Hello all,
Currently, the attribute node constructor fails because it can not accept a
node tree pointable and extract the text out of it. So Preston suggested an
alternative to add fn:data during the translation of
DirectAttributeNodeConstructor.
Here is what I am confused about:
I found out that the best place to add this function would be while getting
the expression from enclosed expression. I have a conditional check in,
which tells me if the enclosed expression came in as a part of
DirectAttributeNodeConstructor. Since the enclosed expression is an
abstract syntax tree, I'm not sure how I would go about adding the fn:data
it.
So my best guess is that I am not in the right place to add this function.
Any insight into where exactly can I add this function, before runtime?
This is what the enclosed expression looks like:
"org.apache.vxquery.xmlquery.ast.ExprNode": {
"loc": {
"sourceFileName": "../test_t17.xq",
"lineNumber": 3,
"columnNumber": 15
},
"expressions": [
{
"loc": {
"@reference": "../../../loc"
},
"paths": [
{
"loc": {
"@reference": "../../../../../loc"
},
"path": {
"@class": "org.apache.vxquery.xmlquery.ast.FilterExprNode",
"loc": {
"@reference": "../../../../../../loc"
},
"expr": {
"@class":
"org.apache.vxquery.xmlquery.ast.ParenthesizedExprNode",
"loc": {
"@reference": "../../../../../../../loc"
},
"expr": {
"@class": "org.apache.vxquery.xmlquery.ast.ExprNode",
"loc": {
"sourceFileName": "../test_t17.xq",
"lineNumber": 3,
"columnNumber": 16
},
"expressions": [
{

},

},

"loc": {
"@reference": "../../../../../../../loc"
},
"variable": {
"loc": {
"sourceFileName": "../test_t17.xq",
"lineNumber": 3,
"columnNumber": 17
},
"prefix": "",
"localName": "z"
}
},
"predicates": [

}
}
]
}
]
}
},
"predicates": [

}

}
]
}}
