title: "HCL AppScan on Cloud SAST"
toc_hide: true
---
HCL Appscan on Cloud can export the results in PDF, XML and CSV formats but this parser only supports the import of XML generated from HCL Appscan on Cloud for SAST scans.

### Sample Scan Data
Sample HCL AppScan on Cloud SAST scans can be found [here](https://github.com/DefectDojo/django-DefectDojo/tree/master/unittests/scans/hcl_asoc_sast).

Instead of putting the whole function after this point inside an if block when report is not None, just bail if report is None.

I was keeping the overall style of the parser similar to the existing hcl_appscan (for DAST) parser for consistency. I can refactor if this is a dealbreaker.

for finding in report:
title = ""
description = ""
for item in finding:
match item.tag:
case "severity":
output = self.xmltreehelper(item)
severity = "Info" if output is None else output.strip(" ").capitalize()
case "cwe":
cwe = int(self.xmltreehelper(item))
case "issue-type":
title = self.xmltreehelper(item).strip()
description = description + "**Issue-Type:** " + title + "\n"
case "issue-type-name":
title = self.xmltreehelper(item).strip()
description = description + "**Issue-Type-Name:** " + title + "\n"
case "source-file":
location = self.xmltreehelper(item).strip()
description = description + "**Location:** " + location + "\n"
case "line":
line = int(self.xmltreehelper(item).strip())
description = description + "***Line:" + str(line) + "\n"
