@XMLHASXPATH[["filename",],xpath] : Returns 1 if the xpath exists in the XML file, or 0 if it doesn't.
If you do not specify a filename, @XMLHASXPATH will use the file previously opened by @XMLOPEN.
@XMLHASXPATH may be used to check if an xpath exists before setting it via @XMLXPATH.
The XML parser in TCC implements a subset of the XML XPath specification, allowing you to point to specific elements in the XML documents. The xpath is a series of one or more element accessors separated by '/'. The path can be absolute (starting with '/') or relative to the current XPath location.
The following are possible values for an element accessor:
'name' |
A particular element name |
name[i] |
The i-th subelement of the current element with the given name |
[i] |
The i-th subelement of the current element |
[last()] |
The last subelement of the current element |
[last()-i] |
The subelement located at the last location minus i in the current element |
name[@attrname="attrvalue"] |
The subelement containing a particular value for a given attribute (supports single AND double quotes) |
.. |
The parent of the current element |
