In Talend Open Studio, I have an XML Node without id: how can I set it?

[spr654]

Hi,

I am using Open Studio 7.1 to compare xml files with JSONB files. 

I have an xml that contains a list of entities.

Each entity has a name.

Each entity has one or several entries.

The entries don't have a name or a value, nothing to identify them.

Each entry can have one or more dataitems

Each entry can have recursive dataGroups

Each entry can have a list of descriptions, containing a number of translations

I need to compare this file with a JSON file that does represent one of my entries.

Issue 1: so far, I got to extract the descriptions with the translations of a given entry (if it does have one), with general information plus the name of the entity.

BUT I don't know how to include a number or id for the entry, so I know that the descriptions belong to entity1, entry1. Does anybody have a solution?

Issue 2: I want to check all the entries, even if they have no lsdlist, But if I put the loop at Entry level, I won't get the ldslist.

Issue 3: I have 4 loops: entry, dataitem, datagroup (recursive...) and lsdlis, and I don't know to to chain them so I know that this entry contains theses dataitems, these datagroups and these lsdlists.  

Any help is welcome.

Here is the root loop I use is: 

ReferenceDataRespMsg/RDEntityList/RDEntity/RDEntry/LsdList/description

Here is the metadata:

Here is the tFileInputXml:

Here is the job (only one entry had lsdList, but I cannot even tell because no way to distinguish entries):

The file I have used is in attachment.

Try the Xpath index-of function.

Something like this:

entryNumber "index-of(../../RDEntry)"

I am not sure of the exact syntax.

You could also look at the position() function.

I found the solution. The ids should be:

For entity: "count(ancestor::RDEntity/preceding-sibling::RDEntity) + 1"

For entry: "count(ancestor::RDEntry/preceding-sibling::RDEntry) + 1"
