Thanks Christian for your kind reply

Currently front-end not generating the search combination ( (title = "United States" or isbn = "2345371242192") and author ="Jhon" ) just i am thinking, if i could achieve this way, so that i could ask fron-end person to send this way.

As per implementation, the front-end is not going to send XPATH for any field, I am thinking to generate XPATH on the fly and concatenating it with the search query which will be sent from front-end, is it possible?

The XPATH will be on assumption as per field e.g.(if user select the field author then i have to look on XPATH (*:info/*:author)[1]/*:personname)

For this search ( (title = "United States" or isbn = "2345371242192") and author ="Jhon" ) how should i ask to generate the query from front-end so that combination search can be achieved.

Note: I have to create REST API for this service.

Thanks

Hi Dharmendra,

Thanks for writing to the list.

Could you please give us more details on how this string is generated
by the frontend?

Next, your XPath expression differs in many aspects from the frontend
representation. Some examples:

• It seems that "author" needs to be mapped to:
normalize-space(string-join((*:info/*:author)[1]/*:personname//text())
• "isbn" was mapped to $isbn="*:info/isban" (shouldn’t it be
*:info/*:isbn, and without quotes?)

I assume that it’s not sufficient to map each frontend field to an element name?

Thanks in advance,
Christian
