Comparing different approaches to parse large XML messages.
[](http://thlorenz.github.io/exmala/client/)
## Streaming
When not buffering and writing to multiple parsers at once we risk running out of memory since all these parsers keep
a stack and other stateful things around that cost us memory.
Depending on the parser lib we use that happens at a specific level of concurrency.
#### htmlparser2
```
settings:
{ parser: 'htmlparser',
streaming: true,
concurrency: 1000,
number: 2000,
gc: false,
file: '/Users/thlorenz/dev/js/exmala/data/ibm-request.soap.xml',
resultsFile: '/Users/thlorenz/dev/js/exmala/results/streaming-htmlparser-c1000-n2000_ibm-request.soap.xml.json' } }
FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory
```
#### xml2js
```
{ settings:
{ parser: 'xml2js',
streaming: true,
concurrency: 500,
number: 2000,
gc: false,
file: '/Users/thlorenz/dev/js/exmala/data/ibm-request.soap.xml',
resultsFile: '/Users/thlorenz/dev/js/exmala/results/streaming-xml2js-c500-n2000_ibm-request.soap.xml.json' } }
FATAL ERROR: CALL_AND_RETRY_2 Allocation failed - process out of memory
