Is it possible to invert the action of a clip with SVG? I'd like to show the path between the two circles rather than inside the circles:
<svg width="50%" height="50%" viewbox="0 0 985 740" xmlns="http://www.w3.org/2000/svg">
<g>
<clipPath id="re8-clip" clip-rule="nonzero">
<rect id="sa11" x="763.0" y="176.5" width="70.0" height="25.0" rx="50" ry="50" fill="ForestGreen"/>
<rect id="sa12" x="516.0" y="127.5" width="70.0" height="25.0" rx="50" ry="50" fill="ForestGreen"/>
</clipPath>
<rect id="sa11" x="763.0" y="176.5" width="70.0" height="25.0" rx="50" ry="50" fill="ForestGreen"/>
<rect id="sa12" x="516.0" y="127.5" width="70.0" height="25.0" rx="50" ry="50" fill="ForestGreen"/>
</g>
<path stroke="Black" stroke-width="1.5" fill="none" d="M 798.0 189.0 551.0 140.0" clip-path="url(#re8-clip)"/>
</svg>
Following the link in Duopixel's comment, the problem can be solved using a mask:
<svg width="50%" height="50%" viewbox="0 0 985 740" xmlns:xlink="http://www.w3.org/1999/xlink" xmlns="http://www.w3.org/2000/svg">
<defs>
<rect id="sa11" x="763.0" y="176.5" width="70.0" height="25.0" rx="50" ry="50" />
<rect id="sa12" x="516.0" y="127.5" width="70.0" height="25.0" rx="50" ry="50" />
</defs>
<mask id="re8-clip">
<rect id="bg" x="0" y="0" width="100%" height="100%" fill="white"/>
<use xlink:href="#sa11" fill="Black" />
<use xlink:href="#sa12" fill="Black" />
</mask>
<use xlink:href="#sa11" fill="ForestGreen" />
<use xlink:href="#sa12" fill="ForestGreen" />
<path stroke="Black" stroke-width="1.5" fill="none" d="M 798.0 189.0 551.0 140.0" mask="url(#re8-clip)"/>
</svg>
As a minor aside, does anybody know if it is possible for a mask to default to white, so the 'bg' rectangle is not necessary?

I'm trying to use different SVG elements with a pattern as a fill, but the pattern doesn't get repeated for every element. I'm not sure if there's the possibility to repeat the pattern, but right now it looks as if there's a pattern and three circles create a mask over the pattern. What I want to achieve is the three circles clearly looking differently because each pattern resets for each circle and then it doesn't look 'cut out'.
I suppose a last-resort solution would be to create multiple patterns with different names for every element I use, then it'll work, but I'm hoping there's a less cumbersome way.
I tried:
Wrapping each element in a different SVG container
Appending ids to the elements and then in css target every id separately with the fill being the url
I made a codesandbox which shows my problem:
https://codesandbox.io/s/busy-ives-hv3rr?file=/index.html
The solution #herrstrietzel posted is one way to go.
Another solution is to create variants of your original pattern, but with a different origin. You specify the origin using the x and y attributes.
<svg id="patternId" width="100%" height="100%">
<defs>
<pattern id="a" patternUnits="userSpaceOnUse" width="65" height="65" patternTransform="scale(2) rotate(0)">

Another alternative is to switch to objectBoundingBox units. So that the pattern is relative the the object it is applied to.

Applying transforms like transform="translate(50 50)" (instead of fixed x/y positioning would do the trick.

Worth noting: duplicating patterns for slightly modified usage is pretty straight forward, since the <pattern> element supports referencing/reusing previously defined patterns via href attribute (similar to <use>):
<pattern id="pattern-1" href="#pattern-0" x="80" y="80" patternTransform="scale(2) rotate(45)" />
Would result in a rotated pattern sharing all properties of the initially defined pattern.
I am trying to make mirrored pattern, but when I add displacement filter, it seems it only works on first and fourth quandrant. Am I overlooking some beginner mistake or is this behavior expected?

In your filter I've added xChannelSelector="R" for the feDisplacementMap. I'm using R for red since your shapes are red.

Also I would have applied the filter to the <rect> inside <symbol> instead of applying it to the group.
You're just missing an xChannelSelector or yChannelSelector - one of which is required.
(Update - as you mention in the comment, when you leave this out, it defaults to using the alpha channel in both X and Y - so it will shift everything up and down the top/left bottom/right diagonal axis - so solid color diagonal lines with this orientation will only show distortions at their starting and finishing edges).
If you're not going to process the feTurbulence in some way after you generate it, then any one of the channels (RGBA) works as a displacement source - since Perlin noise is equally noisy in all four channels.
(You don't need to use the R channel because your shapes are red - that's backwards - the channel selector applies to your noise input, not your the shape you want to apply it to.)

I'm looking to mask a portion of a straight line in SVG and can really only figure out how to do it one way, but would rather do another because the line lengths will be dynamically generated and the mask portion won't.
Let me explain.
Assume I have a line that is <path d="M0,0 L0,100" stroke="blue" stroke-width="20"/>, I would like to mask with transparency the first 10 pixels, meaning just the d="M0,0 L0,10" portion.
I can do this, which produces the results I'd like:
<svg width="100" height="100">
<rect stroke="black" stroke-width="2" width="100" height="100" fill="yellow"/>
<svg x="10" y="0" width="200" height="200" >
<defs>
<rect x="0" y="0" width="20" height="10" stroke="none"/>
<mask id="chopmask" maskUnits="userSpaceOnUse">
<rect width="20" height="90" x="0" y="10" fill="white"/>
</mask>
</defs>
<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>
</svg>
</svg>
But the issue is that I can't seem to do the opposite with the rect in the mask, wherein I simply define the it as <rect width="20" height="10" x="0" y="0" fill="white"/> (notice only height and y are different).
Am I missing something on how do define a 10x20 rectangle and have it's mask simply hide a portion of a stroked path, or is this impossible?
If I understood the question correctly, then you need to have a mask in the form of a rectangle of fixed size 10Х20, which will be applied to the line with variable length.
In this case, you can try on a combined mask, one part of which will be opaque fill = "black" and the second part will be transparent fill = "white" and show the rest of the line.
<svg width="100" height="100">
<rect stroke="black" stroke-width="2" width="100" height="100" fill="yellow"/>
<svg x="10" y="0" width="200" height="200" >
<defs>
<mask id="chopmask" maskUnits="userSpaceOnUse">
<rect width="20" height="100" x="0" y="0" fill="white"/>
<rect width="20" height="10" x="0" y="0" fill="black"/>
</mask>
</defs>
<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>
</svg>
</svg>

<svg x="10" y="0" width="200" height="200" >

</rect>
</mask>

<path d="M0,0 L0,100" mask="url(#chopmask)" stroke="blue" stroke-width="20"/>

Works for me ... am I misunderstanding what you're trying to do?

Is there a way to select the first 3 <path fill="#2e99e5" d="M0 0h960v960H0z" stroke="gray" stroke-width="0.5"/>
and change the color?
I want to hide anything that outside a rectangle. (this i have achieved with clipping successfully). but another condition is that, 'also hide anything that comes inside the black big circle'. Now how i can achieve that?
in below example, 'yellow circle' must be eliminated'.

Below is my Svg code:-
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="500" height="500">
<g>
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
<circle cx="180" cy="150" r="30" stroke="blue" />
</g>
<g clip-path = "url(#clip1)">
<circle cx="180" cy="150" r="10" stroke="blue" fill="yellow" />
</g>
<clipPath id = "clip1">
<rect x="50" y="50" width="200" height="200" stroke="1" fill="red"/>
</clipPath>
</svg>
Erik Dahlström is right, your clip can include the entire rectangle and the cutout for the circle. This way, anything you associate with #clip1 as the clip-path will not be visible inside your circle area. Here is what it looks like for your example:
<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="500" height="500">

</g>

</g>
<clipPath id = "clip1">

</clipPath>
