toolbar are unescaped. For example the expression
```
//varlistentry[starts-with(@os,'&#x73;')]
```
is equivalent with:
```
//varlistentry[starts-with(@os,'s')]
```
No namespace - if you enable this option, Oxygen XML Author plugin considers unprefixed element names of the XPath 2.0 expressions evaluated in the XPath toolbar as belonging to no namespace.
Use the default namespace from the root element - if you enable this option, Oxygen XML Author plugin considers unprefixed element names of the XPath expressions evaluated in the XPath toolbar as belonging to the default namespace declared on the root element of the XML document you are querying.
Use the namespace of the root - if you enable this option, Oxygen XML Author plugin considers unprefixed element names of the XPath expressions evaluated in the XPath toolbar as belonging to the same namespace as the root element of the XML document you are querying.
This namespace - in this field you can enter the namespace of the unprefixed elements used in the XPath toolbar.
Default prefix-namespace mappings - in this field you can associate prefixes with namespaces. Use these mappings when you want to define them globally, not for each document.
