Transformers

Hi all, I am using FME desktop to publish XMLs out. I'm currently using the XML templater and need to edit one of the attributes that is coming through via a feature reader. The sub template expression looks like this (redacted some lines due to data): <data> <dataid>{fme:get-attribute("dataid")}</dataid> </data> There's several other attributes in the XML but I'm not interested in those. Basically what I would like to do is trim the value in that attribute as the attribute has the current format ABCD*00000000001. I only require the numbers in the attribute and only want these written to the final XML output. How do I go about making changes to the XML attributes. I have tried looking at XQueries but not got very far. Many thanks

I'm trying to use the AttributeTrimmer to trim forward slashes from the beginning and end of a string (e.g. - /SomeText/) but I can't find the correct escape character. Thought it was a backslash. Who knows what I need to use to trim /SomeText/ to SomeText? (FME Desktop 2020.1.2.1 - build 20624). Thanks, Aaron

Can someone please suggest something to improve the performance?

FYI - I'm fairly new to FME and would like to start using it much more in our workflows, any help is appreciated. I'm converting a model from Revit to FBX. Where I am transforming the coordinates to a local ENU CS prior to export. I have created a transformation matrix using the Python Caller, where I intend to use the generated coefficients in a 3DAffiner. Manually adding the coefficients into the 3DAffiner works well: Here I simply printed the values of a1-c4 with the first run of the workspace, then pasted these values into the 3DAffiner to produce the FBX file. What I want to do is pass the a1-c4 attribute values from the PythonCaller into the 3DAffiner, as below: Although I recieve an error when doing this: 3DAffiner_ecef_local_origin (TeeFactory): 3DAffiner_ecef_local_origin: Unable to convert @Affine parameter A value `<Null>' to a floating point value As you can tell, the issue is because the feature to be transformed by the 3DAffiner doesn't have these attributes. So my questi

I ran into some quirkyness with lined custom transformers today\\ Normally, when one has a workspace with a linked custom transformer, and you change the stuff between the input and output ports of that transformer, the next time you run this workspace uses the new functionality. That is when you save the transformer and don't make a new version. The parameters of the linked transformer are not changed. Obviously that goes for the published parameters, you set in the workspace through dropdown menu's etc. on the linked custom transformer, but it also seems to go for the private parameters of the linked transformer. It looks like they are stored in the workspace as wel in some sort of way. When you have changed these during the rework on the Linked transformer, still the old private parameters seem to be used when running the workspace! In my case the private parameters were python-scripted parameters in the linked transformer. I changed the python-scripts. When running the workspace wi

In the new, fantastic, InlineQuerier (2023 beta), a geometry column can be selected. Is there a way to call directly the geometry of the feature without geometryextractor? On the same topic, is there a way to define the ouptput geometry without using an ST_asText followed by a GeometryReplacer?

On the VM there is a C drive with 80 GB on the C drive and 80 GB on the D drive. Wanting to ensure we don't run into any issues.

I have attached an excel spreedsheet. I would like to merge and convert the table in sheet 1 ("Year_2035') and sheet 2 ('Year_2050') into a table structure like that one in 'RequiredFormat' sheet. I have never transformed such a complex data structure in FME before. Can anyone kindly help with good suggestions?

Hello everyone, I am trying to round the x, y and z components of Pointclouds to a precision of 3. I have tried the coordinaterounder but as is already stated in the Coordinaterounder documentation (http://docs.safe.com/fme/html/FME_Desktop_Documentation/FME_Transformers/Transformers/coordinaterounder.htm) the behaviour of this transformer can be erratic. For some points I get far more then 3 decimal places, while for others it is rounded to an integer. I have also tried the Pointcloudexpressionevaluator as in this solution (https://community.safe.com/s/question/0D54Q00009HJ87MSAT/rounding-ifmepointcloud-xyz-components-with-pythoncaller) but this also does not seem to work for my data. Is there another option I could try or is there maybe something I might be missing from the previous solution? Thank you in advance!

Hi, Does anyone know if there is also an issue for writing textures to geometry for OBJ and FBX format writer in FME v2022.2? It seems the same issue for Sketchup writer has been fixed. During test the issue for OBJ and FBX format seem to be present.

I have simple script with adding color palette to raster ASC after cell value replacer . In ouput GeoTIFF i received too many palette colors represented with black color. | In attachment i send script. It's possible to have only 3 selected colors without black numbers?

Hello Sir / Madam, I have a gdb file that have several layers. I am just wondering how can I extract all attributes from the layers? I tried "Schema" reader and list exploder to explode the data. However, I only able to get one table attributes. May I ask how can I extract all attributes from all layers? I have attached a sample data in here. Hope someone can give me a hand. Thank you! Thank you in advance.

Hello Sir/ Madam, So I have a CityGML file, which is based on XML. In each of the 3D model, I would like to extract the attribute name and values. Basically, what I want is that those with gen:string attribute name and bldg are the values where I would like to retreive. Here is a part of the file <gen:stringAttribute name="BuildingStructureID"> <gen:value>15169952</gen:value> </gen:stringAttribute> <gen:stringAttribute name="BuildingCSUID"> <gen:value>3917120211T20050430</gen:value> </gen:stringAttribute> <gen:stringAttribute name="BuildingID"> <gen:value>1108233601</gen:value> </gen:stringAttribute> <gen:stringAttribute name="ModelIdentityNumber"> <gen:value>B391712021101062A0</gen:value> </gen:stringAttribute> <gen:stringAttribute name="UUID"> <gen:value>22fe4b82-05e8-44ec-91cc-3408862e240a</gen:value> </gen:stringAttribute> <gen:stringAttribute name="BuildingStructureType"> <gen:value>T</gen:value> </gen:stringAttribute> <gen:stringAttribute name="BuildingNameEN"> <gen:value> </gen:

This would be simple to do in Excel, but I can't figure it out on FME. The problem is I need to transpose or pivot rows to colums, as in example (I have formatted and calculated the totals to first box): I have tried with AttributePivoter and AttributeCreator/Aggregator, but it doesn't work. Any help would be appreciated, I've tried to google, but with no luck. I have also tried to pivot the unprocessed data and calculate it there.

Hi, Yesterday I came across the situation where I wanted to split a text file into several portions. For 'new lines', the file contained both single Line Feeds (i.e. LF or \\n) as Carriage Return - Line Feed (i.e. CRLF or \\r\\n) combinations. Thus both the Unix End Of Line (EOL) methodology and the Windows EOL methodology were present. I used the StringSearcher to match relevant parts of the text file, and then wanted to use (concurrent) all_matches{}.startIndex to fetch the relevant portions of the file. However, I found out that when I then use the found startIndex in e.g. the SubstringExtractor, it doesn't doesn't return the same (starting) characters as found in the match. Digging a bit deeper, it seems that the StringSearcher all_matches{}.startIndex seems to skip counting CR (\\r). I'm guessing it identifies CRLF (\\r\\n) as an individual character c.q. index? See the screenshot below for a demo workspace illustrating this issue. Also, I found that the equivalent @FindRegularExp

How can I maintain my Z values in my featuresclass using surface draper while replacing the vertices that lack a Z value using the surface provided?

I am trying to create a workspace that writes AGOL features to AutoCAD Map format with object data attributes. Not having much success. :-(

Hi, since my last update of the workbench (2022.2.0.0 (20221103 - Build 22765 - WIN64)) the parameter editor of the attribute manager wont allow me anymore to edit directly in the pane next to my main window. I have to open a unneccessary pop-up window to continue editing. Other transformers (like the feature joiner) do not show this behavior (see screenshot). Any ideas how to enable direct editing again? All the best, Merlin

Hi, I would like to force FME into treating my numbers as double before sending it to the feature writer transfomer. This allows me to make use of the automatic user attribute functionality, otherwise I would to manually define each attribute, which is cumbersome. For example: I have calculated the difference between reported and measured plot sizes. The result is stored in a colum as number, but it seems that FME interprets the number as string ... no matter if I use the @Evaluate() function or any other math function ... also string replacer cant change that. The result is always the same: i have to change the format in the feature writer, which I would like to avoid. main_plot_diff is left aligned, showing that FME interprets the data as string. string replacer is powerless... ... and the feature writer also interprets the data as string

Hi there, I have an excel file with approximately 4500 rows of data, which I am converting to HTML. I can write perfectly, but I also want to write a PDF from this information. Reading through previous questions I can see you can't write straight from the HTML Report Generator, so I have added a Table Adder transformer before this, but it creates a completely blank PDF. I have used a combination of PDFStyler and PDFPageFormatter but still keep getting blank PDFs. Any suggestions? Thanks, Katie

I have polylines that have Z coordinates on each vertex. The polylines represent water pipes and are below the ground surface ~1 meter. I have a LAS of the ground surface which can be converted to a raster to create a surface. The situation can occur where the polylines get above the ground surface in between the vertices due to variation in terrain and lack of vertices with X, Y, Z values in the polylines. How can I identify those locations and add an extra vertex so the polylines will stay below the ground surface?

i have dragged and dropped a LL27 shapefile on to Fme workbench 2020.2. Then I add a writer. Set the output dimension as 2D and coord system as TX-S. Running this is giving the error as above. The same workflow runs without errors in FME workbench 2017.1 In fact I do not have to set any dimension in 2017.1 The simple coordinate conversion from LL27 to TX-S runs normally. Wondering what I need to tweak out here in 2020.2 to get the same result

Hello:) i'm trying to overly 2 rasters : 1- orginal raster (orthophoto) 2- bounding box of the original raster as a boundig box rectangle +100 offset i'm using rasterMosaicker , but the result only shows the rectangle and not the orthophoto i tried sorting - didn't help see the attached workflow and parameters: the result that i'm getting in the inspector which is the correct one - black rectangle + orthophoto: result that i;m getting after the mosaicker (only the black rectangle): why i'm getting different result from the inspector ? the parameters for the mosaicker are: thanks

Hi, It seems to me that there might be an issue when I'm trying to fetch a parameter value of a Custom Transformer, from a PythonCaller inside that Custom Transformer. If I do so, I obtain an error. When I try to do so in the main workspace, or when I add the name of the CT in the parameterfetcher, I don't get an error, and it works. See below screenshot and the attached demo workspace for an example. This seems like a bug to me, but it would be nice if the community can have a look alongside me. Kind regards, Thijs Ps. as a sidenote, I came across this Community Question in which the best practice for accessing parameter values inside a PythonCaller is discussed. In it, it is mentioned that best practice is to use param = fme.macroValues[‘parameterName’] in favour of param = FME_MacroValues[‘parameterName’] Additionally, it is mentioned that DaveatSafe created a problem report 4 years ago to make sure that this best practice is also honoured in the script editor for the PythonCaller/C

Is it possible in the MongoDB reader to have a JSON Query similar to {"_id" : { "gte" : { "$date" : "@DateTimeFormat(@DateTimeAdd(@DateTimeNow(local),-P7D),%Y-%m-%dT%H:%M:00.000)Z" } } } I have tried putting the entirety into a User Parameter, but the date section does not get calculated before being sent to MongoDB, leading to a warning being of the following. MONGODB3 reader: Feature Type Parametr 'mongodb_query_document' has invalid value '{"_id" : { "gte" : { "$date" : "@DateTimeFormat(@DateTimeAdd(@DateTimeNow(local)' for feature type
