I have an already existing XML target in informatica power centre, but the file that was used to import this definition is missing.
I need to add one more tag to this target definition. I am aware of the “synchronise XML definition” option.
How would i approach this?

I wanted to get the flat files as source without any file structure specified using IICS(Informatica Intelligent cloud services). Flat files names can be anything, and structure also will change any. And also need to create table dynamically based on flat file and insert into table.
There's a number of options here. You can use a fully parameterized mapping niside a taskflow that will start on file listener, prepare the parameters and statements to be executed as part of the pre-SQL statement on your Target.
Inside the mapping you define Source and Target as parameterized - and that's briefly it!
I need to read a text file (JSON format) and load it into a database table in Informatica Developer. For only one text file and one database table, that is easy.
But now I have N different text files, hence N different database tables and their corresponding data processor transformations. The transformation logic inside the mappings is the same. Besides creating N sets of mappings and workflows for each set of text files, is it possible to create just one generalized mapping and workflow to cater for all text files? I would appreciate it if any one of you could give me a general direction for me to explore further.
I have a Dataprep flow configured. The Dataset is a GCS folder (all files from it). Target is BigQuery table.
Since data is coming from multiple files, I want to have filename as of the columns in the resulting data.
Is that possible?
UPDATE: There's now a source metadata reference called $filepath—which, as you would expect, stores the local path to the file in Cloud Storage (starting at the top-level bucket). You can use this in formulas or add it to a new formula column and then do anything you want in additional recipe steps. (If your data source sample was created before this feature, you'll need to generate a new sample in order to see it in the interface)

Original Answer
This is not currently possible out of the box. IF you're manually merging datasets with UNION, you could first process them to add a column with the source so that it's then present in the combined output.
If you're bulk-ingesting files, that doesn't help—but there is an open feature request open that you can comment on and/or follow for updates:

Iam new to Informatica,I have to add two new fields(AREA,AMT) to an already existing SQL query in Informatica. After this should I manually add the source qualifier port with these two fields?
What I did was:
1) Changed the query in SQL qualifier in Mapping designer- added the two new fields, saved the mapping
2) Refreshed the workflow in Workflow designer
3) Monitored the result in Workflow Monitor which was successful.
Now, the resulting text file has the new field values but no column header names. Hence the column header values are shifted resulting in column name and value misalignment.
Any help on this is appreciated.
Thanks!
YES you should manually add the two ports to the Source Qualifier. The number of fields selected in the SQL query should match the number of ports in the Source qualifier which are linked to the next transformation.
Interestingly Informatica maps the fields from the SQL query to the Source qualifier output links instead of Source Qualifier ports. So the first column in the SQL query gets mapped to the first link, second column to the second link and so on.
For your header issue, you should let us know how you are generating the headers for the output file. If you are using "Use header command output" option in the target file session properties for generating headerthen you have edit the command to create header for there two new ports as well.
I want to copy the data into one excel file, while the mapping has been running in informatica.
I used Informatica last year, now am on SSIS. If I remember correctly, you can setup a separate connection for Excel target destination. There after you pretty much drag all fields from your source to the target destination (in this case Excel).
As usual develop a mapping with source and target.
But make target as Flat File while creating target.
Then run the mapping u will get
