I’m trying to extract data from a JS variable from page that has a structure like this:
<!DOCTYPE html><html><head>
...
</head><body><divid="main">
...
</div><script>varconfig={"test": "one"};varPageData={"someVariable": [{// data}];};</script><script>// some other script</script></body></html>
My goal is to monitor changes to the contents of PageData.someVariable (actually even deeper than that, as is quite a complex object).
So far, I used the Extract text feature with the following regex: /.*?var\s+PageData\s*=\s*({[\s\S]*?});/i
This successfully captures the object assigned to PageData. However, I’m unable to use the CSS/JSONPath/JQ/XPath Filters box to drill into the data (e.g., $.someVariable)—I’m guessing that’s because the JSONPath filter is run before the extract step?
Has anyone successfully extracted and navigated JS variables like this?
I’d love any help or workarounds—do I need to reformat the extract or is there a better way to approach this?
I guess I could "simply" use the "Extract text" functionality on the actual object variable I'm after (e.g. /\{[^{}]*object_property[^{}]*\}/), but that still doesn't allow me to parse it as json...
