## The Concordance File

The **concordance** is an RDB to XML Crosswalk that maps all xpaths onto a specified set of variables. It is located in the **irs990efile** package.

# Diagnostics 

## Missing or Extra XPATHS 

Check for xpaths that were used in the tables but do not exist in the Concordance file.  

```{r}
c.table <- dplyr::filter( concordance, rdb_table == table.name ) 
xpath.concordance <- c.table$xpath
setdiff( all.xpaths, xpath.concordance )
```

Capture to update the Concordance file. 

```{r}
these <- setdiff( all.xpaths, xpath.concordance )
cat( these, sep="\n", file=paste0( folder.name, "/MISSING-XPATHS.txt" ) )
```



## Failes URLs 

Check the status of failed URLs. 

```{r}
if( length(fail.log) > 0 )
{ 
  sapply( fail.log, get_message ) %>% 
  table() %>% 
  pander() 
} else {
  print("ALL URLs ARE VALID")

# XML Table Structure


```{r, eval=F, echo=F}

### Get nodesets from test data: 

if( is.null(table.headers) )
{ table.headers <- find_table_headers( table.name ) }

all.headers <- paste0( table.headers, collapse="|" )

node.list <- list()

for( i in 1:length( test.urls ) )
{
  url <- test.urls[i]
  doc <- NULL
  try( doc <- xml2::read_xml( file(url) ), silent=T )
  if( is.null(doc) ) next
  xml2::xml_ns_strip( doc )
  node.list[[i]] <- xml2::xml_find_all( doc, all.headers, flatten=TRUE )
  # node.list[[i]] <- XML::getNodeSet( doc, all.groups )
}

### Getting xpaths from nodelists: 

get_unique_xpaths <- function(x)
{
  xpz <- 
    x %>% 
    xml_parent() %>% 
    xmltools::xml_get_paths() %>%
    unlist() %>% 
    unique()
  return(xpz)
}

all.xpaths <- 
  lapply( node.list, get_unique_xpaths ) %>% 
  unlist() %>% 
  unique()
```


## Create Network Edgelists


The **create_edgelist()** functions v1 and v2 are in R/utils.R. 

V1 retains the root nodes Return and ReturnData. 

V2 drops the root nodes and uses form versions "990" and "990EZ" as the root to visualize the sets of tables separately. 

```{r, eval=F, echo=F}
all.xpaths <- 
  readLines( paste0( folder.name,"/XPATH-LOG.txt" ) ) %>% 
  unique() %>% 
  sort()
```

```{r}
# KEEP ROOT NOTES Return & ReturnData
el <- create_edgelist_v1( all.xpaths )
```

<br>
<hr>
<br>

Edgelist format: 

```{r, echo=F}
el.demo <- 
structure(list(V1 = c("Return", "ReturnData", "IRS990", "Form990PartVIISectionAGrp", 
"Form990PartVIISectionAGrp", "Form990PartVIISectionAGrp", "Form990PartVIISectionAGrp", 
"Form990PartVIISectionAGrp", "Form990PartVIISectionAGrp", "Form990PartVIISectionAGrp"

"PersonNm", "TitleTxt", "AverageHoursPerWeekRt", "IndividualTrusteeOrDirectorInd", 
"OfficerInd", "ReportableCompFromOrgAmt", "ReportableCompFromRltdOrgAmt"

# XPATH Summary

## Unique Xpaths for this RDB Table

```{r}
t.xpaths <- 
  concordance %>%
  filter( rdb_table == table.name ) %>% 
  select( xpath ) %>% 
  unique() %>% 
  arrange( xpath ) %>% 
  mutate( id=row_number() ) 

t.xpaths %>% 
  kable( align="l" )
```


```{r, echo=F, eval=F}
## Compare xpath Levels

xpaths <- as.character( t.xpaths$xpath )
nodes <- strsplit( xpaths, "/" )
xpath.levels <- sapply( nodes, length )
max.lev <- max( xpath.levels )
nodes <- lapply( nodes, function(x){ c(x, rep("",max.lev-length(x) ) ) } )

# compare xpath levels
xpath.levels <- data.frame( do.call( cbind, nodes ), stringsAsFactors=F )
xpath.levels[ , 1:10 ] 
```





## Grouping Variables

Identify all unique groups used in xpaths. 

```{r}
if( is.null(table.headers) )
{ find_table_headers( table.name ) } else
table.headers
```



Groups can then be used to extract the 1:M RDB tables: 

```{r, paged.print=FALSE}
if( is.null(table.headers) )
{ table.headers <- find_table_headers( table.name ) }
demo.url <- "https://nccs-efile.s3.us-east-1.amazonaws.com/xml/201913079349300206_public.xml"
doc <- xml2::read_xml( demo.url )
xml2::xml_ns_strip( doc )
df.demo <- get_table_v2( doc, table.name, table.headers )
df.demo 
```





## Standardize Variable Names

Mapping of xml variable names to concordance variable names: 

```{r}
get_var_map( table.name=table.name )
```

A table with proper names: 

```{r paged.print=FALSE}
v.map <- get_var_map( table.name=table.name )

if( ! is.null(df.demo) )
{re_name( df.demo, v.map ) %>% as.data.frame()}
```
